Nikon NIKKOR Ai-s 200mm f/4.0 Prime Lens Nikon F-mount manual focus This is a 200mm prime lens. I purchased it over 20 years ago and have stored it unused since then. There are many fine scratches. There is some dust inside the lens. I have sold my Nikon camera, so I cannot guarantee the image quality. This lens is for those seeking the nostalgic feel of film cameras. Includes front and rear caps. Thank you for looking.
