This Leica 500mm f8 MR-Telyt-R Mirror Lens, #3139160, is in great condition with minor handling wear. I rate it cosmetically a (9+). The focus ring is a bit stiff, but the aperture functions properly and 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. This lens includes front & rear caps.
