And because I was in extremely low light, the camera had a hard time focusing-- it kept hunting, and I missed lots of shots. "Man, the real weak point of the 5DII has always been autofocus. It just doesn't work half the time."
As if on cue, Canon announced the 5D Mark III today. The two biggest changes seem to be that it has a 61-point autofocus system (as compared to the 9-point one on the Mark II) and the ISO range has been expanded to 25600 native (as opposed to 3200 on the Mark II.) I swear that Canon was listening in on my conversation last weekend.
It would be wildly irresponsible for me to fork over this much cash right now, but oh man do I want one.
