High ISO - 7D or 1D MkIII?
I currently shoot with a 7D but have become increasingly disappointed with my high ISO (800-1600) results. I'm considering picking up a low mileage 1D MkIII because I've heard that I'll get less noise in that ISO range than the 7D. I realize that we're talking about technology that's now quite a few years old but would like to get some opinions... Unfortunately I just cannot afford a 1D MkIV right now...
Thanks!
7D is slightly better when focal-length-limited
I wrote a paper on this a few years back...

As Roger has pointed out, in a focal-length-limited scenario where you cannot move closer to the subject you are shooting, the 7D has better resolution and roughly the same noise level. This only applies to a focal-length-limited scenario however. (But, that's usually the scenario for a bird photogapher.)
