The FA 50mm f/1.4 SDM AW Lens from Pentax is a standard length prime lens with a bright maximum aperture that enables accurate low-light shooting as well as providing a wide range of depth of field control. While designed for full-frame Pentax K-mount cameras, the lens can be used on APS-C format cameras where it provides a 76.5mm focal length. Aero Bright Coating II and HD Coating on the 15 lens elements reduces flare and ghosting even when shooting in harsh lighting, and a front element SP Coating repels water and fingerprints from affecting the front of your lens. .
