Overview

The HD Pentax-FA 31mm F1.8 Limited is a compact, all-metal lens praised for its build quality and tactile feel. Optically, it delivers sharp images with smooth bokeh and a pleasing 3D effect, though it is not environmentally sealed and has a permanent hood that some find cumbersome. Its unique 31mm focal length offers versatility, but the lens shows its age against modern optics. It suits Pentax enthusiasts seeking a well-crafted, character-rich prime for APS-C or full-frame.
