Made of black anodized aluminium (camera body mount) and brass silver (lens mount). The adapter allows Cannon Zoom lens EF to be used on four third system camera body such as Olympus E-1, E-300, E-500, E-330, E-400, E-410, E-510, E-3, E-420, E-520, E-30, E-620, E-450, E-600, Panasonic Lumix DMC-L1, DMC-L10 & Leica Digilux 3 etc.
Although the lens will fit physically, automatic diaphragm (AE metering), or any other functions are not retained using this adapter. In this case you will need to meter in "stop-down mode" since the lens does not have the ability to have its aperture controlled by the camera body. NOTE: The adapter does not support any Canon FD lenses. Focus can not be infinity with prime lenses, a photographic lens whose focal length is fixed.
