While our mirrorless and DSLR cameras these days pretty much all have video capabilities, "Hollywood"—I'm using a really broad brush here—tends to march to a different drummer.
The 52 feature films presented at the 2021 Cannes Film Festival break out like this:
- 41 taken with Arri cameras
- 14 taken with Sony cameras (only 2 of which were not dedicated video cameras, both of those were A7S)
- 5 taken with Canon cameras (all dedicated video cameras)
- 4 taken with RED cameras
- 1 taken with an iPhone
- 1 taken with a Panasonic S1H
- 1 each taken with three other video cameras
Numbers don't add up to 52 because some films used multiple cameras.
So, of the 52 features, three primarily used mirrorless still/video crossover cameras (A7S, S1H). Dedicated video cameras still dominate, even in the documentary categories.
Which brings me to a bit of ironic news: the Nikon Zfc has dropped the word "movie" from its menu naming: it's now the VIDEO SHOOTING menu and not the MOVIE SHOOTING menu. Other "movie" references are also now "video." It's about time. The use of the term movie was a bit pretentious considering that Nikon's inroads into the actual movie business have been declining so rapidly as to be nearly non-existent.
