This Pentax SMC (super multi-coated) 50mm f2 Prime would have been an original option on the P3/30 and Program A / Program Plus bodies. It’s light and well built.
Condition: This copy is in really good condition mechanically, with smooth focus and fast aperture action. Very little wear on the handling surfaces. No fungus or haze visible, and some light individual dust particles seen when a bright inspection light is used but image quality is not affected.
