Exceptional imaging power
Consisting of 17 elements in 12 groups, this new lens features three ED (Extra-low Dispersion) optical elements, one anomalous-dispersion-glass aspherical optical element and three aspherical optical elements to complement superhigh-resolution image sensors.

By delivering sufficient light even at the edges and minimising aberrations, this zoom lens provides a high MTF (Modulation Transfer Function) for finely-detailed high contrast, high-resolution images.

When mounted on a current PENTAX K-series camera body, it uses only the central area of the image circle to deliver high-resolution images with uniform detail.

Large-aperture standard zoom lens
When mounted on a 35mm-format full-frame DSLR, this lens offers a zoom ratio of approximately 2.9 times from ultra-wide-angles to standard zoom ranges (24mm to 70mm in focal length). It provides a maximum aperture of F2.8 over the entire zoom range to deliver brilliant images. It not only covers the most common focal-length range but also provides ultra-wide-angle coverage to produce distinctive visual results, such as exaggerated perspectives or extra-wide depths of field; this makes it very useful with subjects such as sweeping landscapes and shallow indoor scenes.

When mounted on a current K-series DSLR, it provides focal lengths from 37mm to 107mm in the 35mm format to cover wide-angle to medium-telephoto ranges. Its large maximum aperture not only creates an excellent bokeh effect on the background for beautiful portraits but also allows the photographer to handhold the camera for poorly lit subjects, such as sunsets or indoor scenes

Built-in SDM (Supersonic Direct-drive Motor)
Thanks to the incorporation of a new-generation SDM (Supersonic Direct-drive Motor), this zoom lens ensures quiet, high-speed autofocus operation, allowing the photographer to react swiftly to all types of photographic opportunities.

Weather-resistant construction
This lens features a dependable weather-resistant construction with special seals to effectively prevent water from reaching the inside of the lens. Pairing it with a weather-resistant PENTAX DSLR provides a durable, dependable digital imaging system that performs superbly in demanding shooting conditions or locations, where the weather or indeed water, would normally cause problems.
