PENTAX has designed this new-generation, high-performance Star-series lens to deliver exceptional imaging quality and resolving power, anticipating future advancements in SLR camera bodies. By compensating for various aberrations to a minimum, the lens provides extra-clear, high-contrast images with edge-to-edge sharpness. It boasts an impressive F1.4 maximum aperture, making it versatile for portraiture, indoor handheld shooting, and scenic photography.

Featuring state-of-the-art optical technology, this lens incorporates three Super ED (Extra-low Dispersion) glass elements and a glass-molded aspherical element. This effectively minimizes chromatic aberration, spherical and comatic aberrations, and field curvature, resulting in distortion-free, high-contrast images with edge-to-edge sharpness, even at the open aperture. The lens is also treated with high-grade, multi-layer HD Coating, which reduces average reflectance in the visible spectrum to less than 50% of conventional coatings, effectively reducing flare and ghosting.

To deliver the highest image quality across the entire focusing range, from minimum to infinity, the lens features a newly designed, large ring-type SDM (Supersonic Direct-drive Motor). Generating 1.3 times the torque of the unit in the HD PENTAX-D FA50mm f1.4 SDM AW, this new SDM ensures flawless, high-speed autofocus operation.

Developed as an AW (All Weather) model, this lens is equipped with a dependable dustproof, weather-resistant construction, featuring eight special seals to prevent water intrusion. When paired with a compatible PENTAX digital SLR camera body, it forms a durable, reliable imaging system that performs superbly even in challenging shooting conditions, such as rain or mist.

Other notable features include a nine-blade, round-shaped diaphragm that produces a natural, beautiful bokeh effect up to F2.8, while minimizing the streaking effect of point light sources. The exterior design facilitates smooth focus-ring operation during manual focus, and the lens is equipped with an electromagnetic diaphragm-control mechanism for precise exposure control during video recording.

Additionally, the lens features PENTAX's SP (Super Protect) coating on the front surface, which helps keep it free of dust and spots. This mechanism is available when the lens is mounted on select PENTAX K-series camera bodies, which are also equipped with in-camera shake reduction (SR) functionality, providing image stabilization for any compatible lens.

In summary, this new PENTAX Star-series lens delivers exceptional imaging performance, with advanced optical and mechanical technologies that ensure high-quality, well-defined images in a wide range of photographic applications, even in demanding shooting conditions.
