Description The NOVOFLEX A-Mount to Leica M Body Adapter (short version) from NOVOFLEX allows a NOVOFLEX Universal Bellows to be mounted to a Leica M mirrorless cameras. Although the bellows 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. No rangefinder coupling! Please use a Leica M-camera with Live View-Mode.
