So the saga continues... they adjusted "a microscopic amount of decentering" of my 200 f2 so it's perfect, but the original issue remains. The took 350 dollars for the adjustment that basically did nothing.
But they told me something interesting, each af point can be adjusted in a 3D matrix for each individual lens, so they need to move the left side af points forwards for them to work with the camera. So the 1dx is shipped today to hopefully get my stuff to work.
My questions are, how can this be only with ONE lens out of a hundred, most with extremely thin dof, and how come I have never had this issue with any body lens combo the last 12 years? And how come the lens behaves exactly the same with my brothers 1dx and not with a single other lens on his camera? And what happens if I buy another body? Do I have to keep paying to adjust the bodies to this one lens "that is optically 100% perfect" ??
