Leica 90mm f/2.5 SUMMARIT-M, Telephoto Manual Focus Lens for M System (Black). The Summarit-M lenses are designed to offer traditional Leica optical and mechanical excellence while positioned at a price level below the current M ASPH lenses. The aim of these lenses is to bring classic Leica quality and performance to a broader market of users. The Summarit-M maximum aperture of f/2.5 and the concentration on classical and proven spherical lens designs leads to very compact, but high performance lenses with excellent quality expected from a Leica lens. The Summarit-M lenses will see the reemergence of traditional Leica elements. All letter and number engravings will be made using the traditional "Leitz-Norm" font as originally used by Leitz Wetzlar during the 1960's and the red button onthe lens mount will be true to the original color used on lenses produced since the introduction of the M mount through the 1970's. Includes Metal Front Cap, Rear Cap, Cloth Lens Pouch and Leica Two-Year Warranty. Vendor Part # 11646
