Fine finishing made with high standard precision. The adapter is made of black anodized aluminium (camera body mount) and brass silver (lens mount). It allows the use of Leica R lens on Micro Four Thirds system body such as OLYMPUS E-P1,E-P2, E-PL1, Panasonic G10, G2, G1, GH1, GF1, G1-HD etc.. Although the lens will fit physically, auto-focusing and aperture control through the camera are not retained. Focus to infinite is available. Note: 99% or more of all Leica mount R lenses are probably compatible with the adapter and camera.
