Leica Telephoto 90mm f/2.0 APO Summicron M Aspherical Manual Focus Lens (6-Bit, Updated for Digital) - Black

A fast, newly computed high-performance lens for portraiture and photojournalism. Also excellent for quick snapshots when you want to take pictures inconspicuously from a distance. Its high speed permits relatively fast shutter speeds that prevent blurred images caused by camera motion. With an aspherical lens element and Apochromatic correction, this lens sets new standards in the category of short telephoto lenses. Built-in sliding lens hood.

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).
