Sigma 10-20mm f/3.5 EX DC HSM Lens

With an F3.5 aperture throughout the entire zoom range, the 10-20mm F3.5 is perfect for low light photography. Sigma wide angle lenses accentuate the relationship of subjects within a photo and thus become an important creative tool. This Sigma fast fixed aperture makes photography easier for the photographer who wishes to precisely control their depth of field and also for working with non TTL Flash systems.

Super Multi-layer coating reduces flare and ghosting, four aspherical lenses provide correction for distortion and inner focusing system eliminates front lens rotation and suitable for use of polarizing filters. Perfect for shooting landscape photography, architecture, building interiors, photojournalism, wedding photography, group pictures and more.

Ultra wide-angle zoom from 102.4* degrees

The 10-20mm F3.5 EX DC HSM lens offers photographers greater freedom of expression by rotating the zoom ring. It is a very powerful tool for architectural, indoor and landscape photography. 
※ The angle of view changes depending on which camera model the lens is attached to.

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.
Petal-type Hood

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.

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.

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.

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.
