SMC Pentax-F 50mm f1.7 tube and only very minor cosmeticThe SMC Pentax F 50mm f1. 7 is a compact standard lens for Pentax K mount cameras, with autofocus linkage for cameras with focus motors in the body. Naturally, this lens can also be focused manually on older K mount cameras. In excellent condition, with minor cosmetic wear, most notably initials engraved on the extending barrel; there's no effect on function, as you might imagine. Glass is clean, focus and diaphragm move well.
