A focus shift at max. aperture isn't really possible by definition. In this case you've "just" a back-/front-focus problem.

That said it can be calibrated this way on purpose assuming that it hides the worst at smaller apertures.

Yes, I know that. It is just a figure of speech. <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/sad.gif' class='bbc_emoticon' alt='Sad' /> But the fact remains that calibration was not successful for all distances and all AF points.



Happy shooting,

Yakim.
