A compact, lightweighted and weather-resistant telephoto zoom lens for use with 35mm-format full-frame digital SLR providing great poratability

Even though it has a highly portable design, this high-performance zoom lens covers a 35mm full-frame image circle. Its compact, lightweight, weather-resistant body lets users carry it anywhere with ease, and effortlessly capture high-quality images of a wide range of subjects, including landscapes, portraits, close-ups and sports events. Use of the high-grade, multi-layer HD Coating to the optics optimizes the overall lens coating performance, while assuring edge-to-edge sharpness and minimizing flare and ghost images in backlit situations. Thanks to a minimum focusing distance of 0.95 meters and a maximum magnification of 0.32 times, it provides a photographic coverage much wider than that of previous models.

Compact, lightweight telephoto zoom lens with outstanding portability

Despite its compact, lightweight design weighing approximately 819 grams, this zoom lens covers the image circle of 35mm full-frame digital SLRs, and provides a focal length range of 70mm to 210mm to facilitate handheld outdoor photography. When mounted on an APS-C-format camera, its focal length range is extended to the equivalent of 107mm to 322mm in the 35mm format. Coupled with its compact, lightweight body, it can be easily integrated in any APS-C-format camera system. In its 20-element, 14-group optics, 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. The lens which allows the photographer to enjoy active field photography in a wide range of outdoor applications, including scenic photography, townscape shooting and wildlife photography where its outstanding portability really comes in handy.

Minimum focusing distance of 0.95 meter

This lens can be used as a tele-macro lens as the minimum focusing distance of 0.95 meter has been achieved for both the tele and wide, with the maximum magnification, 0.32x. By using with APS-C the maximum magnification is 0.48x

HD Coating to enhance imaging power　

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, minimizing the adverse effects of flare and ghost images even in demanding lighting conditions such as backlighting.
* HD is an abbreviation of High Definition.

Weather-resistant construction, perfect for outdoor photography

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 settings — even in rain or mist, or at locations prone to water splashes or spray.

Built-in SDM

This lens incorporates a ring-type SDM (Supersonic Direct-drive Motor) to assure quiet, high-speed AF operation and improve operability in outdoor shooting.

Focus limiter

Two-step focus range limiter, to minimize AF operation time

Electromagnetic diaphragm control,* to provide high-precision exposure control during video shooting

USAGE NOTE:About KAF4 lens mount

SP Coating to repel stains

This lens features SP (Super Protect) Coating on its front surface. Applied by means of a PENTAX-exclusive fluorine deposition process, this coating is highly repellent to water, grease and dirt, making it easy to wipe off stains such as fingerprints. This frees the photographer from worries in outdoor photography.

Other features

1.Quick-shift Focus System, to provide instant shift to manual-focus operation, after locking the subject in focus during AF operation by pressing the shutter-release button halfway down
2.Nine-blade, round-shaped diaphragm, to produce a natural, beautiful bokeh (defocus) effect, while minimizing the streaking effect of point light sources
