This Leica 9cm f4 Elmar Lens (Black), #517147, is in fair condition with heavy handling wear. I rate it cosmetically a (7+). The aperture ring is extremely stiff, but the aperture functions properly. The glass is clean and clear with no haze, marks, or fungus. There are a few faint specks of dust inside, but they do not affect image quality. The focusing helicoid is quite stiff. This lens is for Leica screw mount/thread mount (LTM) and other E39 bodies. It includes a rear cap, but no front cap.
