Consumer Lens Adapter, Leica M Lens to Micro 4/3 (MFT) System Camera Lens Mount Adapter\n\nHave an old lens you wish you could use with your swanky new camera? With the Fotodiox Pro adapters, you now can. Fotodiox Pro offers a wide-range of adapters from large format to small format digital adapters. Using the larger format lens to smaller format sensors provides edge-to-edge sharpness. The smaller image field helps minimize the effects of lens distortion and abnormalities by using the “sweet spot” (or center) of the larger lens image circle.\n\nMade with high-standard precision, the all-metal design and polished surface is designed to guarantee a smooth mounting surface and a long-lasting experience.\nThe specific adapter allows the Leica M lenses to be used with the MFT camera. The adapter will work with both breech-lock mounts and bayonet-lock mounts\n\nAlthough 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. You can shoot with manual mode or aperture priority mode micro 4/3 body. Infinity focusing is guaranteed.
