Genuine Leica M-Adapter L 18765 Silver This adapter allows you to mount Leica M lenses on Leica L mount cameras. I recently purchased this used at a camera store. The lens mount shows some slight wear, but the exterior appears to be clean with no scratches. I tested it with a Leica SL, and it functioned without any problems. I am selling it because I no longer need it. It's cheaper than a new one, so please consider it. No box, only the adapter and front/rear caps.
