SecureGSM said:If your body is 1Dx then you won’t run into major AF issues with sigma Art lenses. 1DxII owners would beg to differ though. 5D III is only slightly affected but not as bad as 5DIV bodies.
My 85A is consistent on the 1dx2. Same AFMA number as the 5DsR. Focus shift is the only problem But it's just one lens, it won't make much statistics.
