    Overview

    The SMC Pentax-FA 50mm f/1.7 is a compact autofocus lens with plastic build that suits early Pentax AF cameras. Optically, it is very sharp wide open and holds its own against more expensive options like the Sigma 50mm f/1.4, with no notable flare issues. Some users report a unique, painterly look on film, though it has flaws and is far from perfect. It offers excellent value, typically priced between $50 and $150, and is recommended for Pentax AF users seeking an affordable, capable 50mm.
