And if, by any chance, this combo requires calibration, who's going
to be happy to do it? Sigma or Canon?

Do you speak about front focus/back focus ?

I am test lens yesterday. We shot ruler on table from camera with angel of 45 degree. With diaphragm 1.2. And focusing at the beginning of ball point pen.

And then look on depth of field of the ruler on image. Perfect! It was that i want.
