Astute readers will have already noticed that I have posted my D3 review and Complete Guide page. Nikon's two major firmware updates and some issues that I had to resolve with whether my sample was doing something different than others made these things painfully slow to finish, as I had to go back and do all my tests twice more, then test other D3 bodies. Nikon has a habit of sneaking in unknown changes at firmware updates. Indeed, if you've got a D300 you should probably already have noted that there appear to be two unannounced differences with the latest firmware for that camera. First, the 14-bit hesitation seems to have been either removed or lowered significantly. Second, there seem to be improvements to autofocus tracking of some motions; I notice this especially in 51-point.
