Leica's fast M-mount 28mm f/2 — Summicron quality with 6-bit coding for digital M bodies.
The Leica Summicron-M 28mm f/2 ASPH. (6 bit) is a wide-angle prime for the Leica M rangefinder system at Summicron (f/2) aperture class. ASPH. = aspherical element. 6-bit coded for electronic communication with Leica M digital bodies. Full-frame. Leica M mount.
f/2 maximum aperture. 28mm focal length (full-frame). ASPH. aspherical element. 6-bit lens coding. Manual focus with rangefinder coupling. At approximately 270g. 46mm filter thread. Leica M mount.
The 6-bit coding communicates lens data to M digital bodies (M8, M9, M Typ 240 onwards) for EXIF metadata and in-camera lens profile correction in post. Summicron-M 28mm ASPH. is Leica's fastest 28mm M-mount prime at f/2. Compact and light relative to the wider 21mm primes. A useful focal length for street and travel reportage on M.
On the used market the Leica Summicron-M 28mm f/2 ASPH. (6 bit) is a premium wide prime for Leica M cameras. Condition checks: 46mm front element for marks, focus ring damping, rangefinder coupling accuracy, 6-bit coding contacts condition. Leica M mount — manual focus. Check frameline compatibility with your specific M body.
