Is there really a difference that can be seen by the human eye? I am buying a new camera, $ really isnt an issue, but I currently use 2 5d's and have NO problems and love the full frame with my L lenses. The question is a new Mark IIds with the 16.7 full frame, or the new mark III 10.2 with the 1.3. Speed is NOT an issue, I have never run into a situation with my 5d's 3 or 4fps rate where I said "man I wish it was just a little faster" so the big issue for me is picture quality, will I really tell a big difference between the 10.2 14bit, vs the 16.7 12bit? thanks.
