The Novoflex Lem/Cont Adapter allows a Contax SLR type lens to be mounted unto a Leica M type camera.
Although the lens will fit physically, automatic diaphragm (AE metering), or any other functions are not retained using this adapter. In this case the user 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.
