Nine-blade, round-shaped diaphragm to produce a natural, beautiful bokeh (defocus) effect up to the F2.8 aperture setting, while minimizing the streaking effect of point light sources
Exterior design that facilitates focus-ring operation in manual-focus shooting and provides a firm hold
Electromagnetic diaphragm-control mechanism* for flawless, high-precision exposure control during video recording
SP (Super Protect) coating to keep the front surface free of dust and spots
A large-aperture, medium-telephoto lens for use
with K-mount digital SLR cameras
In order to assure the exceptional imaging power demanded in the new-generation, high-performance Star series, this new lens incorporates high-grade Super ED (Extra-low Dispersion) glass optical elements and an aspherical optical element to compensate various aberrations to a minimum — in particular, to effectively minimize axial chromatic aberration to prevent the generation of purple fringing in backlit situations. It also reduces distortion — a serious concern in portrait photography — to nearly zero at a focusing distance of four meters. In addition, PENTAX has developed a new ring-type SDM exclusively for this new lens to realize flawless, high-speed autofocus operation, while adopting an exterior design providing a firm grip to facilitate manual-focus operation. This new lens is designed not only to assure the highest imaging power currently possible, but also to optimize the joy of picture-taking.
Main Features
New-generation, high-performance Star-series lens to deliver ideal image quality. Anticipating the further advancement of SLR camera bodies in the future, PENTAX has designed this lens to deliver extra-clear, high-contrast images with edge-to-edge sharpness by compensating various aberrations to a minimum, while greatly enhancing resolving power — two factors absolutely essential in the next-generation Star series. It provides exceptionally high imaging performance even at open aperture, a beautiful bokeh (defocus) effect and outstanding image rendition at close ranges — all reasons why it produces high-quality, well-defined images. It also boasts an extra-large F1.4 maximum aperture, useful with many different subjects in a range of applications, including portraiture with an effectively defocused background, handheld shooting of indoor scenes and scenic photography. It helps the camera to produce a bright, clear viewfinder image that will inspire the photographer’s creativity and imagination.
State-of-the-art optical technology. This lens incorporates three Super ED (Extra-low Dispersion) glass optical elements to effectively minimize chromatic aberration, and a glass-molded aspherical optical element to effectively compensate for spherical and comatic aberrations and field curvature to deliver extra-clear, high-contrast images with edge-to-edge sharpness, even at open aperture. It also reduces distortion to nearly zero at a focusing distance of four meters to deliver well-defined, distortion-free images over the entire focusing range, from the minimum focusing distance to infinity. This lens is also treated with high-grade, multi-layer HD* Coating, which reduces average reflectance in the visible ray spectrum to less than 50% of conventional multi-layer coatings, effectively reducing flare and ghost images to a minimum even in demanding lighting conditions such as back-lighting.
Dustproof, weather-resistant construction.
Developed as an AW (All Weather) model, this lens features a dependable
dustproof, weather-resistant construction with eight special seals to prevent
the intrusion of water into the lens barrel. When paired with a dustproof,
weather-resistant PENTAX digital SLR camera body, it assures a durable,
reliable digital imaging system that performs superbly in demanding shooting
settings — even in rain or mist, or at locations prone to water splashes or
spray.
Exclusively designed, large ring-type SDM. In order to deliver the highest image quality possible over the entire focusing range — from the minimum focusing distance to infinity — this lens features an exclusively designed, large ring-type SDM to efficiently drive the focusing mechanism, which consists of a larger number of optical elements than ordinary lenses, and is required to shift heavy rear-optical-element groups in unison. Generating a torque approximately 1.3 times that of the unit installed in the HD PENTAX-D FA★ 50mm F1.4 SDM AW, this new SDM assures flawless, high-speed autofocus operation.
