D800 AF is based on D4
please explain what is better in 5dmk3 and how you can make a statement like this
This is the first time I have seen a serious claim that the D800 AF is equal or better than the 5D MkIII AF.
Roger Cicala of lensrentals tested and found that the Canon's phase detection AF is as accurate and consistent as its contrast detection AF, i.e. the standard deviation of MTF values of a series of static shots is the same for both AF systems. This is a remarkable achievement. The D800, 'nope'. It is just not as reliable on phase detection.
And that is with static subjects.
He also says there is a left side AF sensor issue with the D800 that is unresolved, and recommends the camera only be used for centre point AF. I hope THAT isn't 'based on the D4'!
