Quiet and fast AF

This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed auto focus as well as full-time manual focus override by rotation of the focus ring.*

* AF will not function if the Pentax camera bodies do not support HSM.

Exaggerated perspective

This ultra wide-angle lens allows photographers to create an exaggerated perspective between the subject and the background to emphasize, for example, expanses of a landscape.

Large F3.5 aperture through the entire zoom range

The large, constant aperture of F3.5 provides a bright image in the viewfinder, which helps photographers easily check focusing and composition.

Petal-type Hood

An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using the included petal-type lens hood which blocks out extraneous light.

Superior image quality

Two ELD (Extraordinary Low Dispersion) and one SLD(Special Low Dispersion)glass elements are employed for effective compensation of color aberration. The use of two glass mold and two hybrid aspherical lenses offer excellent correction for distortion and astigmatism and assure superior image quality. The super multi-layer coating reduces flare and ghosting and provides high contrast images throughout the entire zoom range.

Minimum focusing distance of 24cm (9.4")at all focal lengths

This lens has a minimum focusing distance of 24cm (9.4 inches) throughout the entire zoom range. This close focusing distance on such a wide-angle lens emphasizes perspective and allows the photographer to capture high quality images, not only of the foreground subject but also the surrounding scenery.
