Key Features
IN-CAMERA SHAKE REDUCTION (SR): The PENTAX digital SLR K series cameras are equipped with the SR mechanism built into the camera body. Because shake reduction is applied in the camera body, this means that any lens compatible with the K-Series cameras will benefit from image stabilization.
PENTAX STAR SERIES LENS: A new-generation, high-performance Star-series lens delivering superb imaging quality and exceptional resolving power.
HIGH IMAGE QUALITY: By using three super ED glass lens and aspherical lens elements, a clear image is achieved with less chromatic aberration. Thanks to the 12 elements, sharp images are captured even at the edges at any given focal length.
HD COATING TO ENHANCE IMAGING POWER: Produce high-contrast images with edge-to-edge sharpness and free of flare and ghost images.
NEWLY DEVELOPED RING-TYPE ULTRASONIC WAVE MOTOR SDM: Generating a torque approximately 1.3 times that of the unit installed in the HD PENTAX-D FA50mm f1.4 SDM AW, this new SDM assures flawless, high-speed autofocus operation.
ALL WEATHER (AW): This lens features a dependable dustproof, weather-resistant structure to prevent the intrusion of water and dust into the lens interior.
ROUNDED DIAPHRAGM: Nine-blade, round-shaped diaphragm to produce a natural, beautiful bokeh (defocus) effect up to an aperture of F2.8.
SUPER PROTECT COATING: PENTAX-original SP coating uses fluorine treatment on the front surface of the lens. This prevents adhesion of dust, water drops, grease and other substances.
KAF4 MOUNT: This lens features a KAF4 lens mount compatible with an electromagnetic diaphragm control system. Cameras compatible with this system are K-1 Mark II, K-1, K-3 II, KP, K-70, K-3, K-S2, K-S1 and K-50. For K-1, K-3 II, K-3, K-S2, K-S1 and K-50, the camera’s firmware must be upgraded to the latest version.
