SMC Pentax-F 50mm f1.7 brand_Bilora This sturdy all-metal arm hasThe 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.

Glass is clean, focus and diaphragm move well.
