This compact and lightweight telephoto zoom lens is perfect for every journey. Weighing approximately 819 grams, the design covers the 35mm image circle of full-frame DSLRs and provides a focal length range of 70mm to 210mm, ideal for handheld outdoor photography. When mounted on an APS-C camera, the focal length range extends to the equivalent of 107mm to 322mm in the 35mm format.

The optics consist of 20 elements in 14 groups, incorporating three ED (Extra-low Dispersion) glass elements and two anomalous dispersion glass elements. This lens delivers high-contrast, high-resolution images with edge-to-edge sharpness, effectively compensating for distortion and chromatic and coma aberrations. The lens barrel was designed not to extend during operation, allowing the photographer to actively enjoy outdoor photography in a wide range of shooting situations, including landscape, townscape, close-up of animals and plants, as well as sports and wildlife photography.

The lens features the latest HD Coating from PENTAX, which improves light transmission and reduces average reflectance in the visible light range by more than 50 percent, minimizing the adverse effects of flare and ghosting even in challenging lighting conditions.

Incorporating a weather-resistant construction, this zoom lens prevents 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.

The front surface of the lens features SP (Super Protect) Coating, 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, freeing the photographer from worries in outdoor photography.

This lens incorporates a ring-type SDM (Supersonic Direct-drive Motor) to ensure quiet, high-speed AF operation and improve operability in outdoor shooting. Additional features include the Quick-shift Focus System, a two-step focus range limiter to minimize AF operation time, a nine-blade, round-shaped diaphragm to produce a natural, beautiful bokeh effect, and electromagnetic diaphragm control for high-precision exposure control during video shooting.

The PENTAX digital SLR K series cameras are equipped with the SR (Shake Reduction) mechanism built into the camera body, providing image stabilization for any lens compatible with the K-Series cameras.

Thanks to the use of high-quality optics, including three ED glass lens elements and two super-low dispersion glass lens elements, this lens achieves clear images with less chromatic aberration. The 20 lens elements ensure sharp images are captured even at the edges, regardless of the focal length.

The HD Coating enhances the imaging power of the camera, producing high-contrast images with edge-to-edge sharpness, free of flare and ghost images. The PENTAX-original Super Protect (SP) Coating on the front surface prevents the adhesion of dust, water drops, grease, and other substances, making it easier to clean.

With a minimum focusing distance of 0.95 meters, this lens allows for high-quality close-up photography in a variety of situations. The weather-resistant construction ensures reliable performance even when shooting outdoors.
