This Nikon AI-S 20mm f3.5 Nikkor Lens, #217658, is in good condition with some handling wear. I rate it cosmetically an (8+). The aperture ring is smooth, but the focus ring is quite stiff. 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.
