Leitz Tele-Elmar 135mm f4 lens mount_Mamiya 7 which provides a fair bitThe Leitz Tele Elmar 135mm f4 is a telephoto lens for the Leica M mount. Kind of an awkward focal length to use with a rangefinder, not gonna lie, but quality is excellent. Just back from a complete CLA and in excellent condition, with minor cosmetic wear, smooth focusing, and clean glass. Includes rear and (non original) front cap.
