Who may be able to help me with my Canon 5D III, it's been to Foto Maerz in Berlin twice, to Okam in Zwenkau and to Canon Germany, Krefeld, it still has an autofocus error, but only Maerz is seeing it and told me they have no clue what to do. It's so critical that I'm only using the camera's center focus point for the last 15.000 images instead of relying on it's "sophisticated" 61-point auto mode. And I don't really know what to do ...

This is the reference image ...

This is what I get using center point (needs calibration, too, it's not spot on) ...

But this is what I get using its auto mode ...

Any help appreciated!
