A Large-Aperture, Medium-Telephoto Lens for Use With K-Mount Digital SLR Cameras

In developing the new generation of the top-of-the-line Star series, PENTAX conducted an extensive review of its in-house standards, demanding the most satisfying performance even for use with future PENTAX digital SLRs, which are expected to deliver higher image quality and better performance than current models. Developed in pursuit of ideal image quality, this new lens delivers superb imaging power, without relying heavily on the image sensor or image processer. It lets the photographer enjoy the entire picture-taking process by checking the subject in detail and in real time via a sharp, clear image produced by its high-grade optical viewfinder.

Exceptional image quality

Pentax has designed this lens to produce extra-clear, high-contrast images with edge-to-edge sharpness whilst keeping various aberrations to a minimum and greatly enhancing resolving power.

The lens provides exceptionally high imaging performance and a beautiful bokeh effect thanks to its impressive F1.4 maximum aperture which is useful for portraiture with a beautifully defocused background, handheld shooting of indoor scenes and landscape photography.

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-moulded aspherical optical element to effectively compensate for spherical and chromatic aberrations and field curvature to deliver extra-clear, high-contrast images with edge-to-edge sharpness, even when the aperture is wide open. 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 backlighting.

Newly designed, large SDM ring

In order to deliver the highest image quality possible over the entire focusing range — from the minimum focusing distance to infinity — this lens features a newly designed, large SDM ring to efficiently drive the focusing mechanism, which consists of a higher 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.

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.
