Major Features
  1. 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 lens changes — 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 maneuverability.
  2. 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.

  3. Exceptional image description

    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.
  4. Other features

    1. Minimum focusing distance of 0.49m over the entire zoom range
    2. Rounded diaphragm to produce a smooth, beautiful bokeh (out-of-focus rendition), while minimizing the streaking effect of point light sources
