Asahi SMC Pentax-M 1:1.7 50mm (PK) [3244689]

Second-hand PK mount prime lens 50mm in good condition, clean, no scratches. Provides stellar image quality at a wide range of apertures. The 1.7 maximum aperture opening makes it a great portrait lens. Only defect worth mentioning here is that the last group is showing the beginning of lens separation, which has no impact on the working of the lens.
