Pentax Super Multi Coated Macro Takumar 50mm f4 M42 mount lens body M42 close-up ring intermediate ring set of 3 Front cap Rear cap I used this lens on a SONY camera for digitizing film. The aperture was previously stiff, so I had a professional disassemble and clean it. It now operates smoothly. The focus ring works. There is some slight haze due to age, but it does not affect normal shooting. Using the intermediate rings allows for life-size (1:1) photography.
