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

[John McMaster]

I can send you links to a rough comparison of S2 /Mamiya 300mm f2.8 APO (with and without 2x) compared to R9/DMR with 280mm f4 APO (1993 model, with and without 1.4x APO), I may take another look at the adapter but I now have Leica S 180mm as well as the Mamiya...

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.
