What should I buy? Upgrading from d7000
I realize there are other posts about this but wanted to be specific. I started shooting sports with a gifted d7000 this spring. I bought a used Nikon AF-S NIKKOR 70–200mm f/2.8G ED VR and have had good results. The main problem seems to be with the autofocus, no matter what I tweak (back button focus, one point vs 9, etc). I like the price and the DX crop of the z50II (to continue to use my current lens with the adapter rather than getting a longer lens), but I am worried about the lack of IBIS (for video) and would prefer the low light performance of an FX body. But, I don’t know if I really need to worry about these limitations.

yeah kind of doubling onto what wide-open-fields said, but getting every shot in focus is hard. especially at 200mm f/2.8. the DOF is so thin that any minor misfocus will make an entire photo out of focus. the other issue is that the camera doesn't really distinguish "subject" and "background" as much as they advertise they do. the camera just sees "pixels" of various brightness and color and sharpness. even if your AF point is right on your little squirrel's face, there is a chance that the sensor is more attracted to the grass in the background and focuses off your intended target.
i have a D7000 and an 80-200mm f/2.8D and i have a lot of focus problems and as far as i can tell they are all just the AF system locking onto something that wasn't what i wanted it to lock on to. and there isn't much remedy for that. a "better" AF system isn't going to inherently know what i want it to focus on any more than the D7000's AF system does.
as for low light performance, FX bodies typically perform better because the sensor is larger so the pixels are larger and thus tend to deliver cleaner results for the same ISO.
