TTArtisan LEICA M TO E 6-BIT Adapter Ring

The TTArtisan M-E 6-bit adapter ring let you use your Leica M lenses on a Sony E mount camera, translate the 6-bit codes on Leica M lenses to Sony lens exif. If you use a lens without a 6-bit code you can also set one of the typical Leica M focal lengths (28/35/50/75/90/135) via a small wheel.
