Leitz Tele-Elmar 135mm f4 brand_Tokyo Kogaku 3/8" fitting in the baseThe 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. Minor cosmetic wear, smooth focusing, and clean glass with only minor dust.
