zoom ultra-wide high opening for use with digital SLR cameras with PENTAX K bayonet, for high-resolution images.
Mounted on the digital SLR camera body of full-frame 35mm PENTAX K-1, this zoom lens covers focal dall'ultragrandangolare 15mm wide-angle to 30mm. * Thanks to the exaggerated perspective of a typical ultra wide lens, and to the very high resolving power, is able to capture dynamics visions of wide-ranging subjects, especially in landscape photography. Treated with the advanced HD Coating developed by PENTAX, it produces perfectly crisp images and fine detail, with excellent lighting even the edges of the image field, while chromatic aberration, distortion and coma are contained within a minimum level. The high F2.8 maximum aperture is useful for photographing night and starry skies environments. The engine built SDM (Supersonic Direct-drive Motor) provides quiet, high-speed AF.
* When mounted on a PENTAX digital SLR camera body of APS-C format, this zoom lens covers focal lengths equivalent to 23mm to 46mm.
Outstanding optical performance
Mounted on the digital SLR camera body of full-frame 35mm PENTAX K-1, this zoom lens covers wide-angle 30mm to 15mm focal dall'ultragrandangolare. The exaggerated perspective to the focal child helps the photographer to produce stunning images in landscape photography. Since it offers focal lengths from 30mm, it is also useful for impromptu photo applications such as snapshots.
optical design state of the art
This zoom lens incorporates three optical glass elements ED (Extra-low Dispersion) and three aspheric optical elements within an optical scheme consists of 18 elements in 13 groups, to provide high contrast images to the edges of the image field, minimizing the 'chromatic aberration, distortion and coma.
