AF in DSLRs can work just fine with most lenses, and then you have a lens which does not give accurately focussed results, and you then blame it on an "offset between sensor and actual AF sensor"? How does that compute?

 

There are three things that make for occasional AF accuracy issues with PD AF in DSLRs.

...
Well, of course there is 4th reason: mechanical tolerances in case of separate AF sensor, as with DSLR. Which are quite complex due to 3 parts getting into optical path for AF aquisition: main mirror, secondary mirror and AF sensor itself.
