Leica M39 to Leica M lens adapter

Description:

This lens mount adapter allows a Leica Visoflex lens (M39) to fit on a Leica
M camera body. Although the lens will fit physically, automatic diaphragm, auto-focusing,
or any other functions will not operate correctly while using this adapter.
In this case "stop-down mode" will need for shooting since the lens
does not have the ability to have its aperture controlled by the camera body.
Infinity focusing is guaranteed.
