Wow, the ISO 1600 of the 5D3 is more detailed and less noisy than the ISO 400 of the 5D2 for all tests and ditto for ISO 3200 shots Vs 800 ones for the two bodies! Oh, really? :-o
Once again, it's time for me this pity guy to save my money for a new 5D3! ;-D And, the measurbations will never end! :-(
