This adapter allows use of LTM lenses (39mm Leica mount thread) on the M-mount bodies.
The adapter is made in Japan, great finish and workmanship. It is made of brass with chrome plating. Some surfaces are left unplated (polished brass), so the camera mount will not be marked or scratched in any way. You can see this on the image. The adapter comes with a spanner wrench to make its installation easier.
The adapter is available in 3 variations. Each one will enable certain frame in your camera's viewfinder. Please consult the chart below and select the version you need from the Available Options pull-down menu.
The Jupiter-8 lens is shown for illustration only and is not included.
