• Front side - C-mount female thread
• Rear side - Leica L-mount

Machined from high quality aluminium alloy.

This adapter allows using C-mount lenses on camera with Leica L-mount. Infinity focus preserved.

This version of the adapter has a side rim that provides a good grip for fingers for easy installation/removal. The drawback is a bit worse access to a lens control ring (some C-mount lenses have an aperture control ring very close to the mount).
