[Leica] Lei-ko R lens to S body adapter ring

[Charlie Chan]

Hi Doug,

OK, I never realised that the focussing pitch caged from 3 cam to ROM. My copy is indeed an older 3 cam version S/N 36589XX, manufactured 1994.

The rumoured 350 S lens may well not happen. Focus is manual of course with stop down metering. The max focus distance is limited, unless you send the lenses to Leica for adjustment.

My newer copy (ROM) focuses only slightly past infinity and even has a different focussing pitch.  Sounds like the older version is a better fit for the S2 + lei-ko adapter.
