Allowing you to mount a Leica R lens to an SL (Typ 601) mirrorless digital camera, the R-Adapter L allows you to breathe life into legacy glass. This adapter maintains infinity focus and the adapted lens' focal length, and also supports the camera's use of aperture-priority metering, as well as manual exposure mode. It is solely compatible with the SL (Typ 601) camera along with 43 select R lenses manufactured after 1976.
