I can see a back focus on the left side picture with the 70-200, and what he should have done is take a series of 10 on both the left and right side to confirm the difference. That would rule out random error of the AF sensors. That is the only real thing he should have done to make his judgement more solid. Other than that, his pictures show more information pointing at a left af sensors issue than the opposite.

And compare those shots against CDAF focussed shots taken in Live view. That would unambiguously rule out any lens issues.

You can still have lens issues that affect PDAF but are overcome by CDAF

My opinions are my own and not those of DPR or its administration. They carry no 'special' value (except to me and Lacie of course)
