  • The HD PENTAX-D FA★50mm F1.4 SDM AW lens delivers exceptional resolving power from the centre to the edges of the image field, even when set to open aperture. The lens incorporates state-of-the-art PENTAX-developed lens coating technologies - including the new Aero Bright Coating II for exceptionally low reflectance and high-grade high-definition (HD) Coating - that enable it to produce extra-sharp, high-contrast images free of flare and ghost images. The lens's dustproof, weather-resistant body also makes it extremely dependable and durable for shooting in demanding outdoor conditions. Its PENTAX K-mount covers the image circle of a 35mm-format full-frame image sensor.
  • New-generation, high-performance Star-series lens with large F1.4 maximum aperture:
  • This lens has been developed as a new-generation member of the high-performance Star series - a lineup designed to deliver extra-clear, high-contrast images with edge-to-edge sharpness while keeping aberrations to a minimum. The lens, which is the result of an extensive review of traditional Star-series standards, provides greatly improved resolving power, which enables it to deliver excellent imaging performance even with more advanced, next-generation camera bodies. Developed as the first model of the new-generation Star-series lenses, the new lens boasts an extra-large F1.4 maximum aperture, useful with many different subjects in a range of applications, including portraiture with an effectively de-focused (bokeh) background, and hand-held shooting of indoor scenes. It provides exceptional image quality even at open aperture, as well as outstanding performance at close ranges.
  • State-of-the-art optical technology:
  • The lens is treated with PENTAX-developed Aero Bright Coating II ? a lens coating developed using a state-of-the-art nanotechnology process. It consists of a silica aerogel layer with a uniform porous structure over a regular multi-coating layer that reduces surface reflections across a wide wavelength range and produces crisp, high-quality images.
  • By coupling this advanced lens coating with the high-grade, multi-layer HD (high definition) Coating, average reflectance in the visible ray spectrum is reduced to less than 50% compared to conventional multi-layer coatings. As a result, the lens effectively reduces flare and minimizes ghost images even in demanding lighting conditions, such as backlighting. The lens incorporates three super-low dispersion glass elements and one aspherical element to effectively compensate for chromatic and spherical aberrations, enabling it to produce brilliant, high-contrast images with edge-to-edge sharpness. Since distortion is minimized even at a focusing distance of approximately one metre, the lens produces crisp, distortion-free images over the entire focusing range, from the minimum focusing distance to infinity.
  • Dustproof, weather-resistant construction:
  • Developed as an AW (all weather) model, this lens features a dependable dustproof, weather-resistant body with eight special seals to prevent the intrusion of water and dust into the lens interior. When paired with a PENTAX weather-resistant digital SLR camera body, it forms a durable, reliable digital imaging system that performs superbly in demanding conditions ? even in rain or mist, or at locations prone to water splashes or spray.
  • Newly developed ring-type motor:
  • This lens features a newly developed ring-type SDM (supersonic direct-drive motor), which generates as much as 7.5 times the torque as the SDM installed in previous-generation lenses. This enormous driving power assures a smooth, high-speed shift of the heavy, multi-element rear lens group during focusing operation.
  • Other features:
  • Nine-blade, round-shaped diaphragm produces a natural-looking de-focus (bokeh) effect up to an F2.8 aperture setting, while minimizing the streaking effect of point light sources
  • A minimum focusing distance of 0.4 meters, effective for capturing images with a de-focus effect
  • Electromagnetic diaphragm-control mechanism,* for flawless, high-precision exposure control during movie recording
  • SP (Super Protect) coating to keep the front surface free of dust and spots
  • * This mechanism is available when the lens is mounted on a PENTAX K-1 Mark II, K-1, K-3 II, K-3, KP, K-70, K-S2 or K-S1 camera body.
