The Leica M Lens to Micro Four Thirds Body Lens Mount Adapter from NOVOFLEX allows a Leica M lens to be mounted to a Micro Four Thirds mirrorless camera. 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.
Due to the construction of the Leica M bayonet, not correctable imaging errors may appear during longer exposure times.
