To attach R Lenses to M-series Digital Camera
This R-Adapter-M from Leica lets you mount Leica R lenses on any M-series digital camera. It is compatible with the M-E or M Monochrom, however with the M Digital Rangefinder's Live View capability, use of the R lenses is optimised. There are no electronic or mechanical functions between the camera and lens, however, when the adapter is attached to the M camera, a list of 20 dedicated R lens profiles is made available on the camera, including EXIF lens recognition and calibrated imaging workflows for each lens. While all R lenses can be mounted to the M camera with this adapter, only the last generation of R lenses can receive digital corrections, such as the reduction of corner vignetting, via the adapter.
