Nippon Kogaku Nikkor-Q 135mm F4 This is an extremely rare lens with very limited availability. There are no options, and it is tentatively listed as F-mount, but it is NOT F-mount. This is a bellows-only lens. By combining it with a bellows like the Nikon PB-3 (around 5000 yen used), you can take pictures from infinity to close-up. Condition: Slight haze: None Mold: Slight The optical condition is quite clear, I think. The aperture blades are also clean. Please feel free to comment with any price inquiries! *The condition is based on my subjective assessment. *It is an old item, so it is not in perfect condition. *Returns are not accepted.
