Pentax HD Pentax-D FA 85mm f/1.4 ED SDM AW Lens with Free PC Software & Acc Kit

When it comes to capturing stunning, high-contrast images with edge-to-edge sharpness, the HD Pentax-D FA 85mm F1.4 ED SDM AW Lens from Ricoh Imaging is a top-tier choice. This advanced, large-aperture, medium-telephoto lens is a proud member of the new-generation Pentax Star lens series, specifically designed for use with Pentax K-mount digital SLR cameras. This innovative lens boasts the highest imaging performance across all Pentax lens lineups, thanks to its high-grade Super ED (Extra-low Dispersion) glass optical elements and an aspherical optical element. These features, combined with a multi-layer HD Coating and a newly designed, large ring-type SDM, ensure the delivery of extra-clear images by effectively minimizing various aberrations, including axial chromatic aberration. This results in the prevention of purple fringing in backlit situations, providing you with flawless, high-speed autofocus operation and exceptional imaging power.The HD Pentax-D FA 85mm F1.4 ED SDM AW Lens is renowned for its high imaging performance even at open aperture, producing a beautiful bokeh (defocus) effect and outstanding image rendition at close ranges. The extra-large F1.4 maximum aperture is versatile and ideal for various subjects and applications, including portraiture with a defocused background, handheld shooting of indoor scenes, and scenic photography.State-of-the-art optical technology is at the heart of this lens. It incorporates three Super ED glass optical elements to effectively minimize chromatic aberration, a glass-molded aspherical optical element to compensate for spherical and comatic aberrations, and field curvature. This lens also reduces distortion to nearly zero at a focusing distance of four meters, delivering well-defined, distortion-free images over the entire focusing range. The lens is 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. This effectively minimizes flare and ghost images even in demanding lighting conditions such as backlighting.The lens features a newly designed, large ring-type SDM to efficiently drive the focusing mechanism, which consists of a larger number of optical elements than ordinary lenses. This new SDM assures flawless, high-speed autofocus operation.As an All Weather (AW) model, this lens boasts a dependable dustproof, weather-resistant structure with eight special seals to prevent water intrusion. When paired with a Pentax dustproof, weather-resistant digital SLR camera body, it forms a durable, reliable digital imaging system that performs superbly in demanding outdoor shooting settings.The lens also features a nine-blade, round-shaped diaphragm that produces a natural, beautiful bokeh effect up to the F2.8 aperture setting, while minimizing the streaking effect of point light sources. An electromagnetic diaphragm control mechanism provides high-precision exposure control during video recording. The Quick-Shift Focus System allows for instant switching from auto-focus to manual-focus operation. Lastly, the lens is treated with a Super Protect (SP) Coating on the front surface to effectively repel water and grease, ensuring your lens stays clean and ready for action.
