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

[Charlie Chan]

Good news. Just to say that I have just tried my 3 cam 280/4 with the 1.4x APO converter - infinity focus is ok!!! Am a very happy bunny.

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.
