Use your Leica M-mount lenses on a Sony E-Mount camera with this TTArtisan M-E 6Bit II Adapter, which enables you to communicate EXIF data between the camera body and the lens. For M-mount lenses without 6 bit contacts, the adapter features a click ring to set the correct focal length on the camera. The body of the adapter itself is crafted out of lightweight aluminum and has an interior lined with anti-reflective coating. On the lower left side, a reset button can be used to ensure that the adapter is working correctly after changing lenses.
