Strange, that. It would seemingly have nothing to do with the cam and
RF; rather, with variances in mount-to-filmplane distance, which I would
think Leitz would make to very close tolerances (using shims, etc.).
Leitz had no problem with using M lenses on the CL (except the wides
that would foul the metercell arm); so if CL lenses won't inf. focus on
Ms, then M lenses wouldn't on CLs either, nicht?
