This week I borrowed an instructor D800 from New York Film Academy (where I teach) and did a bit of testing with it. This shot was taken at f/2.8 using a Nikon 24-70mm zoom. Normally I prefer to shoot with a prime lens, but we have yet to get some of those in our equipment cage. Overall, I'm really happy with what I've seen: the files are incredibly sharp and I've had no issues with digital aberrations. I'm seriously considering upgrading from my current camera, the D700.
