This was back up to my RZ, so rarely used, hard to find a mark on it, photos show condition. Recently tested with photo shoot and everything works great and film looked just right. Lens glass, mirror, and prism all very clean and clear. Note how this is the rare amazing 80mm f/1.9 lens for film in low light situations and ease of focusing.
Later production lens has the front in Black like this instead of earlier that had chrome on the front part of the lens.
