    Overview

    The SMC Pentax-A 15 mm f/3.5 is a manual-focus ultra-wide-angle lens for Pentax K-mount. Optically, it offers good sharpness in the center but significant corner softness and distortion, typical of its era. Build quality is solid with a metal barrel and smooth focusing, but the lens lacks autofocus and modern coatings. It suits photographers who need an affordable ultra-wide for film or digital and are comfortable with manual operation and post-processing corrections.
