$(document). ready(function() { SampleGalleryV2({"containerId":"embeddedSampleGallery_6820557164","galleryId":"6820557164","isEmbeddedWidget":true,"selectedImageIndex":0,"isMobile":false}) }); Just two weeks after Ricoh revealed more details of its long-teased portrait prime, the HD Pentax-D FA* 85mm F1.
4 ED SDM AW has officially been released. The new lens offers numerous special elements, a new AF motor and the build quality we've come to expect from high-end Pentax lenses.
The 85mm F1. 4 contains a total of 12 elements, including 'Super ED' and aspherical glass. An HD coating is used to reduce flare and ghosting. The lens has a new ring-type SDM lens motor to drive the focusing elements, which delivers 1. 3x more torque than the motor on the 50mm F1. 4, according to Ricoh. The lens has a nine-blade aperture that is electronically controlled.
Minimum focus distance is 0. 85m (2. 8ft) and the maximum magnification is 0. 12x. It's sealed against dust and moisture in eight places (that's the 'AW' designation - standing for 'All Weather') and can be used in tough conditions when paired with a weather-resistant Pentax camera.
The FA* 85mm F1. 4 will be available in mid-June for $1899.
Press release:
Ricoh announces HD PENTAX-D FA
Second fixed focal-length model added to next-generation, high-performance Star lens series
PARSIPPANY, NJ, May 27, 2020 nce of all PENTAX lens lineups.
PENTAX developed a new, ring-type SDM (Supersonic Direct-drive Motor) exclusively for this new lens to enable flawless, high-speed autofocus operation, with an exterior design that assures a firm grip for manual-focus operation. The HD PENTAX-D FA
The new lens incorporates three Super ED (Extra-low Dispersion) glass optical elements to effectively minimize chromatic aberration, and a glass-molded 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 at open aperture. This design 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.
The HD PENTAX-D FAwfinder image that will surely inspire photographic creativity and imagination.
Developed as an AW (All Weather) model, the new lens features 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.

The HD PENTAX-D FA
Main Features of the new HD PENTAX-D FA
1. New-generation, high-performance Star-series lens to deliver ideal image quality
Anticipating the further advancement of SLR camera bodies in the future, PENTAX has designed this lens to deliver extra-clear, high-contrast images with edge-to-edge sharpness by compensating various aberrations to a minimum, while greatly enhancing resolving power — two factors absolutely essential in the next-generation Star series. It provides exceptionally high imaging performance even at open aperture, a beautiful bokeh (defocus) effect and outstanding image rendition at close ranges — all reasons why it produces high-quality, well-defined images. It also boasts an extra-large F1. 4 maximum aperture, useful with many different subjects in a range of applications, including portraiture with an effectively defocused background, handheld shooting of indoor scenes and scenic photography. It helps the camera to produce a bright, clear viewfinder image that will inspire the photographer’s creativity and imagination.
2. 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-molded 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 at open aperture. 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 High-Definition (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.
3. Newly designed, large ring-type SDM
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 ring-type SDM to efficiently drive the focusing mechanism, which consists of a larger number of optical elements than ordinary lenses, and is required to shift heavy rear-optical-element groups in uniso
4. 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 conditions — even in rain or mist, or at locations prone to water splashes or spray.
5. Other features
Nine-blade, round-shaped diaphragm to produce a natural, beautiful bokeh (defocus) effect up to the F2. 8 aperture setting, while minimizing the streaking effect of point light sources
Exterior design that facilitates focus-ring operation in manual-focus shooting and provides a firm hold
Electromagnetic diaphragm-control mechanism** for flawless, high-precision exposure control during video 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 K-1 Mark II, K-1, K-3 II, K-3, KP,
K-70, K-50, K-S2 or K-S1 camera body.
