The Leica 75mm f/2.0 APO Summicron M Aspherical lens is a fast high-performance lens that is also extremely compact.
With its more natural perspective compared to a 90mm focal length, it is ideally suited for many applications including reportage and portraits - particularly in smaller rooms. Its small dimensions result in not only outstanding handling but also a Leica M viewfinder image that is almost completely free of shadowing, thus allowing totally undisturbed viewing of the subject.
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).
Optical improvements include: an aspherical surface, glass with anomalous partial dispersion and a high refractive index, a floating element including a brand new, high-precision adjusting mechanism, lens coating, and sophisticated measures to reduce internal reflection
Floating element maintains the outstanding imaging performance even at the minimum range of 2.3' (0.7 m)
Built-in lens hood can be locked in its extended position to prevent it from accidentally being pushed back in
Includes "6-bit code" which allows the digital M8 camera to identify which lens is being used, and also to store this information in image metadata
