The Pentax FA 50mm f/1.4 SDM AW Lens, a member of the esteemed Star Series, is a standard prime lens characterized by its bright maximum aperture, which facilitates precise low-light photography and offers extensive depth of field control. Although it is primarily designed for full-frame Pentax K-mount cameras, it is also compatible with APS-C format cameras, where it effectively provides a focal length equivalent to 76.5mm.
The lens features Aero Bright Coating II and HD Coating across its 15 elements, significantly minimizing flare and ghosting, even in challenging lighting conditions. Additionally, the front element is treated with SP Coating to resist water and fingerprints, preserving the clarity of the lens. Autofocus is driven by Pentax's Ultrasonic Motor SDM, ensuring rapid and precise focusing capabilities.
