This is a Canon single-focal-length lens. It was made around 1955-56. Unlike recent lenses, it's made only of metal and glass, and has a very solid and luxurious feel, similar to a Leica Summarex. It has been stored in a dehumidified storage unit when not in use after purchase. Rangefinder operation has been confirmed on a Leica 'M10'. The exterior has some dirt, but both the aperture and focus rings move smoothly. There are some fine scratches like wiping marks on the rear element, and some marks on the edge, but there is no balsam separation, and it seems to be in good condition. I don't think it will affect the photos. This is a subjective assessment, so please refrain from purchasing if you are overly concerned. Please make your judgment based on the photos. ・Mount: L39 (screw mount) ・Maximum aperture: f/1.8 ・Focal length: 50mm ・Aperture blades: 10 Included items ・Lens body ・Kenko UV filter (as a bonus, with wiping scratches) ・Canon genuine metal lens cap (as a bonus) ・Rear cap (as a bonus) ● Please check my profile before commenting or purchasing to ensure a smooth transaction. ● Please understand that this is for personal use and personal storage before purchasing. ● No claims and no returns are accepted.
