5D mkII contra 5D mkIII
I am happy to edit this passage with correct information:
"that 5D mkII is slower and less accurate than the "newer" 5D MKIII. Also it´s taking slightly less sharp Pictures due to a sensor with lower resolution allthough the overall diffrence in image quality isn't significant at low ISOs. At high ISOs, the Mark III is much better. The autofocus system on the Mark III is much, much improved, although the 5D Mark II is a great old warhorse and will take excellent pictures in competant hands."
