The Silver Edition HD PENTAX-D FA* 50mm f/1.4 SDM AW from Pentax, part of the company's Star Series of lenses, 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. Autofocus is powered by Pentax's Ultrasonic Motor SDM, providing fast and accurate focus while shooting. Additionally, the rounded 9-blade diaphragm produces smooth bokeh for portraits or other types of shots. This lens is also weather sealed, ensuring consistent performance during adverse outdoor shooting conditions.
