The strange thing is that it's not constant. Sometimes better, sometimes worse. And, my auto focus lenses all work more or less perfectly!
If you have encountered this problem, and know why it's happening, I would appreciate hearing from you. I am not really upset, since I won't be using manual focus lenses much on the 1D III, but I am a bit disappointed.
