For Canon FD Mount lens to Leica M Mount adapter. Made of aluminium and brass. Focus to infinity. With lock & stop pin. Manual control, manual focus and manual exposure. Although the lens will fit physically, automatic diaphragm, auto-focusing, or any other functions will not operate correctly while using this adapter. In this case "stop-down mode" will need to be used when metering since the lens does not have the ability to have its aperture controlled by the camera body.
