HD PENTAX-D FA 15-30mm F2.8 ED SDM WRA large-aperture, ultra-wide-angle zoom lens for use with PENTAX K-mount digital SLR cameras, providing sharp, high-resolution images
When mounted on the PENTAX K-1 35mm full-frame digital SLR camera body, this zoom lens covers a focal-length range from 15mm ultra-wide-angle to 30mm wide-angle.* Thanks to its exaggerated perspective typical of an ultra-wide-angle lens and high-resolution imaging power, it captures dynamic, sweeping views of subjects, especially in landscape photography.
Treated with the PENTAX-developed HD Coating, it produces well-defined, fine-detailed images with ample light levels even at the edges of the image field, while effectively reducing chromatic aberration, distortion and coma to a minimum. Its large F2.8 maximum aperture also comes in handy for photographing nightscapes and starry skies. The built-in SDM (Supersonic Direct-drive Motor) provides quiet, high-speed autofocus operation.
* When mounted on a PENTAX APS-C-size digital SLR camera body, this zoom lens covers a focal-length range from 23mm to 46mm.
