The adapter allows Leica R mount lens to be used on any Samsung NX camera. The adapter is manual and camera modes which control exposure by automatically adjusting aperture are not available. Infinite focus is guarantee. Note: 99% or more of all Leica mount R lenses are probably compatible with the adapter and camera.
