Specifications for Pentax HD-D FA 70-200mm F2.8 ED DC AW Telephoto Zoom Lens: Manufacturer: Pentax Color: Black Features of Pentax HD-D FA 70-200mm F2.8 ED DC AW Telephoto Zoom Lens This telephoto zoom lens has been developed as a new model of the high-performance Star () series which assures exceptional image rendition with edge-to-edge sharpness by effectively compensating various aberrations to a minimum. When mounted on a PETAX K-mount SLR camera body it provides a zoom ratio of approximately 2.9 times to cover a telephoto range from 107mm to 307mm in the 35mm format. Since it provides a large maximum aperture of F2.8 over the entire zoom range it is ideal for portraiture with beautifully defocused foreground/ background and sports photography demanding high shutter speeds to freeze the action. Its image circle is optimized to cover even the image size of 35mm film format SLR cameras. As the result it not only assures brilliant high-resolution images without compromising the sharpness at edges even when mounted on an existing PENTAX digital SLR camera body but it is also capable of accepting future models with larger image sensors without modifications. This zoom lens is treated with the newly developed Aero Bright Coating II - a lens-coating nanotechnology that employs a super-low refractive film fabrication process to assure light reflectance lower than that of the conventional Aero Bright Coating. By coupling this advanced lens coating with the high-grade multi-layer HD Coating that reduces an average reflectance in a visible ray spectrum to less than 50percent of conventional multi-layer coatings this lens effectively reduces flare and ghost images to a minimum even under demanding lighting conditions such as backlight. In its optics it also features four super-low dispersion glass elements two ED (Extra-low Dispersion) glass elements and two Super ED glass elements which have optical properties similar to fluorite and assure lower light dispersion and more effective compensation of chromatic aberration. As the result this lens produces brilliant high-contrast images with edge-to-edge sharpness while effectively compensating chromatic aberration over the entire zoom range. Developed as an AW (All Weather) model this zoom lens features a dependable dustproof weather-resistant construction with 13 special seals to prevent the intrusion of water and dust particles into the lens interior. By pairing it with a PENTAX weather-resistant 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 lens is equipped with the PENTAX-developed Quick-Shift Focus System which allows the user to instantly switch to manual-focus operation after the subject is captured in focus by the cameras AF system. In order to improve its operability a three-position switch is newly installed on this lens allowing instant switching among QFS/A QFS/M and MF modes. QFS/A is an autofocus-priority mode which allows the user to switch to manual-focusing operation only when autofocus operation is completed. QFS/M is a manual-focus-priority mode which enables the user to switch to manual focusing at any time - even when the AF system is in operation. MF mode allows the user to instantly switch to manual focusing with a simple twist of the focus ring on the lens. With a choice of three distinctive modes the user is assured of speedier more accurate focusing operation for a given subject or application.
