OVERVIEW
- With a compact, lightweight design and weighing approximately 819 grams, this telephoto zoom lens covers the image circle of 35mm full-frame digital SLR’s and provides a focal length range of 70mm to 210mm which is ideal for handheld outdoor photography. It incorporates three ED (Extra-low Dispersion) glass elements and two anomalous dispersion glass elements to deliver high-contrast, high-resolution images with edge-to-edge sharpness, while effectively compensating for distortion and chromatic and coma aberrations. In addition to a short minimum focusing distance of 0.95 meters, the lens barrel was designed to be extension-free during AF operation in order to keep the overall dimensions intact. This allows the photographer to enjoy active field photography in a wide range of outdoor applications, including scenic photography, townscape shooting utilizing a beautiful bokeh (defocus) effect, close-up photography of animals and plants, and sports and wildlife photography where its outstanding portability really comes in handy.
- This lens features PENTAX’s latest HD Coating. Compared to conventional multi-layer coatings, this high-grade, multi-layer coating not only improves light transmittance but also reduces average reflectance in the visible light range by more than 50 percent. It effectively minimizes the adverse effects of flare and ghost images even in demanding lighting conditions such as backlighting.
- This zoom lens features a weather-resistant construction to prevent the intrusion of water into the lens barrel. When mounted on a PENTAX weather-resistant digital SLR camera body, it assures a durable, reliable digital imaging system that performs superbly in demanding shooting situations — even in rain or mist, or at locations prone to water splashes or spray.
