I was at the Southwestern Photojournalism Conference in Fort Worth over the weekend. The Canon reps had a 1D MKIII on hand. I don't have much to say (as I didn't spend much time with the camera). The camera feels just as robust as a MkII, but the "set" button in the middle of the scroll wheel just seems out of place. I'm sure it'll feel more natural once I start using it a bit more. The shutter sounds pretty similar. Maybe just a hair quieter (I didn't pay much attention though). The shutter movement? Fast, of course. Anybody else gotten a hand on it?
