Apparently Konica got it right on the "Konica M" lenses. I believe the back focus problem is caused when the cumulative plus / minus parts tolerances on a particular body add up beyond Leica M specs. this would explain why some bodies have problems, and others don't. Judging from user comments it seems to be an infrequent problem, but that does not make it nonexistent.
