This adapter allows you to use your R mount lenses on the Leica SL, T, and TL. With the R-Adapter L, you can now bring your perfectly ground and polished, elaborately coated, R-Lenses back into use. They benefit from the modern technology of the Leica SL and achieve new heights of performance. Leica R-Adapter L Bringing a whole new life to valuable Leica equipment, the Leica SL is compatible with all Leica R-Lenses from the past, thanks to two Leica adapters specially developed for the mirrorless system. The Leica R-Adapter L supports all Leica R-Lenses with a ROM module and contacts, and automatically detects the profile of each lens. This solution provides compatibility with the majority of R-Lenses manufactured after 1976. An alternative option caters for R-Lenses without ROM or those built before 1976: combining an M-Adapter L with an R-Adapter M provides a solution that is compatible with all Leica R-Lenses ever built. The lens profile can be selected from the list of lenses within the camera menu.
