Developed as the latest addition to PENTAX's acclaimed Star-series, this new high-performance lens is designed to deliver extra-clear, high-contrast images with edge-to-edge sharpness. Anticipating future advancements in SLR camera bodies, PENTAX has equipped this lens with state-of-the-art optical technology to compensate for various aberrations, greatly enhancing its resolving power - two key factors essential for the next-generation Star series.

Thanks to the incorporation of three Super ED (Extra-low Dispersion) glass elements and a glass-molded aspherical element, this lens is able to effectively minimize chromatic aberration, spherical and comatic aberrations, as well as field curvature, even when shot at the maximum F1.4 aperture. The result is exceptionally high imaging performance, with a beautiful, natural bokeh effect and outstanding image rendition, even at close focusing distances.

To ensure flawless, high-speed autofocus operation across the entire focusing range, this lens features a newly designed, large ring-type Supersonic Direct-drive Motor (SDM). Generating approximately 1.3 times the torque of the unit used in the HD PENTAX-D FA 50mm f/1.4 SDM AW lens, this advanced SDM mechanism efficiently drives the focusing mechanism, which consists of a larger number of optical elements compared to ordinary lenses.

Developed as an AW (All Weather) model, this lens boasts a dependable dustproof, weather-resistant construction with eight special seals to prevent the intrusion of water and dust into the lens barrel. When paired with a compatible PENTAX digital SLR camera body, it delivers a durable, reliable imaging system capable of superb performance even in challenging outdoor conditions.

Additional features include a nine-blade, round-shaped diaphragm to produce a natural, beautiful bokeh effect up to the F2.8 aperture setting, while minimizing the streaking effect of point light sources. The lens also benefits from PENTAX's SP (Super Protect) coating, which helps to keep the front surface free of dust and spots.

Offering an extra-large F1.4 maximum aperture, this versatile lens is useful for a wide range of subjects and applications, including portraiture with an effectively defocused background, handheld shooting of indoor scenes, and scenic photography. The bright, clear viewfinder image it produces will also inspire the photographer's creativity and imagination.

In summary, the new PENTAX Star-series lens delivers uncompromising image quality and exceptional resolving power, making it an essential tool for discerning photographers seeking the highest level of photographic performance.
