why micro focus adjustment not in the camera ?

Granted, I rushed things a bit, I apologize, my fault - and this issue is a bit confusing: however, the point I think you missed is that the AF mechanism in the body should bypass all these tolerances, as it measures only the light coming in from the lens.

And: if there is a problem with the distances the two light beams (to the ST mirror and the APC-snsensor) cover insdie the body, the camera body must be adjusted. However, people in this forum talk about the lens getting calibrated. That would not eliminate a mirror / sensor distance problem.
