Versatile Standard-Length Prime. The Pentax HD FA 50mm f/1.4 SDM AW’s focal length makes it great for a broad range of applications. Its large maximum aperture provides brightness and clarity that’s ideal for portraiture and indoor photography. Its rounded nine-blade diaphragm renders images with beautiful, natural bokeh. Using an APS-C camera? This lens will give you a 76.5mm equivalent focal length.
Ultrasonic Motor Autofocus. The ultrasonic motor offers fast, smooth, and nearly silent autofocus performance, while the Quick-Shift Focus System gives you full-time manual focusing for quick adjustment.
Premium, High-Quality Optics. This lens’s fifteen-element/nine-group optical design includes an extra-low dispersion glass element and three fluorite elements that minimize flare and ghosting, even in harsh lighting conditions. Pentax’s HD coatings reduce reflections and lens flare, and Super Protect coatings on the front and rear elements repel dust, water, and oils.
All-Weather Build. The 50mm features eight distinct seals to shield against the elements, and the included lens hood helps to eliminate lens flare.
