This high-magnification zoom lens offers 15-times zoom ratio to cover focal lengths from wide angle to super telephoto, while its built-in supersonic AF driving mechanism achieves both smooth, quiet AF operation and a compact, lightweight body. Its extraordinary wide angle-to-long-telephoto zoom coverage makes this zoom lens extremely versatile and handy, as it allows the user to effortlessly capture a wide variety of subjects, ranging from landscapes and snapshots to sports events, without the need to change lens.
15-times zoom covering the extra wide range. - When mounted on a PENTAX K-mount lens-interchangeable digital camera body, this zoom lens offers an 15-times zoom ratio covering focal lengths from 27.5mm wide angle to 414mm super telephoto in the 35mm format. This allows the photographer to capture a wide range of scenes and subjects without changing lenses - ranging from such casual applications as scenery, snapshot and portraiture to long-range sports photography. Its newly designed optics is the key to achieving such wide zoom coverage in a compact, lightweight body, for optimal versatility and manoeuvrability.
Supersonic AF motor (SDM) - Thanks to the incorporation of the PENTAX-original SDM autofocus system driven by a built-in supersonic motor, this zoom lens offers exceptionally smooth and quiet autofocus operation. When mounted on an SDM-compatible PENTAX K-mount lens-interchangeable digital camera body, the focus mode is automatically switched to SDM-assisted autofocusing to ensure dependable, flawless AF operation. ----This lens is compatible with the K-5 II, K-5 II s, K-30, K-01, K-5, K-r, K-7, K-x, K-m, K20D, K200D, K100D Super and K10D camera bodies (with Ver. 1.30 or later firmware installed). When mounted on other camera bodies, the focus mode is automatically switched to manual.
Exceptional image detail - Incorporating two extra-low dispersion (ED) elements in its optics, this zoom lens delivers bright, high-resolution images even at the edges, while effectively minimizing chromatic aberration.
Other features - Minimum focusing distance of 0.49m over the entire zoom range. Rounded diaphragm to produce a smooth, beautiful bokeh (out-of-focus rendition), while minimizing the streaking effect of point light sources.
