Press Release: Pentax DA 18-270mm f/3.5-6.3 ED SDM Zoom Lens

11 September 2012

smc PENTAX-DA 18-270mm F3.5-6.3 ED SDM lens

PENTAX RICOH IMAGING UK LTD is pleased to announce the launch of the smc PENTAX-DA 18-270mm F3.5-6.3 ED SDM interchangeable zoom lens, designed for exclusive use with PENTAX K-mount interchangeable-lens digital cameras.

This high-magnification zoom lens offers 15x zoom ratio to cover focal lengths from 27.5mm wide angle to 414mm super telephoto in the 35mm format. Its built-in supersonic AF driving mechanism offers both a smooth and quiet AF mode in a compact, lightweight body.

Its extraordinary wide angle-to-long-telephoto zoom coverage makes this lens extremely versatile, as it allows the user to effortlessly capture a wide variety of subjects, without needing to change lenses, ranging from landscape and portraiture to long-range sports photography. Its newly designed optics are key to achieving such wide zoom coverage in a compact, lightweight body.

The PENTAX-DA 18-270mm will be available from early November. RRP £699.99.

Major Features

1. 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 an exceptionally smooth and quiet autofocus mode. When mounted on an SDM-compatible PENTAX K-mount interchangeable-lens digital camera body,* the focus mode is automatically switched to SDM-assisted autofocusing to ensure flawless AF operation.

2. Exceptional image definition

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.

3. 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 minimising the streaking effect of point light sources (coma)

Design and Specifications are subject to change without notice.

* 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.
