Things continue to be quiet in the photography scene. We did have a bunch of new rumors pop up, including a Chinese zoom lens, another Chinese autofocus lens entrant, hints that GoPro may expand beyond the wide angle Action camera, and more. But in terms of news? Yawn (wake me when something happens again).

Gerald undoes the color world

Gerald Undone, a well-known and respected YouTuber who mostly caters to the sophisticated videographer crowd, seems to have upset a few people who only noted his "grades" for color. As in Nikon gets an A, while Fujifilm's overall report card showed a D. Nikon's Flat Picture Control gets an even better grade than A for photo accuracy.

Yes, we're back into Color Science feuds. Basically, accuracy of color versus colors people like. I should point out that I come from the video world (dating back to the early 1970's) and because video always has to worry about what's happening downstream of the capture, accurate color at capture has always been a priority. It's my priority with stills, too. I think I first wrote in 2004 that if you baked something into your original capture files (e.g. JPEG), it made the job of changing things later much more difficult. The more you baked, the more difficult later changes became, up until the point where you "burnt" you original and would never be able to recover usable data later from the burned sections.

The doom-scroll side of the world doesn't mind baking. Indeed, they count on some baking to set their images off from others in the scroll. Brighter, contrastier, more colorful, unusual color palette, and more. That's one of the things that happen when you're taking the same composition as others ;~). Pleasing color is one of the reasons why Fujifilm resonates with the content creators: picking a different film simulation gives you instant baking. Nikon's more recent foray into Recipes is similar, and even the wording speaks to "baking." 

I think everyone really needs to understand—after accounting for color blindness and cataracts—just what world they want to live in: accurate or pleasing color. I'll point out that this was the case even back when I picked up my first film camera in the 1960's. You're in one camp or the other, though these days with digital, you can be in the accurate camp and migrate any time you want to the pleasing camp. Pretty difficult to do the opposite, though.

Which brings me to LUTs in the video world. I should point out that one of Gerald's businesses is selling accurate LUTs, which is one reason why he's doing all this technical color analysis in the first place. In N-RAW or N-Log video from my Z9-generation cameras, I like his LUTs a bit better than Nikon's free LUTs. His LUTs do a better job of getting you to a "broadcast accurate" color in your base material. If you want to grade looks into that after the fact, you're working from a better original data set using his LUTs.

Better than raw

A couple of questions, a few posts, and now dpreview's interview with the Camera Intelligence's Caira camera designers remind me that we did the right thing in the beginning at Connectix in 1994 when we designed the QuickCam. It's why Apple copied what we did when they got around to building cameras into laptops, tablets, and phones. And it's a really simple idea.

Let's start, however, with what current cameras do: data from the image sensor is instantly (and sometimes within the sensor) managed into a complex physical image processing pipeline. That includes "gain" control, "correction" of raw data (in Nikon's case White Balance Preconditioning among other things), as well as lens corrections, among other things. Many of these things happen before the camera actually creates a raw data file, let alone processes the raw data into a JPEG, HEIF, or TIFF image.

What we did at Connectix was dirt simple: as few parts as possible to get truly raw image sensor data captured in real time into the CPU of a Macintosh (and eventually Windows PCs). The stream of the data was more important than getting each data packet "corrected." Particularly when we and others eventually combined the stream of image data with streams of other data, such as gyroscopes. 

I'll take a really simple example to illustrate. Photons are random. So when you capture a snapshot of them via a shutter (electronic or mechanical) you freeze whatever random photons you've managed to capture. The randomness of photons is our primary source of visual "noise" these days. So what if you captured the moment via one frame of image capture but captured the data stream before and after? You could look at the pixel data for two, four, eight, or sixteen images in the stream and, where there's not motion, use methods to "fix" the photon randomness (I published an article back in 2011 about how to do this; I talked about it at a graphics conference a decade earlier). With the QuickCam we were even trickier: we used the stream to constantly evaluate both exposure and color change (e.g. someone turns on a light), as well as to produce images.  

To a large degree, the smartphone cameras have gotten better at final results because they're doing some of these stream related things (as does the Caira), particularly in low light. Meanwhile, the camera makers have gotten worse. That's because they rely upon a physical image pipeline that does pieces of the work all along the way, plus the sensor-to-ASIC path goes through a limited amount of memory and not always at the speeds that the smartphones work at with their direct to compute cores approach. 

Which brings me to another point: we always knew processors would get faster. Moore's law itself predicts that. So keeping the connection between image sensor and CPU as short and unmanaged as possible was always going to provide the ability to do more later at the CPU side. Today, that includes a lot of machine-learned things in the smartphones (AI, if you will). The dedicated cameras are doing that on limited (or no) real-time streams well away from the image sensor, and with process size cores that are far bigger, more power hungry, and slower than the mobile devices. 

So what's better than raw data? All data as it is produced, and the full stream of it, not a slice of it every now and again. Which leads me to Professor Eric Fossum's work. He was in on the original CCD and CMOS image sensor development at the NASA Jet Propulsion Lab (JPL), but at Dartmouth he helped develop what he originally called the JOT image processor (now called Quanta), which basically just produces a stream of data that tells you when and wherefrom every photon arrived at the image sensor. After introducing a 41mp 2.2-micron sensor in 2022, the company he and his students started has gone 100% silent. I can't tell whether it was absorbed by someone else or what, but I can see that the quanta image sensor is still getting development activity. 

So you wanted to know what's better than raw. It's knowing when every photon hit the focal plane and from where. Couple that stream of data with all the other image processing things that are going on in today's very sophisticated and fast computing cores, and I believe you'll get even better results than we obtain today.

Reader Question

Carry on my wayward friends

One of the things I've been trying to build in the background is a huge database of reader questions with my answers. I've been doing "reader questions" off and on here at byThom for decades, but it's time to start dialing that in a bit more. So expect a reader question coming with each future News/Views. Today's question: "What’s the heaviest lens you’d use when carrying the camera using a neckstrap?"

Answer: I have a simple rule of thumb for this: if the mass of the lens exceeds the mass of the body, you should be carrying the combination by the lens (e.g. strap attached to the tripod collar). The more the mismatch and the more the lens mass is far away from the mount, the more important it is that you follow this rule. That's because the lens mount is the point of weakness between body and lens, and the mount on both is designed to break once stressed past a certain force level. The reason for that is that repairing a mount is far cheaper than repairing structural damage to the body or lens structure. 

Beyond that, camera+lens these days tends to exceed three pounds even on the simplest of systems. That’s a lot of force on your neck, too. Almost none of us who carry cameras all the time use traditional neck carries. At a minimum, we use shoulder straps, but this is where Cotton Carriers and various sling belts and harnesses come into play. Even then you need to be careful, as just hanging a camera+lens off a carrier doesn’t isolate g-forces on the mount unless there are multiple points of contact.

Now Arriving at Tab 2

Only three months late

This week I published my first completely redesigned Web site: filmbodies.com. I've starting with that site because it's the smallest of my sites and the one that gets the fewest updates and additions, and I wanted to make sure things work as I want them to in this new style before committing to the bigger bythom.com and zsystemuser.com sites, which would need a lot of extra work if I got something wrong enough that I needed to abandon the style and start over. 

It's been a long, winding path to where I ended up. I have so many different prototypes of sites now I'm going to have to build an archive drive of just all my ideas and testing. In the end, though, I decided to keep things closer to what I've been doing rather than further. That said, there are a ton of behind the scenes changes, some of which I coded myself, some of which were coded by others. But filmbodies is now my first site that 100% respects screen size, plus it also respects Night/Day settings on your devices. A 404 page, redone SEO, and other missing elements are all features, though I haven't hooked up the contact page, 404, and redirects yet. Overall, filmbodies should be leaner and faster. I can also update it quicker, too, plus site backups are now automatic.

Even more exciting is that I rewrote (or at least re-edited) every key article on the old filmbodies site, then added a couple of new ones just because it's difficult to stop me at anything once I get started ;~). So much so, there's even a brand new, free book available to film SLR users who visit the site (though you can enter a donation price, should you care to). The letters on my keyboards seem to be wearing off. I've also cleaned up a lot of images because on the original site many of them were only 384 pixels wide! That tells you how far things went back, as I originally used a two-column site design with a maximum column size of 500. But now, all will be new again. New text, new photos, new everything.

Now that filmbodies is live, it's time for me to start knocking down other site dominoes...

And in other news

▶︎ DxO PhotoLab 9.6This new update adds the DeepPrime XD3 noise reduction (for Bayer sensors), adds diffusion on AI masking to make the edges more natural, and adds a new high-fidelity DNG compression routine.

▶︎ Affinity gets bug fix. The new combined Affinity application was updated to version 3.1, claiming to fix over 200 bugs. Canva added a new light interface for those that objected to the dark one, a new Convert to Curves function that changes pixel selections into editable vector curves, a new Live Tone Blend Groups function, and some other minor bits. Affinity seems to generate a love/hate response from users, mostly due to its combined Illustrator/Photoshop/Indesign mimicking UI, but frankly, it's a free Photoshop (near) clone that works, and I'm not sure how you can hate that.

▶︎ GIMP gets an updateSpeaking of Photoshop alternatives, GIMP (Gnu Image Manipulation Program) just updated to version 3.2, which finally adds non-destructive layers. In fact, layers got a lot of additional attention in this release, though not for the sort of layers that we tend to use with photos. Instead, the new bits have to do with text layers, linked layers, and vector layers, which are more graphic-design oriented. The MyPaint Brush tool was updated, as well as the Text Editor. The UI got a lot of touchup and adjustment, though it still has a geeky, old-school Unix flavor, and now JPEG 2000 and AVCI images are also supported. Curves now supports Presets. There's even a new Cornish language version of the UI, which brings to 86 the languages GIMP supports.

▶︎ Another Viltrox Vintage FlashViltrox introduced the Vintage V2, a US$37 basic flash unit with a rechargeable lithium battery. While there are TTL compatible versions for Canon, Fujifilm, Nikon, and Sony, the only controls on the flash are really Automatic plus 1/2 to 1/16 power. With a GN of 6 (feet, about 2m), it's not very powerful. The best application for this flash would be in situations where minimal fill is useful.

It's tempting to say "nothing happened this week." Everyone in Tokyo is taking a breather after a successful CP+ show, after all. But of course a lot did happen (e.g. war is now ongoing, more tariff gyrations, fear of economic slowdown, yen appreciation against the dollar while falling against the Chinese Yuan Renminbi). For Fujitsu, Nikon, Panasonic, and Sony, their fiscal years end at the end of March, and the last month hasn't quite worked out exactly as each expected. When the full year financial results are reported in late April and early May, I expect that to be followed by some new short- and mid-term management plans that were at least partly triggered by recent events. Nothing earth-shocking is in store as far as I can tell, but I'm hearing a lot of micromanagement bits starting to leak in Tokyo, and even here in the US subsidiaries.

Tip

Reducing Noise on Input

Bill Ferris, an Arizona wildlife photographer who's active on dpreview recently wrote a short post that echoes what I've been teaching for some time now. To reduce noise in your input data:

  1. Use the widest aperture that provides acceptable depth of field.
  2. Use the slowest shutter speed that stops subject (and camera) motion.
  3. Fill the frame with your composition.

The first two are about optimizing exposure. Exposure is LIGHT filtered by APERTURE filtered by SHUTTER SPEED. When you use too small an aperture or too fast a shutter speed you're effectively increasing the randomness of photons in your image, which is the primary source of "noise" these days.

The third is more about the visibility of noise. If you have to crop your original data to get your final composition, at the same output size you increase the visibility of what noise was captured. So if your goal is a 24" print and you cropped your original 2x and output to that size, you'll get a significant increase in the visibility of noise that is in the image versus having enough full frame pixels in the first place. This part is trickier than you think. One reason why I stopped using m4/3 is the 4:3 aspect ratio. Almost all my output is 16:9 these days, so in using 4:3 for the capture I'm always significantly cropping my final image. This makes the area captured that's used in the final image even smaller than I obtain with full frame, thus amplifying the randomness of photons. (Note that choosing sensor size is all about trade-offs. For me, the trade-offs no longer work great. For you, they might. See next.)

Yes, noise reduction software can help, but that's dealing with things you've already captured. Remember, my mantra is optimal data capture, optimal data processing. What I'm talking about in this tip is optimal data capture. Where noise reduction software comes into play is with optimal data processing.

After I launch byThom MAX I'll eventually serve up my three-part seminar on noise: (1) sources of noise; (2) minimizing noise during capture; and (3) dealing with noise after the capture. One of these (long) presentations is already done. The other two are in progress. Until then, enjoy this brief hint at a key component of presentation #2.

The case for high-end APS-C

In this week's tip, I mentioned aspect ratio, capture area, and tradeoffs. I'm lucky enough to be able to fill the full frame with my subjects, both on the sidelines at sporting events, and in Africa taking wildlife photos. While I "suffer" from size, weight, and price penalties doing so, matching top full frame bodies with the best possible lens is still my primary choice. I'll put what I create up against anyone, as I'm using optimal gear using optimal capture techniques. 

But realistically, most folk on safari aren't getting the animal approaches or carrying the really long lenses I and other pros do. Particularly in Kenya and Tanzania, there are times when you simply can't fill the frame with your composition, even at 600mm. The nice thing about the Nikon Z8/Z9 is that they also are convenient APS-C cameras, too, by simply flipping a setting (which can be automated into a button). Sure, you only get a 19mp crop that way, but if that 19mp is fully used and you've set exposure properly, the results can still be stunning at up to about 24" long axis. 

One reason the Nikon D500 and the Canon 7D DSLRs were so popular is that they gave you much of the top end body capabilities and performance in a smaller package where you could use somewhat shorter optics, plus you saved a ton of money by equipping that way. I know of one professional sports photographer who has never given up on his D500's because he gets what he needs from a lighter, smaller outfit. Newspaper and Web sports photos simply don't need massive file sizes, and photos are used at sizes that don't reveal the noise gain from the smaller capture area. 

There's no accepted definition of consumer, prosumer, or professional when it comes to cameras. However, I'd tend to point to the D500 and 7D (and now R7) bodies as truly prosumer, as they have professional body attributes that are reduced slightly by some consumer-type approaches. For instance, sensor size, which has a big impact on cost, all else equal. 

Nikon got burnt by overextending in DX (APS-C) during the DSLR era. As sales volumes came down, Nikon found that they hadn't cleared the previous generation of cameras when they were launching new ones, so at one point Nikon was selling anywhere from eight to twelve (!) cameras in a very tight spacing. After the D500, Nikon moved radically away from proliferating APS-C cameras. 

Sony has done something different. They, too, were over proliferating APS-C early in the mirrorless era (NEX and A#### cameras) and ran into the same inventory pile up. Now they've moved to four spaced-out models that don't iterate very often (if at all). 

Canon seems to be the only one iterating mirrorless much like they iterated DSLRs, with models all over the spectrum, including the arena this comment is about: high-end APS-C. The Canon R7 and Fujifilm X-H2s are really the only two remaining high-end APS-C cameras that fit the prosumer definition I prefer to use (pro features and performance with some consumer limitations). Apparently, Canon will update the R7 sometime this summer, pushing it even closer in pro features and performance. 

But where's Nikon? They were the ones that really established this market (with the D100 originally, and particularly with the D300 and D500 later on). Nikon even has the right lens set in the Z System for the sports/wildlife DX user (e.g. the 400mm f/4.5 VR S would be a great lens to pair with a Z90 prosumer body, as well as the 70-180mm f/2.8 for a second body). 

And where's Panasonic? Their m4/3 start seems to have them afraid of even trying APS-C. 

I'd argue that top-end APS-C bodies should be present in any mirrorless lineup that wants to be complete and win more customers. Canon looks like they'll have that with the upcoming R7 II. Fujifilm still needs to up their game with autofocus performance on the X-H2s. Nikon needs something far better than the current top of their APS-C line, the Z50II. Panasonic needs to stop watching pitches go by and swing their bat. Sony thinks the A6700 is top end enough, but I'd disagree on a number of levels, starting with the position of the viewfinder, which impacts rotation stability on fast action. 

In particular, Nikon and Sony seem to be iterating less often and concentrating mostly on rationalizing a modest number of full frame bodies. This is a little like an auto maker deciding that they don't need to make a full range of product, just a quiver of mid-size and large SUVs. We know what happens when you do that: you get smaller. I wonder how small a camera maker can let themselves get before they become irrelevant. Perhaps Sony doesn't worry about that because they have a history of casting off businesses that become irrelevant. But Nikon doesn't have that opportunity, as Imaging (cameras and lenses) are near 50% of their overall business, and the only group that is consistently profitable enough to keep expanding the overall company. 

So while I'll continue to use my full frame Nikons, I'll be the first one to congratulate Nikon when (if) they come out with a high-end APS-C model. It would be the right camera for so many customers, I just don't know why it doesn't exist already.

▶︎ Photoshop gets an AI Agent. Adobe's latest Photoshop public beta includes a new AI Agent, which you can chat with to process your image. Short form, you tell it something and it uses the built-in Photoshop tools to accomplish that. For instance, you might type "reduce the highlights and boost the shadows and also remove distractions." This works a bit like an Action, in that each step will be executed individually and thus leave an entry in the History panel, but it works slower than an Action so that you can see the steps as they are performed. You can also use the chat to ask the AI how to do something, and it will just describe the steps it would take instead of actually performing them.

My take on this is that it's useful if you don't know how to do something specific, such as apply a blend mode only to the highlights, but this new AI feature is not something I'd tend to use myself. For instance, this AI Agent doesn't agree with me on cropping, let alone what constitutes a highlight or shadow. Thus it is more brute force than I would tend to use Photoshop. Great Photoshop processing never reveals what was done and requires subtlety in decision making. I don't believe the Agent is up to that level at this time.


Pending Reviews

I'm in a bit of a rock and hard place location at the moment. I've continued to work on reviews and get them ready to publish, but I'm prioritizing getting new site designs readied and rewriting everything I've published before on filmbodies, bythom, and zystemuser, while also building out the product for byThom MAX. I apologize for the lack of reviews lately, but that log jam will break, probably early this summer.

To wit:

  • Ricoh GRIV review will appear with the refresh of the bythom site.
  • Nikon ZR review will appear with my ZR book sometime in the next month or two on current site.
  • Additional Z-mount lens reviews will likely wait until the site refresh this summer:
    • Tamron 16-30mm f/2.8
    • Nikon 16-50mm f/2.8 VR DX
    • Nikon 24-70mm f/2.8 S II
    • Nikon 24-105mm f/4-7.1
    • Nikon 35mm f/1.4
    • Nikon 35mm f/1.7
    • Tamron 35-100mm f/2.8
    • Nikon 50mm f/1.4
    • Nikon 58mm f/0.95 NOCT
    • Tamron 70-180mm f/2.8 G2
    • Nikon 70-200mm f/2.8 VR S II
    • Tamron 150-500mm f/5-6.7 VC

Most of those reviews have completed testing and are completely written, but awaiting time for me to do editing and provide examples, charts, and peripheral materials. So there will be a spurt of reviews hitting once the sites are refreshed.

At the moment I have six Chinese Z-mount lenses here in the test queue, but I'm waiting to see what happens with mount licensing before I go further with them. I also haven't acquired a Nikon 28-135mm f/4 PZ, as I don't know how much interest there is in that lens. Likewise, the 35mm f/1.2 S is a bit out of my wheelhouse, so I don't have one of those currently in test. I will, however, eventually get round to those two Nikkors, as I want the new zystemuser.com to be "complete." 

If you have a specific question about any of these products, by all means ask me via email and I'll try to give you a quick answer. 

Weekly News and Commentary March 1 to 8

LEDE ON

By this point last year we had four significant camera introductions. This year, none. Every company I talk to quietly confirms that their original plans for this year have all been pushed later and later, to the point where some off-the-record-but-honest responses tend towards “we don’t know when our next big product intro is going to appear; later this year is our best guess.” 

The AI elephants in the room have got all the mice scrambling for floor space. When I talk to my supply side friends, they all tell me “100% of what we’re shipping is going to AI demands.” That starts with chemicals and wafers, and ends with completed chips. I’ve been told that even Apple is scrambling to keep their supply chains going full steam. So to continue the analogy: even the cape bufallo is finding the room crowded and difficult to navigate. 

This isn’t going to let up in 2026, as the current stated plans of the AI elephants indicates that they'll want even more of the room in 2027. Meanwhile, we’re in the midst of key top management planning time in Tokyo, as the end of the fiscal year for all but Canon at the end of this month triggers final consideration on how to make the coming year better. Through the grapevine I’ve heard a couple of the ideas being considered in Godzilla’s stomping grounds. Those won’t work. Godzilla will still stomp them (oops, my keyboard seems to have substituted a new metaphor!). The ideas that might work at keeping sales numbers up are (a) more significant firmware updates; (b) better marketing, particularly in customer education; (c) deeper targeted discounts that aren’t 100% on repeat but linked to (b) and (d); (d) event-driven customer experiences; (e) bundle parties (cameras plus lenses producing discounts); and (f) making a louder splash when you do have a significant new product to introduce.

But a new great camera with a new sensor, new ASIC, lots of updated features and performance, that will make you run to the store to see it? We’ll eventually get a couple of those this year, but they’ll be later than expected, and probably available in lower volume than demand. I doubt those few new key cameras will move sales numbers much.

WPPI 2026

bythom-US-NV-LasVegas-2026-GFX100II-6194w

Once again I attended the wedding and portrait oriented show for professional photographers that occurs each year in Las Vegas. I went mostly to keep in touch with what’s happening in an area of photography that I don’t generally practice, but also because I’m working on a book that has a section on lighting, and lighting and posing are the two headline ingredients at the show. It’s not that I don’t know light, having lit my first studio in 1973, it’s that running full lighting setups is not something I do every day, and I wanted to make sure that I’m not fogetting something as I write new material.

I’m not going to get too into the WPPI details here—if you have a specific question drop me an email and I’ll try to answer it—but I did have a number of observations as I attended sessions, took photo walks with instructors, and browsed the large trade show of gear and services that runs alongside the educational components: 

  • The back of the camera is the primary compositional choice. I mentioned this last time I wrote about WPPI: most photographers here simply compose with the Rear LCD. There were a couple of holdouts. Mostly old-school names you’ve heard before who started with SLRs, used DSLRs, and now treat their mirrorless systems the same way (see Joe being Joe, below). But the younger crowd would be quite happy with the viewfinderless ZR, and I saw quite a few of those around the show. As I’ve noted before, when you’re dealing both with your camera and someone posing in front of it, hiding behind the viewfinder tends to break the connection between you and your subject. Connecting with your subject is how you help interact with them and adjust their pose.
  • CaptureOne is the tether choice. Virtually every live demonstration (of which there were hundreds) had the camera tethered into a MacBook running CaptureOne. A number of presenters even went so far as outright claiming “CaptureOne is the only reliable choice" for tethered work. I never saw a hitch with a CaptureOne tether in any session, though there were lighting and audio hitches, so maybe there’s some there there to that claim. Also: almost everyone was using some of Tether Tools bits and pieces (e.g. cabling). 
  • Creativity is not dead. On a Fujifilm walk with a monster combo of GFX100II and 20-35mm f/4 lens in hand, instructor Chris Berry told me to “break the camera.” Not literally, of course. But rather stop doing things the way I usually do. It’s true, as a raw user, I don’t tend to break outside of long-considered exposure norms. So I grabbed Elvis, cranked up exposure compensation to +3EV, dialed in a filtered Astia+G, and took the image at the head of this section. Not. What. I’d. Normally. Do. And that was sort of the point Chris was making: the creativity you need to stay afloat in this business comes from pushing boundaries, trying new settings, and “breaking” things. Indeed, that’s one of the places that “personal style” comes from. When Insta was new, running a filter on your capture was the thing that set an image apart and possibly stopped a doom scroll (to some degree, still does). But if in going outside the usual box you start finding something you like and that tests positive when you show your images to others, then you’re doing the right thing. Ultimately, photos are to be looked at, examined, maybe even studied and analyzed. If your image looks like every other one out of a Canikony at default settings, it would be incredibly difficult to sell your photography to others as a service. WPPI has thousands of attendees who are making money off of photography. One reason they do is that they keep tuned in to what’s happening on the “creative” side. (And yes, that image is +3EV in exposure. At the end of this news story, I’ll show you how I processed it to get closer to what I was thinking. But it’s pretty incredible what the Medium Format image sensors can hold in terms of dynamic range, and the level of detail at 100mp is pretty amazing. The above image in its original form would print 37” on the long side, by the way.)
  • But don’t forget to do what sells. Another speaker went through the process of “breaking” something to demonstrate images that catch attention, but he runs a production studio and keeps careful track of his actual sales. He reports this: the creative images pull people into the studio, but customers still end up choosing to buy the more traditional ones. So make sure that you’re still giving them that option. This plays into something I learned when doing editorial work for magazines: (1) the magazine was attracted to me because of a style/look I produced; (2) they asked for images specifically that fit their style/look and tended to run those over (1). But every now and then, my style/look won the call, which triggered other magazines to ask about my availability. Put another way: do what sells, but also do more. That more should be unique to you and the result of your creative process going further than what you were asked for.
  • Speedlights are too old school to consider. Virtually no one was using camera-company flash units. The standard in most demonstrations was Profoto A2 and B30 strobes. A few used the lower cost Godox (or Adorama Flashpoint) similar lights. The first reason the on-camera flash units get no love is output: you get more light from the big rigs. The second is ease in “modification.” Soft boxes, grids, gels, and more all work very simply in the current Profoto designs, and are extremely fast to set up and/or swap out. When you really want to control the light as do the portrait and wedding photographers, you need a lot of power, up close, and softened. Of course, a full three-light and modifiers Profoto rig is going to set you back US$6000+, and you still need stands to put the lights and modifiers on. So it’s a tough sell. But instructor after instructor kept making it look easy, so I’m sure Profoto made quite a few sales.

Joe Being Joe

I’m always up for watching Joe McNally in action. He tends to start out from a tame starting point that isn’t a lot different than the rest of the pack, but as he starts working a scene his special powers start heating up and next thing you know you’ve got a juiced up Full Joe running around the room. A good case in point was his presentation at the Lighting Summit, where, like most of the other instructors he began with “a model and three lights” and did the usual things with them. Here’s Regular Joe making soup:

bythom-US-NV-LasVegas-2026-Z50II-6132

You see Joe at the left, his model and some of the lighting in the middle, plus the result of the image he just took via the CaptureOne tether on the far right. (Pardon the exposure here; there’s virtually no ambient light in the room, and I have no control over the stage light or the projector. If you’re wondering: Z50II with the 16-50mm f/2.8 lens at ISO 6400 to 12800 on these images, as I’m using a slowish shutter speed to keep the frequency-based ambient lighting from throwing color bands and drifts.)

At some point as he’s working, some secret chemical starts getting dispersed into Joe's bloodstream and he begins building his superpowers. At some point he'll wonder if he really wants to just make soup any more. Maybe a spicy salsa, stew, or curry instead? I mentioned the “creative” side above, and one aspect of that is noticing things and another is not self-editing. These are things that the superpowered Full Joe does in spades. 

Eventually Full Joe jumped off stage with his model and one light, started interacting more with his model asking her to do nontraditional things (acting!), raised the light over her head, engaged the audience in what he was thinking, and ended up with this setup:

And here’s what came out of his camera into CaptureOne:

bythom-US-NV-LasVegas-2026-Z50II-6151

The strange ceiling light and some of the backlight color comes from the fact that Joe added two Profoto A2’s with colored gels behind the audience and pointed them straight at the camera (you can see them on the previously taken images on the far right, before he repositioned himself and the model so that the lights didn’t appear directly. Again, this is me taking a photo of a screen showing the CaptureOne tether, so I have no control over the color and contrast. The actual image looked far better on Joe’s laptop, obviously. 

Joe being Joe, he also spouted something new I hadn’t heard him say before, and that’s about aspect ratio. Basically Joe says he’s mostly using 1:1 as his aspect ratio now because then he never has to turn the camera on its side. So much for vertical grips.

One of the things I’ve been planning to do with byThom MAX is cover conferences and trade shows more extensively, including new things such as video, interviews, live streaming, and more. But the infrastructure for byThom MAX isn’t done yet, so you’ll have to settle for today’s abbreviated text and photo sample. I want to “always be teaching” in MAX form, so expect me to venture into that in new ways.. Who knows, maybe I’ll become the world’s oldest TikToker.

Z Versus China

It seems clear that Nikon has gone completely cease and dissist on Chinese Z-mount lenses recently. The Viltrox suit coupled with letters from Nikon lawyers makes that perfectly clear. Many of those Chinese lens makers (or at least their US distributor) were at WPPI, so I spent time there asking the obvious questions. 

No one would talk much in the way of specifics, but the generality was pretty much always “we’ll still be selling Z-mount lenses in the future.” I did note that the ones that seemed the most nervous and vague about what’s going to happen were those with “performance” autofocus lenses. E.g. Viltrox, but not Laowa.

Which brings me to a hypothesis. Nikon has a dozen or so patents surrounding the Z-mount. Some of those are size and physical attributes, which almost certainly wouldn’t hold up to scrutiny in court and can be easily reverse engineered in a clean room. Others are extensions of the F-mount protocols, which have been known and used by third party lens makers without Nikon’s permission for decades now. It would be difficult for Nikon to assert those F-mount patent specifics now, as they’ve not done anything I can see to protect that information in the past. The FTZ adapter pretty much proves that Z System cameras still understand and can use F-mount protocols, when necessary, as the FTZ turns out to be nothing more than a signal pass-through for the most part.

Which brings us to the Z part of the Z-mount communications. For instance, there’s a second synchronous serial data stream now, and that appears to be there to manage better focus performance. Nikon is just starting to unleash that themselves, and I believe that one of the Z9II’s new features will be related to that new channel, as well. You have to ask yourself, for instance, why do the 24-70mm f/2.8 S II and 70-200mm f/2.8 VR S II focus faster? Yes, some of that’s the new SilkySmooth focus motor system. But I believe some of the faster focusing is due to specific Z-mount protocols, and that will become clearer with the next generation of cameras from Nikon.

Viltrox is also entering into the “focuses faster” realm now with their PRO lenses, and my hypothesis is that Viltrox has now picked up on something beyond the base F-mount protocols and are implementing this on their lenses. Couple that with Nikon completely missing their lens attachment rate goals (2:1 was the stated goal, they’re getting <1.5:1 out of China), and it seems that Nikon sees the problem being a financial one, which is the reason that it now appears that they’re asking for mount licensing fees. 

Coupled with this is the entreprenuerial nature of the China lens market. There’s a lot of cross licensing, design sharing, and engineer movement going on between the various Chinese lens companies. So knowledge about what works and what doesn’t is getting shared very rapidly among the Chinese lens producers. This suggests a couple of things: Viltrox is the first to be sued because they are the ones showing the most impressive growth and now starting to nibble into the arena where Nikon S lenses play, but the entire Chinese lens market is learning from Viltrox, thus the warning salvo of cease and dissist letters. 

I’m not against Nikon asking for companies to sign mount licenses and even paying FRAND (fair, reasonable, and non-discriminatory) royalties. However, the way Nikon is going about things and the fact that they haven’t communicated to Nikon customers what they’re doing and why is just clearly a bad business decision getting badder by the day. All this in a year when there won’t be a lot of new camera announcements from them, too. 

I’m starting to see this as a “make or break” year for Nikon. Either they remove these frictions, launch a successful Z9II and some key lenses of their own, plus figure out how to move more units through dealers, or they don’t, don’t, and don’t. In the “make” case, Nikon will see sales growth and some market share increase to continue the positive path they’ve been on. In the “break” case, Nikon will lose some customers and find themselves in a deeper market share war with Fujifilm for third place, with the potential for dropping to #4. 

It’s probable that top management and the legal team in Tokyo don’t believe any customers see any of this legal action. They’d be 100% wrong. It’s possible that top management thinks that customers won’t be concerned about any of this legal action if they did know about it. That would also be 100% wrong. Nikon needs to resolve the mount license situation quickly, and the basic way to do that is FRAND patent licensing coupled with making a clear announcement about that.

Wrapping Up

And in other news

▶︎ Apple adds Neo, updates other MacBooks. It was a big week for Apple in terms of updates and discontinuations. I won’t be updating my full Mac advice articles on this site until I deploy the new site design, so we’ve got a lot to cover here in short form:

  • Discontinued: MacBook Air M4 (13 and 15”), MacBook Pro M5 (13” with 512GB SSD), MacBook Pro M4 (14 and 16”), Mac Studio M3 Ultra with 512GB memory, Studio Display A13, and Pro Display XDR. Many of these are great products for photographers and are seeing discounting as retailers try to get rid of their inventories. Don’t be afraid to buy those that I recommend.
  • Added: MacBook Neo, MacBook Air M5 (13 and 15”), MacBook Pro M5 (15”) with expanded SSD, and MacBook Pro M5 (14 and 16”) with Pro and Max chip options, two new Studio Display options (regular and XDR).

There’s a lot to unpack. First, generational speed gain is about 15% from M4 to M5, all else equal. While that sounds modest, as you move into the advanced versions (Pro and Max) some of the core changes may make more of a difference, if utilized. That said, most of you won’t notice the difference between M4 and M5 performance, all else equal.

Let’s start with the MacBook Neo. It’s very tempting as it has a low starting price and doesn’t give up a lot to get there. But I won’t be recommending it to photographers because the storage limitations (max 8GB RAM, max 512GB SSD) are too constraining. It’s not that the Neo can’t do Lightroom/Photoshop, it’s that you’re almost immediately into the Ram Doubler-like compression and swapping as you work on images, even 12mp ones. As you start to do more, you’ll wait more. I just don’t see a Neo being able to grow with you as you start taking and processing a lot of images. If anything, you’ll chew through the life of the small SSD fairly rapidly with all the swapping going on. The more megapixels your camera has, the more you’ll feel that.

On the other hand, Apple did something I 100% approve of with the new MacBook Pros: 1TB is now the minimum SSD size. For a prolific photographer I’d still recommend storing your images on an external drive, but this larger built-in drive size is no longer likely to get in your way of storing your catalog, cache, and swap files. A base level 14” meets all of my basic requirements for a photographer’s laptop now and lists at US$1699. I’d still consider upping the RAM to 32GB, as RAM=performance in the Apple Silicon world. That extra RAM will add US$400 to the cost, though. But the result would be a wickedly good machine that travels well and should last you for some time. You can still go crazy upgrading a 14” MacBook Pro (or 16”), getting you all the way to US$7049 (M5 Max, 40-core GPU, 128GB RAM, 8TB SSD, nano-texture display). But at that extreme you’re deep into “competes with highest-end desktops” performance, and I’m not sure why most of you need that in a portable. (Disclosure: some of us do. I have a MacBook Pro M4 with 64GB RAM and 8TB SSD, but that’s because I need my desktop when I travel.) What I’d suggest to all those considering the MacBook Pro is to look at sales on the M4 models, but definitely not be afraid of the lowest level M5 models.

The MacBook Air is somewhere between the Neo (not a great photographer tool) and the MacBook Pros (superb photographer tools). We now have 13" and 15” Airs with M5, 16GB, and 512GB SSD starting at US$1099 and US$1299 respectively. If you want a really excellent option, pick the 15” M5, 32GB, and 1GB SSD at US$1899. That’s not going to have issues with Lightroom or Photoshop, give you some growth space, and provide excellent performance for virtually anything you might do. 

Meanwhile, the Apple external display choices need to be noted: the basic US$1599 Studio Display didn’t reallly change, it mostly got an updated A19 chip at its core (the original was A13). The more expensive Studio Display XDR is where changes came: downgraded from 32” and 6K to 27” and 5K, and updated to A19 Pro chip with a built-in camera. The XDR version is now “only” US$3299, though. Note that neither of the new displays work with Intel-based Macs; we’re in an Apple Silicon world now. 

All in all, Apple is pushing Mac very rapidly in capability and performance that now provides workstation-level ability in a highly portable form. Apple’s not done with Mac for the year, but this first salvo is pretty darn awesome. Somehow Apple has kept a lid on their pricing (with a little juggling) while continuing to push performance at a high pace. The MacBook Neo’s an insane machine for its US$599 price if you’re just looking for a computer to do Web, email, office productivity, and other basic chores. But it’s not quite enough for an active photographer on the road; the base MacBook Air would be the better choice.

As promised, here is the start of one of my “processed” versions of Elvis. The primary difference is that I’ve applied so far is an anamorphic flare. What I was thinking about as I was “breaking” the camera was “Elvis wears white and he’s in heaven and I’m at the museum where all the old Vegas neons goes when it dies,” so I want an all-white, almost heavenly look. 

So what I’m doing here is breaking Photoshop. It needs a lot more breaking to get to what I was imagining, but now you might be able to see where I’m headed. I need to get home and work on this with the big computer some to do what I want. The flare needs to go behind Elvis and I need more flare effects. It’s difficult making these decisions on a laptop.

Weekly News and Commentary Feb 24 to 27

LEDE ON

Canon announced that they had the number one market share of interchangeable lens cameras in 2025, and this was for the 23rd consecutive year (since 2002). Source for this claim? "based on Canon survey." What Canon doesn't say is that at least 10% of that volume probably came from them still seeing low-cost DSLRs. Nevertheless, Canon is a bit of a juggernaut, selling nearly 3m units in a 7m unit overall market. I do note that Canon isn't claiming an overall market share value this time around, probably because it slipped to 41%. 

Meanwhile, at the CP+ show,  CIPA announced their prediction for 2026 camera volume: interchangeable lens camera volume is expected to drop 2.5% this year, while compact cameras will go up 15.5%. Good thing Canon is resurrecting those PowerShot models, huh?

Commentary

The Odd Case of Sigma DN

Sigma was one of the early players in lenses for mirrorless lenses, with three DN lenses originally for the m4/3 mount, and later expanded to Sony E, Canon M, and then further expanded to Fujifilm XF and Nikon Z. (As a reminder, Sigma's DN lenses are for crop sensor cameras, particularly APS-C.)

This week, Sigma introduced a rethink of one of their wide angle options (now 15mm instead of 16mm). But it's only for Canon RF-S, Fujifilm XF, and Sony E mounts. What happened to the Z mount? 

Nikon and Sigma have always had a bit of an antagonistic relationship, partly due to patent contestation. It's easy to hypothesize that this might have something to do with dropping the Z mount. However, I think it's something more basic: Sigma has tended to be running near or at capacity and the Z mount is, as far as I can tell, the fourth highest selling APS-C mount. I'd guess that Sigma simply didn't want to restrict their ability to serve the primary APS-C vendors in order to support a fourth. That's despite the fact that there are no Nikon DX prime options that come close to this focal length, so Sigma would have very few—and only Chinese—competitors for a 15mm f/1.4 in the Z mount.

Still, odd things are happening all over in the world of lens mounts these days. Canon clearly is trying to restrict full frame RF lenses produced by others, Nikon wants third parties to get approval for producing a lens in their mount, and Sony is finally starting to realize that their more open mount helps camera sales but is now hurting lens sales. Meanwhile, the Chinese competitors keep getting better, and they're providing lower cost options (despite the tariffs here in the US). 

What I'm seeing is that every one of the Japanese lens manufacturers (including camera companies) is trying to hold niches and particular customers. This is making for odd disparities. So much so, I think it's time I resurrect my Buzz, Buzz shorthand. (Buzz Buzz was my way of acting like an annoying fly to Nikon's marketing and sales group.) With Nikon producing three DX camera bodies and only seven DX lenses, Nikon's attacking the crop sensor market with very few arrows in their quiver (Buzz, Buzz). The only bright spot for Nikon DX is that Viltrox is adding some other options, though now Nikon is suing Viltrox, so there's a bit of Buzz Buzz Shoot Foot happening in Tokyo at the moment.

CP+ Lens Launch Lowdown

I earlier indicated that CP+ would be a pretty lens-focused show. That's turned out to be the case, particularly as there are no new (production) cameras being shown. Here's what was announced just prior to and on opening of the show.

7Artisans' 2Fer at CP+

The official release of their autofocus 40mm f/2.5 for the Sony FE mount was announced, with a Z-mount version in the wings. The bigger story (literally) is the autofocus 135mm f/1.8 for the L, Nikon Z, and Sony FE mounts. I'm told the likely price will be about US$800.

Brightin Star's Briefing at CP+

  • 35mm f/1.7 for Leica M.
  • 50mm f/2 Tri-Sight for Canon RF, L-mount, Nikon Z, and Sony FE. The "tri" refers to the ability to switch focus style (bokeh): smooth, prime, and foams (bubble) are the three choices. A bit gimmicky for me; I'm not sure I want to change bokeh using the same lens, but maybe that's just me.

Samyang's Sling at CP+

Korean lens maker Samyang showed up with a number of new lenses. developed in conjunction with Schneider-Kreuznach: 

  • L-mount: 14-24mm f/2.8 and 24-60mm f/2.8  (previously seen in Sony E mount)
  • FE-mount: 20-50mm f/2, 28-135mm f/2.8, and 60-180mm f/2.8
  • prototypes: 200mm f/1.8 and 300mm f/4

Those last three are completely new, while the others have been demonstrated before and are slowly leaking out into the world market.

Sigma's Salvo at CP+

Sigma had four lens announcements for the big Japanese Consumer Show (CP+). 

First up, we have the 15mm f/1.4 Contemporary, which is a US$580 APS-C lens for the Canon RF-S, Fujifilm XF, and Sony E mounts (but not Nikon Z, see below). The Fujifilm and Sony versions have aperture rings, the Canon version has a Command dial. The big claims to fame here are excellent sharpness at a very low weight (7.8-8.5 ounces, 220-240g). 

For the full frame crowd, Sigma introduced a redesigned 35mm f/1.4 Art II lens for the L-mount and Sony FE mount at US$1060. I like Sigma's pitch on this one: "The original Art lens, even better." The emphasis here is in optical quality, and the examples I've seen so far from this lens really do have a very nice overall quality to them (including what looks to me like better bokeh). 

A development announcement and prototype showed up for an 85mm f/1.2 Art lens (L and FE mounts). This lens should get a real announcement in early fall (September, Sigma says). 

Finally, Sigma finally announced a ship date (April 16th) and price (US$3399) for the Cine 28-105mm t/3 lens, which previously lived as a development announcement.

Voigtlander's Volley at CP+

The 40mm pancake announced earlier in the month wasn't the only quasi-wide Cosina decided to drop. We also get a 35mm f/1.4 Nokton for the Canon RF and Nikon Z mounts. Nothing particularly unique to this muffin-sized lens, but it does line up nicely with the Nikon Zf. 

Zeiss's Zing at CP+

Zeiss announced the missing Otus, the US$2299 manual focus 35mm f/1.4 Otus ML. It will be available for the Canon RF, Nikon Z, and Sony FE mounts. This lens appears to be Zeiss designed, Cosina manufactured. Once again it's a APO Distagon optical design. The published MTFs aren't great at f/1.4 (nor are they at all bad, either), but stopped down this lens looks like an edge-to-edge winner.

——————————

Other CP+ Announcements

▶︎ Panasonic 32-bit float microphone. This US$400 add-on for the Panasonic cameras shows just how much of a value the built-in audio functions on the Nikon ZR really are. The new Panasonic DMX-DMS1 adds a no cables (but kludgy) option that provides 32-bit float, directional pickup control, and a fair amount of tweaking (e.g. wind noise suppression). It's a nice option, but I prefer built-in, as it keeps the camera more gimbal friendly.

▶︎  Canon shows waist level. Looking a bit like a modernized Hasselblad film camera, Canon showed a prototype of a camera with a waist-level viewfinder. Surprisingly, the actual optical path is a "folded DSLR." You're looking down at the focus screen, but during exposure a mirror pops out above the screen to divert the optical path backwards to an image sensor that sits above the lens. I doubt this will show up as a real product, as the look-down form factor is deprecated (motion shows in the wrong direction), and looking down at the viewfinder on modern cameras really only requires a tilting screen ;~).

▶︎ Atomos gets raw. Yes, previous Ninja's can record raw video, but Atomos just announced the 5" Ninja RAW, which records Apple ProRes or ProRes RAW to CFexpress Type B or external USB-C storage. It's been awhile since I used a Ninja, so one thing I should mention is that the RAW and TX Ninja's support Z9 generation cameras (and a few older ones) with "camera control." That includes touch to focus, as well as changing adjusting basic exposure options on the Ninja instead of the camera. At US$700, this new 1500 nit monitor becomes another low cost option for connection to your HDMI port. Just note that it only goes to 6K/30P. If you need 8K/30P you need the more expensive Ninja TX.

▶︎ Where's Pentax? The Ricoh booth at CP+ (owner of Pentax) is all Ricoh. The last Pentax interchangeable lens camera was the K-3 Mark III Monochrome in 2023, which now seems to be discontinued (its image sensor is also used in the Ricoh GR Monochrome, so they probably see the GR as a better use of parts). So now we're down to eight year old K1's and four year old KF's. This "disappearance" is a bit strange to me, as in Japan Ricoh last year gained market share, so you'd think they'd be at the show with some real presence.

-------------------
Wrapping Up

And in other news

▶︎ Droning on in court. China-based DJI this week filed suit in the Ninth Circuit Court of Appeals, claiming that the US violated due process and federal law in failing to assess the security of their products and then banning them. No one, including DJI, it seems, denies that the Secure and Trusted Communications Networks Act of 2019 needed to be implemented in some way. Communications, like people and goods, should respect borders. In 2024 Congress dictated that a security review be done within 12 months. No such review appears to have happened for DJI drones, and in December a broad ban was made covering "all foreign-made uncrewed aircraft and their critical components." 

I get DJI's point here. They offered to open their code and make any changes for any security-related items found problematic. The US government apparently not only didn't respond to that, but simply didn't do any review at all. Because of their use of radio transmission (e.g. Wi-Fi), any new drone sold in the US would need to be registered and approved by the FCC, but we now have a Catch-22: there's no way to do that because a foreign-made product is banned and the FCC won't examine it. This is one of those slippery slope problems. Once you start outright banning one product category, what's to stop you from doing so with others? Indeed, to be logically and ethically consistent, the government should be banning foreign mobile phones and a lot more product types until full security reviews have been passed. But people fear drones, while they don't fear mobile phones ;~). So the government thinks they'll get away with a targeted action.

This drone ban is just more Security Theater from an increasingly incompetent US government. I'm all for security, but I'd prefer my theater to be restricted to playwrights and actors, not government.

▶︎ Your iPhone wants to Safari. Sandmarc added another US$300 telephoto lens to their iPhone 17 lineup, this time a 72mm 3x option. If you can't make it through all the #'s and X's in the optical system, that works out to be 576mm equivalent by the time they're all added up. As with all the Sandmarc add-on lenses, this mounts to the supplied case to insure proper alignment. So, once you take your phone out of its usual case and get this installed, get ready to hold your phone really, really steady.

---------------------

This week's news was early, so next week's news will seem delayed.

Weekly News and Commentary for February 16 to 23

LEDE ON

Who was it that wrote that the Trump-mandated tariffs were unconstitutional and that they wouldn't reduce the trade deficit? Oh wait, that was me, back when the "tariff war" was first declared. Now that the Supreme Court and the full year trade numbers has confirmed what I wrote, much of it looks pretty prescient. Yet it was just applied basic macroeconomics and an actual reading of our Constitution. Of the nine bulleted items I listed would happen, six have become arguably true, the other three are just still arguable.

So now we can expect all the camera makers to reduce their prices and you get issued refunds, right? That's where human behavior takes over from macroeconomic theory. Congress has this way of, once they have your money, not giving it back. Meanwhile, the camera companies didn't see the end of the world after having to raise prices, just a lowering of their profit margins, so what's their motivation to lower prices again? 

Don't get me wrong. I do expect further price adjustments moving forward, but I'll bet those will come mostly in the form of constant and repeated sales rather than the permanent lowering of list prices. I had a boss once whose mantra was "price high, and discount if you have to, because it's near impossible to unilaterally raise prices, but real easy to unilaterally lower them."

Analysis

Taxing Times

You didn't think I'd stop with just the Lede, did you?

We're almost a year after all the original tariff turmoil and guess what, we're back in choppy waters. Let's start with de minimus. That's the part of tariffs that applies to <US$800 items sent directly to customers. Until last year, the idea was to eliminate cost at the Customs department by eliminating the tariff on low-priced items coming in directly to the customer. Then the Trump administration cancelled de minimus and imposed new tariffs by country. While you might think that the Supreme Court threw all that out with their decision last Friday, Trump said that he reinstated tariffs (see also next paragraph). What you probably don't know is that the Big Beautiful Bill that Congress passed last year officially ends de minimus in 2027, so tariff collection will likely start on small overseas purchases regardless of what's happening with the "by edict" Trump tariff declarations.

While the Supreme Court was pretty clear about the way tariffs were declared last year and said, no, that's a Congressional authority, not Executive Branch one, Trump within hours imposed new tariffs, using a different mechanism. Section 122 of the Trade Act of 1974 allows the President to impose up to 15% tariffs for as many as 150 days when there are large trade discrepancies. Trump used that authority to immediately impose 10% tariffs on everything. Then someone in the White House actually read the section in question, realized that they had already agreed to 15% tariffs with a number of companies such as Japan, and the next day Trump said, "oops, I meant 15%." 

So, two things about that: (1) Congress will have to act within 150 days to extend these new 15% tariffs, and that's unlikely in the current environment because it would happen just before the next election; and (2) the reasoning is once again problematic, and will likely get tested by the courts as once again exceeding the authority given by Congress. Section 122 doesn't actually refer to "trade deficit" it refers to "payment deficit", of which the US has very little (the US heavily exports "services", which balances out "trade"). In essence, we have an autocratic regime that can't read and has indicated that they will do what they want and keep trying to find some methodology that might make tariffs stick. In other words, businesses still have no idea what their costs are (and will be), as they keep fluctuating as the tariff battle continues. 

I mentioned before that supposedly one reason for imposing the tariffs in the first place was to reduce the US trade deficit. Other than a brief dip in October, we seem to be pretty much back to "normal" with our physical goods deficit. The only real change that is clearly due to the tariffs is where the goods are being imported from (e.g. not China, though how much of the increase from places such as Vietnam is really just "shuffling" is unclear). We're still paying more for all those goods at the retail side, because, well, someone has to pay the tariffs, and guess what, it isn't who Trump says it is, it's ultimately US consumers.

From the camera maker standpoint, things are back to chaos. Sure, 15% may be less than what they had been paying (or not in several cases). But it's also far less than the previous China tariffs, as well, reintroducing the potential for stronger competition with Chinese lenses again. And, no, no one is going to be reimbursed for unconstitutional tariffs any time soon (if ever), so it's no different than if a parts supplier changed their pricing (and may change it again) and insisted on keeping the money you've already sent them. Note that every camera maker said their profits were reduced by tariffs in their last fiscal year, but that's not going to go away in the foreseeable future.

As much as I've maligned the bean counters in Tokyo in the past, they currently have my sympathy, because they're trying to run their spreadsheets when the inputs keep changing in (mostly) unpredictable ways. Coupled with Japan's 30- and 40-year bond yields now spiking upwards—which has implications on corporate borrowing—the accounting side within all the Japanese camera companies has to be nervous and twitchy at the moment.

For those of you outside the US who probably think that the whole tariff situation doesn't impact you, you'd likely be wrong. With a quarter of sales for companies directly impacted, plus the net impacts of some negotiated deals that have been made, it's probable that pricing is being impacted worldwide, just not nearly as much outside the US as inside. Product decisions are being delayed, as well, because pricing impacts aren't certain. 

My advice to this site's visitors really doesn't change. First, are you sure you need new gear, or are you just a GAS (Gear Acquisition Syndrome) addict? If you need something, then buy on sales if you can or perhaps consider refurbished gear, but don't believe that "things will get cheaper in the future." They might, but that's far less likely at the moment than likely. 

Meanwhile, I'm reminded of a Churchill quote: "We contend that for a nation to try to tax itself into prosperity is like a man standing in a bucket and trying to lift himself up by the handle." Unfortunately, no one seems to be able to pry our leader out of the bucket.

Analysis

I'm Bullish and Bearish on AI

The mainstream media and the big tech companies investing in AI certainly are making loud noises, much like elephants fighting with hyenas. Most of what you hear and what you're afraid of because of those terrible sounds is going to result in a lot of nothing, however. 

The trillions of dollars being invested in server-farm-based, one-company-owned AI systems is not likely to pay back returns. I see distinct parallels to the so-called Web 2.0 run up at the turn of the last century. A lot of cacophony followed by a lot of merrymaking players going poof. 

On the other hand, the serious investment and training of AI models is already paying off big. I, like many of my Silicon Valley friends, run my own LLM (large language module) on my laptop. Yes, I said laptop, and yes, I mean it runs entirely on my laptop. What do I use this for? Sort of as an intern/assistant. While working on my new Web sites, I've had my LLM offer up coding suggestions and verify code, for instance. Sometimes I'll throw an idea at it and see how it responds. But I'm doing the work, I'm just looking at ways to do it more productively. And I can say that it works. Quite well, actually.

If you're a betting person, you can make a bear or bull bet on AI today. 

Meta is a bear bet for me. I see no clear way they can pay back their growing investment in AI, just as I saw no clear way for them to pay back their huge investment in VR. The closest they come to a payoff is the Rayban/Oakley glasses, but because that's an isolated product for them, I don't see it generating the ROI that is needed. Meta's primary source of revenue is selling you advertising on their social media platforms, stet.

Apple is a bull bet for me (and my laptop with the LLM on it is a MacBook Pro). Apple makes hardware, and specifically, they make hardware that takes advantage of technical advances to give users clear new and useful capabilities. While they poke around with centralized AI with Siri, et.al., the real benefit for Apple is if they make hardware that runs AI efficiently and user-useful ways. Which is exactly what is happening and I predict will continue.

What does this have to do with photography? Well, Topaz Labs is an example of them making a bet on my bull side: they want their AI models to run on their centralized servers for which they charge a toll. Frankly, their local model AI (Topaz Sharpen AI, for example), worked more than well enough for me. If anything, they've muddied their models and made them near impossible to use in any productive way, but they'll be happy to sell you use tokens if you want to try using it.

Adobe, meanwhile, is dipping toes in both waters, with both some on-machine modeling as well as centralized. That probably is going to work out okay for them, because, yes, there will be times when my laptop just isn't going to be able to handle some really sophisticated requests and needs a big GPU farm somewhere to do all the computing. 

PetaPixel recently published an article titled "The First Mainstream Manufacturer to Put AI in a Camera Will Regret It," apparently not realizing that all of our current cameras have localized AI models working in their autofocus system (and in other areas, as well). Which gets to part of my point: there's much that AI can help with that's very useful. It can now focus my camera faster and more accurately than I can (though I still override it when it gets it wrong, a much easier process for me to manage). My laptop AI can whip up a Javascript function and test it faster than I can. Adobe Photoshop, both on machine and off, does a better initial selection than I can and does it faster, too. These are the types of AI uses that make sense, and they also often make more sense on local devices (can you imagine your camera waiting for the server to tell it where to focus?). 

Much of the AI hype and fear running around the mainstream media these days is really marketing (and anti-marketing) messaging. Sam Altman is a used car salesman, trying to get you to buy the premium model you don't need. Marc Andreessen is essentially trying to get his investments to make more money, not help you. Elon Musk thinks he can control you by jerking his X controller back and forth. Many of those who helped develop our current AI and LLMs in scholarly venues have cashed in where both high salaries and unrestricted research investments allows them to "live better" both at home and in the lab.

Reality will hit home at some point. It always does with tech. All the promises and gee-whizzing eventually have to have real payoffs for users, or else a lot of (venture) capital disappears in the night. So be careful where you place your bets. New shooter coming out...

CP+ Announcements

Here come the lenses (more in sight)

▶︎  Tamron 35-100mm f/2.8At US$900 (E-mount) and US$930 (Z-mount) this is going to be a popular lens, methinks. The MTFs suggest it is very good out through the DX corners, but the real desired trait is the modest size (4.8" long) and weight (20.3 ounces) for a fast aperture zoom that covers all the standard prime focal lengths (35mm, 50mm, 85mm). This is a lens the Z5II and A7V crowd probably can get behind, even though the initial reviewers all seem a little meh about the focal range. But here's something to chew on: with a Z50II this lens is an effective 53-150mm f/2.8, and appropriately sized. While it's no 50-100mm f/1.8 like the old Sigma DC, it does give a reasonable "fast (not quite) 70-200mm alternative for DX users. To bad it doesn't have VC (stabilization). The curious aspect to this is that Tamron also has a 28-75mm f/2.8 lens, so Tamron is seriously overlapping their own offerings now. 

Along with the lens comes the new, optional Tamron Link accessory, which plugs into the lens' USB-C socket and allows you to control it from your mobile device. This US$50 dongle has a 16' range (Bluetooth) and almost no specifics about it in Tamron's marketing and promotions. So let me explain: using the Tamron Lens Utility app on your smart device and using this new dongle you have quite a bit of control over the lens. This is useful for doing repeatable focus pulls in video, setting precise stopping points for any of the control rings, setting how much rotation of a ring is necessary to get full effect and which direction it goes, switching between linear and non-linear ring responses, jumping between two focus positions, focusing during time-lapse recording, setting precise astrophotography focus positions, setting a focus limiter, and assigning functions to the lens buttons. Videographers are going to like this little tool better than still photographers, but given you can also do firmware updates via the Tamron Link and the Lens Utility app, it's probably worth having for anyone with multiple Tamron lenses.

▶︎  Voigtlander 40mm f/2And if the Tamron is too big and heavy for you (sic), the new Septon from Cosina will attract your attention, as it's a half-pound pancake. Sure, it's manual focus, but with the focusing aids we have these days—including Nikon's MF subject detection—that's not the liability it used to be, particularly for wide angle optics.

▶︎  Nikon 70-200mm f/2.8 VR S II. The second in Nikon's lens remakes for the Z-mount (and not the last), this lens is much like the 24-70mm f/2.8 remake: smaller, significantly lighter, better optically, faster focusing, and with a plethora of small changes that will make you like it more, such as the Arca-Swiss dovetail support on the removable Tripod Collar and the polarizer friendly lens hood. The only thing not to like is the new, higher, US$3199 price. 

▶︎  Nikon 28-75mm f/2.8?. Here's a real curiosity: B&H is listing two versions of this lens (20107 and 20137) at a US$200 price difference, with the higher priced one saying "New Item - Coming Soon."  People are interpreting that as a new version of the lens, but it isn't. The problem is that Nikon had to introduce a new version number based upon the change in country of manufacture (that tariff thing raising its head, again). The only difference between 20107 and 20137 is which country the lens is made in, and Nikon took the opportunity to reprice the lens based upon "current" tariffs. Of course, no sooner did Nikon do that the US changed the Vietnam tariff rate ;~).

And in other news

▶︎ Cage Fighting. SmallRig seems to be fighting with themselves, as they just announced a new HawkLock cage for the ZR. One key difference is that it leaves the top right plate controls completely uninhibited. Another is the V-mount power option that mounts at the back. 

▶︎ WANDRD Unrolls. Their popular PRVKE pack now comes in two non-rollup models, the Zip and the Pocket. No rollup on top, and the Zip has a zippered back pocket, the Pocket has a larger back pocket for "more stuff." These are generally well-made and well-thought out packs, replete with a lot of nice features. The PRVKE now comes in Roll, Zip, and Pocket versions at 21L and 31L sizes. 

▶︎ Feeling Colorful?. Want to test how well you remember a color? Try dialed.gg. Good luck with that. I had difficulty getting above 98.5% correct. But if you think during image processing you're going to dial in the actual color you saw last week, guess what this little game is telling you? ;~) Sure, you've been capturing reality. But which reality is that?

Redesign Update

As you might have noticed, I've not done a lot of posting so far in 2026. That will change in a big way at some point in the future. The question is when, so bear with me.

I've been deep in "design mode" for the past two months, trying to get things figured out in how I approach all of my work, both what you see and what you don't (yet) see. Design mode really is design, test, re-design, test, design some more, test. I've been testing ideas with a few readers, so as to get a better sense of what will really work best for all of us. That's led me to quite a few twists, turns, turnarounds, and different forks in the design process. 

However, I now have a far better idea of how to make everything work the way it should, and work together seamlessly. I've now started locking down design details and populating sites. 

But about that "populating" bit: I've also decided to rewrite (or at least fully re-edit) everything I've written that you see (other than news). As it turns out, that's quite a bit of material. I've now completed that work for filmbodies, am deep in it for bythom, and have begun it for zsystemuser. Once I get a little further along and am sure the designs are locked, I'll offer up the new filmbodies first to get further reactions that might result in a bit more design tuning. Once that is done, bythom will relaunch. And then I'll take a deep dive into zsystemuser, hopefully beating the release of the Z9II ;~). Dslrbodies isn't a particularly active site, so it'll be last in the sequence, probably at the end of the year. 

I'm really liking where all that redesign has taken me. Modern, simple, elegant, clean, high density. 

Just a reiteration: the Web has changed quite a bit in the past decade. My current sites use older technologies and probably won't last through the coming Internet changes. As part of the "new Internet" I've been learning new things, including building a static content management system (CMS) from scratch, then applying Tailwind, Alpine, and Twig to handle complex CSS (when I told my best Silicon Valley friend I was learning Twig, he said "what the heck is that?"). The new sites should respect your device's day/night modes, resize properly with clearer navigation on mobile devices that have small screens, load faster, plus have many other behind-the-scenes improvements. 

If the above weren't enough to do, I wrote three new books in the past two months (one on CMS, not photography), am trying to finish updates on two more, am attempting to finish up yet another new one, and have been stockpiling product reviews to appear when the new sites deploy. I haven't quite felt this engaged in so much since Connectix, where I was managing products for a company that was growing faster than weeds and expected to surprise the world every Macworld Expo. Invigorating.

Wait, you ask, what happened to byThom MAX?

Oh, MAX is coming (one of those books I wrote last month was for it ;~). It actually took me getting main site design fully figured out before I realized exactly what byThom MAX should be and how it will deploy. Moreover, I'm seemingly constantly on the road working on more byThom and byThom MAX content. For example, I'll be at WPPI and NAB in the coming months, meeting with NikonUSA's President, and taking the time to teach some workshops, too. All of which will feed into what I'm up to. Retirement? For wimps. 

Now, if you don't mind, I need to get back to work. 

Weekly News and Commentary for February 1-15

I'm transitioning all of my News/Views into a new format. For the time being, news will continue in this digest form on this site. Enjoy.  (p.s.

LEDE ON

Did the Chinese puncture the Japanese lens tire? The Japanese have a term, attachment rate, which defines how many lenses they sell each year per camera body. The attachment rate was within ±0.02 of an average of 1.67 lenses per body for 11 of the last 20 years. There was an understandable dip in the two post quake/flood years when production was constrained, plus an odd, short upward spike during the pandemic. However, from 2022 to the present there's been a strong and consistent downward trend in the attachment rate: 1.64, 1.61, 1.56, and now 1.51 for 2025. Not coincidentally, the number of prime lenses the Japanese have been selling during that four-year dip has also fallen, and mostly for full frame. Indeed, the drop is more dramatic when only looked at in terms of full frame (a 21% drop in four years). We currently have 55 full-frame Chinese prime lenses that are available for the Nikon Z-mount and even more for the Sony E-mount. While no individual Chinese lens seems to be stealing the attachment rate on its own, collectively the Chinese lens armada is deflating the attachment rate the Japanese camera companies have relied upon for so long. If the ~8% overall decline is really due to Chinese lens sales, that implies that the Chinese sold about 850k units, by the way.

Analysis

Republishing data is not the same as interpreting it

Once CIPA published their year-end results for 2025, it seems that—at least according to virtually every photo Web site—the big news was the resurgence of compact cameras. Yes, compact cameras went from 1.88m units in 2024 to 2.44m units in 2025, but it seems no one actually got around to trying to answer the question of why that happened.

It happened because the Japanese camera makers simply started making them again. The demand was always there (and there's still more demand than the 2025 numbers would indicate, probably something at least in the 3-4m unit range). The real reason compact camera sales withered starting in 2020 and continuing through 2024 has to do with the pandemic and parts availability than anything else. Each camera maker tended to deal with the supply chain problem differently, and the two that were the most extreme at that were Canon and Nikon.

Canon simply stopped making—but did not discontinue—compact models. Thus, you might have noticed in the last year (plus rumors for this year) that some Canon Powershot cameras are seeing resurrections (though not updates). To my knowledge, Canon never closed or repurposed factories the way others did. For instance, Nikon. Nikon did discontinue pretty much everything except for the top Coolpix models (P950, P1100, and for some reason, the P1000 still seems to be sold). There appears to be little prospect of other Coolpix coming back, though the jury is still out on whether Nikon might add a Coolpix model in the future.

Fujifilm had one of their biggest hits with the X100 in 2013, and the 2020 iteration (V) was the point where it really went viral, so they kept their production up despite parts shortages that hurt other model sales. They doubled down with the X-half and GFX100RF in 2025, too, at a time when most of the other camera producers were not investing in new models.

I don't believe the demand for US$1000-2000 compact cameras is anywhere close to being sated, as the Ricoh GRIV and Fujifilm X100VI backorders show (I've got a GRIV I'll be adding to my compact camera reviews soon). But I also believe there's room in the US$500-1000 space for a really competent compact camera, too, and that's not really being well served by anyone at the moment. 

Let me go out on a limb and suggest that compact camera sales will again show dramatic "growth" in volume when the 2026 results eventually get published. How much growth? Not as much as the market demands, as parts shortages are still being triggered by the unavailability of fab time, plus most of the camera companies have made their design teams more lean. But with Canon back to producing Powershots, we'll see more units shipped in 2026 than 2025.

CP+ Announcement

Canon is first to announce

On Wednesday Canon announced two new RF lenses and a reappearance of a Powershot compact in the run-up to the CP+ show later this month in Japan.

▶︎  14mm f/1.4L VCM. This new wide angle optic lists at US$2599 and represents an attempt to lock up the extremely wide, high optical performance prime position before the Chinese start sniping at the RF mount. Some of the early examples from the lens are astrophotography work, so I expect it to be well controlled in terms of coma and other deformities that show up in corners.

▶︎  7-14mm f/2.8-3.5L VCM. And if you want to go more extreme—into the fisheye realm—Canon has a new US$1899 zoom that helps round out their high end zoom optics. At 7mm you get a full circle fisheye (at full frame), while at 14mm you get a 114° rectilinear view.

▶︎  PowerShot G7 X Mark III limited edition anniversary special. This US$1299 compact camera is a 20mp 1" sensor camera with a 24-100mm f/1/8-2.8 equivalent lens. So what do you get for US$400 more than the regular model? A new paint job, a fancier knurled front ring, and a little 30th anniversary (of PowerShot) mark on the pop-up flash.

-------------------
Wrapping Up

And in other news

▶︎ Petapixel isn't an economics site. Once again I have to point out that in their rush to get news out, Petapixel managed to produce clickbait headlines and statements. This time it was "Nikon Posts Big Losses and Cuts Projections." This, of course, always raises the social media negativity towards Nikon Imaging, even though they're not really part of those "big losses," the projection cuts were modest and likely the result of the delayed Z9II, and the group is not in any danger. 

The primary source of those "big losses" for the whole company was a 90.6b yen write down against the acquisition of SLM Solutions to help create Nikon's new digital manufacturing business. Indeed, none of the 103.6b yen loss for the quarter was the result of lack of profitability of Nikon's primary businesses. Cash on hand, receivables, and inventories didn't really drop; what really dropped was 60.5b yen in "goodwill" that was on the books and 26.2b yen in intangible assets. 

What that tells me is that Nikon was over optimistic in how they booked the original SLM acquisition. The write downs are mostly just saying that the 3D metal printer company Nikon bought in 2023 wasn't worth what they paid for it and then booked into their assets. Thus, this past quarter they wrote down their assets to reflect that. The actual cash long ago left the building. FWIW, get ready for a repeat in three months from Petapixel, as Nikon has already said they'll take another significant write down in the fourth quarter (again, none of it having to do with their biggest business, cameras and lenses). 

In the fiscal news that is important to the photography market, Nikon Imaging is showing signs of a slowdown in sales (part of Petapixel's "cuts projections"). Foreign exchange rates and tariffs coupled with the fact that Nikon volume shifted to lower priced models due to recent camera updates is the real story. Overall, that means that Nikon is estimating that they'll still reach the same total sales figure by March 31st as they earlier forecast, but it will produce less profit by about a third. Since Nikon is also forecasting 50k fewer cameras and 100k fewer lenses, for sales to hit their new expected fiscal year result they need to sell more higher end gear and not give back more money via foreign exchange and tariffs. What that suggests to me is fewer sales on lower end gear and more on higher end products. 

I do note that Nikon is going to slip slightly in market share for the year, but as I've already reported, the next generation of top end cameras has been delayed, and that's now starting to show up in the results. I believe Nikon originally thought that they'd drop the Z9II towards the end of their fiscal year (i.e. this quarter), which produced their original estimates. I do not expect the Z9II until this fall (in Nikon's next fiscal year) at this point, and even then it may be a development announcement first, followed by frantic testing to get it out as quickly as possible. 

Nikon Imaging is fine. Not quite where management hoped it to be, but actually still on the path of the long-range forecast they made several years ago. But as I've written several times lately, early 2026 is going to mostly be about lenses, as I see no new Nikon camera ready to to hit any time soon. Frankly, that's fine by me as I'm still trying to catch up with the Z9 generation onslaught Nikon made in the past few years.

▶︎ Godox keeps it going. The perennial Chinese flash cloner has introduced the V1mid, a reasonably small round-headed US$179 flash unit with a built-in Li-ion battery. As usual, there's fairly full functionality (including hi-speed sync) with Canon, Fujifilm, Nikon, OMDS, and Sony specific models available. Also as usual, Godox refuses to publish Guide Number information, which is useful in determining which flash unit you might actually want. In fact, there are a number of "unprovided" notations in their specifications, as if this is top secret information that could fall into the wrong hands. All we know is that the V1mid is not as powerful as the V1. I guess the dox in Godox doesn't stand for documentation. 

▶︎ Next week will get busy. The CP+ announcements start in earnest this coming week, so expect to see a lot more news and commentary coming shortly. 

------------

As you can see, this weekly or bi-weekly "newsletter" style for News/Views can be quite elaborate and lengthy. But by putting everything in one spot less often, in a single format, it saves me time and allows me to spend more time on the commentary than the news itself, which you can get pretty much anywhere.

byThom MAX is still coming, but for the time being I'll be doing news this way. I'll have more about byThom Max when I kick it off later in 2026. In the meantime, if you're interested in subscribing, click here to receive updates.

Where Are We?

Another month has ticked by, and while it may look like the camera companies and I took the month off, nothing can be further from the truth. 

Let's start with the camera companies. Nikon and Sony are waiting for chips (or perhaps just starting to get final chips and now working frantically to do final firmware work). I really don't expect any new cameras from either any time soon, though both have a number of lenses pending. Fujifilm and Canon seem to be targeting CP+ for their next camera announcements, so basically "later this month." OMDS and Panasonic seem pretty opaque at the moment to whatever it is they're up to. Leica is rumored to be sold. 

From a GAS (gear acquisition syndrome) standpoint, the first half of this year seems like it will be mostly about lenses, with scattered cameras. 

Here in the frigid Mid-Atlantic, I've been pretty much bolted to my desk between bouts of snow shoveling, ice removal, and occasional grocery store visits. My Priorities List seems to have grown to novel length, but I'm finally managing to shorten it rather than add to it. I wrote two books in January while working on three others. Technically, I wrote a third book, but it isn't on photography, so you don't care ;~). Since you haven't seen any of that work, you might guess that some of it has something to do with byThom Max (you'd be right). Meanwhile, I've been working on new designs for four sites, and am only really waiting for a final software update from the vendor whose product I'm using before I start the first deployment. 

On top of that, I developed intro and outro bits for upcoming videos, started a new project on getting my computer storage updated (including new name conforming), cleaned out the old office to recycle a bunch of gear, and much more.

Reviews? Well, they seem to be as frozen as the landscape at the moment. Oh, I've done the lab work, I'm just waiting for a few days where I won't freeze my hands to the products trying to get a few additional images to look at. It doesn't help that my usual long-distance diagonal reference spot is basically just a panorama of white at the moment. White snow in focus kind of looks like white snow with spherical aberrations, if you get my drift (pardon the pun). 

So bear with me (and the camera companies). We're all deeply at work, it's just not a time when you're going to see a lot of evidence of that. But come the thaw...

LEDE ON

CES supposedly stands for Consumer Electronic Show, and last week we just had that annual extravaganza. Curiously missing were cameras. Unlike many previous years, we saw no new photography-related product launches from Canon, Nikon, or Sony. Nikon didn’t even have a booth. Curious about this, I decided to look up what CTA, the association that runs the show says about what things are covered at CES. Sure enough, no mention of imaging. Video is mentioned, but not Imaging. I guess we consumers have moved on from Imaging. Not so consumer topics such as AgTech, Quantum, and Space Tech seem to have been added. Not that anything particularly interesting came out of this year’s CES. Unless you consider things like adding AI to Catepillar tractors interesting. I guess we’re stuck with our 4K televisions and current cameras now.

Explainer

Triple Stacked Sensors

You’re probably seeing articles that mention triple stacked image sensors, specificallly in relation to Apple and Samsung. You may think that might mean something akin to the Foveon sensor, where three layers of silicon are examined to find (near) R, G, and B values for a single pixel. It doesn’t.

Triple stacked refers to PD-TR-Logic. The top-most portion (PD) is the photon detection and converstion to charge. The second portion (TR) is transport. This is still a bit of a nebulous concept as in the patents we see different definitions of what this layer can/should do. In its simplest form, it’s simply moving the charge out of the PD layer. Technically, a simple “stacked image sensor” as we have in Sony and Nikon cameras has a transfer layer in it, though this is at the moment it is merely connections between two independently created layers. In more complex forms that are being considered, TR is actually a communication portal between the PD and Logic layers. For instance, Nikon has demonstrated image sensors that let the logic layer to make changes to how the PD layer operates in 16x16 pixel blocks, though this sensor has not appeared in production yet.

The Logic layer is what it sounds like: this is where you start doing computational things with the data moving downwards in the stacks. 

Many of the early posts about future Apple/Samsung chips make non-sensical claims about “better than Sony Exmor.” I’m sure that we’ll get image sensors in the future—all this triple stack discussion is about the future—that are better than past image sensors. However, the commentators making such claims also don’t seem to understand where current Exmor lives. The partial stacked sensors now coming out of Sony Semiconductor are actually a side idea of the thing driving straight triple stack: let the PD do its job, have on-chip methods of moving that data as fast as possible into the partial stack, which is essentially a logic addition melded to the basic image sensor via a unique method that Nikon Precision seems to have originated. It’s not stacked behind the PD layer, it’s mounted as a partial layer on top.

Two somewhat competing things are happening with traditional image sensor development at the moment. The first is the pursuit of bandwidth: speed up everything that happens post the actual photon conversion (starts with TR layer). The second is the pursuit of control/computation (logic layer). What’s driving this is not still photography (we don’t reallly need full image data at >30 fps), it’s autofocus and video. Current top cameras are sub-sampling focus streams at 120 fps, while video is pushing so much data now (e.g. 8K/60P) that rolling shutter becomes an issue due to bandwidth constraints. 

Basically, image sensors haven’t been changing much in the PD section, which is one reason why you don’t see a lot of movement in dynamic range. But we have seen changes at the “edge” of PD, such as the dual gain output in the partial-stacked image sensors, which combine a second ADC read with faster bandwidth to get that data. As long as we stick to the traditional Bayer-type PD use, it’s the things that happen post photon conversion that will change. 

One of the most likely scenarios for a full triple stack sensor is that it will apply AI noise reduction to the data before it gets to the image processing stream. But other possibilities exist, as well. 

The bottom line is: we aren’t quite there yet, but we can see where we might want to go.

Commentary

Be careful what you think...

I continue to have to do cleanup for other sites.

▶︎  “Image Sensor With 26 Stops of Dynamic Range” Technology is very difficult to keep up with and fully understand. What tends to happen when the media doesn’t fully understand a new technology, they simply repeat marketing messages. Canon showed off a new SPAD (Single Photon Avalanche Diode) image sensor at CES, along with the claim of 156db dynamic range (which most sites did the conversion on and reported as 26 stops). We have two things to explain here:

Current image sensors collect photons over time (effectively shutter speed) and then count how many they receive. We refer to that as PD (Photo Diode). A SPAD sensor reacts every time it receives a single photon, so rather than collect photons—actually convert photons to electrons—internally in the sensor, the downstream electronics have to assemble the counts. The good news about SPAD is that it doesn’t have electronic read noise at the sensor, effectively an “avalanche” is a 1 and “no avalanche” is a 0. This absolutely improves data integrity in really low light, as only signal should be recorded.

However, the thing that the media never quite picks up on is this: photons are random. For the past decade our PD image sensors have been pretty darned good at recording the randomness of photons. Yes, there’s electronic noise in the lowest level of the signal, but as Nikon demonstrated more than two decades ago, three basic noise components exist, at with any technology one of them will dominate. We are in an era where randomness of photons is the dominate producer of noise. So however good Canon’s new SPAD is in low light data integrity, will all the extra dynamic range actually show up in photos? Not in the ways that 26 stops (versus or current 11-12 stops) suggests or the mainstream media intimates. 

This is not to suggest that we won’t get single photon detection at some point in our cameras. Both Canon’s SPAD efforts and Fossum’s JOT designs are almost certainly going to be in our cameras at some point. But neither is going to remove the randomness of photons, so the overall impact in low light will be different than you think: not so much a noise reduction (randomness stays random), but more an improvement in data integrity. As most of you know, my mantra is “optimal data capture, processed optimally,” so I’m all for SPAD and JOT.

Wrapping Up

And in other news

▶︎ Shapeshifter Shifts, Keeps Shape. ThinkTank Photo introduced two new Shapeshifter bags, the 25L and 37L. The basic premise of these bags is to avoid dividers and have you put everything in pouches (several pouches are supplied with each bag). This isn't the first time we've seen pouches in their bags. The two basic problems with this idea are: (1) you're almost certainly going to end up buying more pouches if your kit has to morph for different work, and (2) it's more cumbersome to get things out of and back into pouches when you're changing gear quickly, particularly if you use the drawstrings on the pouches to try to keep dust and other elements away from your gear. I tried the first pouch backpack ThinkTank Photo made (disclaimer: it was provided for potential review free of charge), but ultimately felt that the system was just not flexible enough. It's not clear that the new versions will be more flexible.

Those of you who've encountered me during travel will know that I use bags with dividers. However, while in transit I put all my individual gear components into really thin bags and slide those into the dividers. The reason for this is two-fold: modest protection from the elements and those dreaded Frankfurt "empty your bag" requests at their security posts. 

▶︎ Apple goes subscription. In a bit of odd news, Apple announced a new Creator Studio product, which is really just a bundle of existing products coupled with some AI additions, available as a subscription. The standalone products will still be available as perpetual purchases, however now there's a new extended subscription option. The implication is that the perpetual products will go into near feature stasis, while the subscription versions will get extended more. Creator Studio includes Final Cut Pro, Logic Pro, Pixelmator Pro, Motion, Compressor, and Main Stage with along with "substantial AI features" for those products as well as Pages, Numbers, and Keynote. Price will be US$12.99/month, or US$129/year when they appear on January 28th (there's a one month free trial). Particularly telling is the offer to students and educators: US$2.99/month, or US$29.99/year. Given that it would take multiple years before either cost comes close to equalling what you pay for all the perpetual products, it seems well worth the cost to someone coming new into Mac and iPad content creation, particularly students. What's unclear at present is whether those of us who own those products already would really get any real value from the "substantial AI features." Those features are locked if you don't have a subscription.

As you can see, this weekly or bi-weekly "newsletter" style for News/Views can be quite elaborate and lengthy. But by putting everything in one spot less often, in a single format, it saves me time and allows me to spend more time on the commentary than the news itself, which you can get pretty much anywhere.

byThom MAX is still coming, but for the time being I'll be doing news this way. I'll have more about byThom Max when I kick it off later in 2026. In the meantime, if you're interested in subscribing, click here to receive updates.
