Extremely compact and light-weight, the Leica 28mm f/2.8 Elmarit-M Aspherical Lens is currently the most compact lens in the line-up of Leica M-system lenses. This lens is practically distortion-free in the whole focus range from 2.3" (0.7 m) to infinity and only extends slightly into the viewfinder field of M cameras.
This lens has been updated with the "6-bit" coding, which allows the digital M camera to read this information optically and to identify which lens is being used. The camera can then (optionally) apply a "final stage" software based vignetting correction (for RAW images the lens used is simply recorded, no change is made).
