Leitz Canada Elmarit-R 135mm f2.8 (3 cam) brand_Mamiya Super comfortable and in greatThe Leitz Canada Elmarit R 135mm f2. 8 (3 cam) is a good quality short telephoto lens for Leica R mount. Smooth focusing, clean glass, minor cosmetic wear. The built in retractable lens hood works well and should be on every lens, in my opinion. This 3 cam lens is compatible with any Leica R mount camera.
