Pentax HD PENTAX-D FA★85mmF1.4ED Lente telefoto principal SDM Lente serie Star de nueva generación Últimas tecnologías de recubrimiento de lentes PENTAX Imágenes extra nítidas y de alto contraste, libres de destellos y imágenes fantasma
- Marca: Pentax
- Código de Producto: B088ZTJ7VV
-IN-CAMERA SHAKE REDUCTION (SR): The PENTAX digital SLR K series cameras are equipped with the SR mechanism built into the camera body. Because shake reduction is applied in the camera body, this means that any lens compatible with the K-Series cameras will benefit from image stabilization.
-PENTAX STAR SERIES LENS: A new-generation, high-performance Star-series lens delivering superb imaging quality and exceptional resolving power.
-HIGH IMAGE QUALITY: By using three super ED glass lens and aspherical lens elements, a clear image is achieved with less chromatic aberration. Thanks to the 12 elements, sharp images are captured even at the edges at any given focal length.
-HD COATING TO ENHANCE IMAGING POWER: Produce high-contrast images with edge-to-edge sharpness and free of flare and ghost images.
-NEWLY DEVELOPED RING-TYPE ULTRASONIC WAVE MOTOR SDM: Generating a torque approximately 1.3 times that of the unit installed in the HD PENTAX-D FA50mm f1.4 SDM AW, this new SDM assures flawless, high-speed autofocus operation.
-ALL WEATHER (AW): This lens features a dependable dustproof, weather-resistant structure to prevent the intrusion of water and dust into the lens interior.
-ROUNDED DIAPHRAGM: Nine-blade, round-shaped diaphragm to produce a natural, beautiful bokeh (defocus) effect up to an aperture of F2.8.
-SUPER PROTECT COATING: PENTAX-original SP coating uses fluorine treatment on the front surface of the lens. This prevents adhesion of dust, water drops, grease and other substances.
-KAF4 MOUNT: This lens features a KAF4 lens mount compatible with an electromagnetic diaphragm control system. Cameras compatible with this system are K-1 Mark II, K-1, K-3 II, KP, K-70, K-3, K-S2, K-S1 and K-50. For K-1, K-3 II, K-3, K-S2, K-S1 and K-50, the camera’s firmware must be upgraded to the latest version.
-WHAT'S IN THE BOX: Includes Front lens cap O-LC82, lens mount cap, Lens Hood PH-RBG82 and Lens case S130-160
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 comatic 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 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. HD is the abbreviation of High Definition. 3. Newly designed, large ring-type SDM In order to deliver the highest image quality possible over the entire focusing range — from the minimum focusing distance to infinity — this lens features an 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 unison. Generating a torque approximately 1.3 times that of the unit installed in the HD PENTAX-D FA50mm f1.4 SDM AW, this new SDM assures flawless, high-speed autofocus operation. 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 settings — 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.
