DC lenses have an image circle that covers APS-C size image sensors. Not for use on digital cameras having image sensors larger than APS-C size or on 35mm or APS film cameras, as vignetting will occur. The angle of view varies depending on which camera the lens is mounted on. To find the 35mm camera-equivalent focal length, multiply the DC lens focal length by the crop factor (digital multiplier) of 1.5, 1.6, or 1.7, depending on the brand of DSLR camera on which the lens will be used. To find which DC lens is equivalent to a full-frame lens, divide the focal length of the full frame lens by the same crop factor.
AF will not function with Pentax ist* series and K100D DSLR cameras that do not support HSM.

 

FEATURES

Ultra wide-angle zoom lens with a large, constant aperture of F3.5, designed specifically for digital SLR cameras

This Ultra wide-angle zoom lens has a maximum aperture of F3.5 throughout the entire zoom range, making it suitable for low-light and indoor photography. It’s wide-angle of view from 102.4*degrees produces striking images with exaggerated perspective, enabling photographers to emphasize the subject. ELD (Extraordinary Low Dispersion) glass, SLD (Special Low Dispersion) glass and aspherical lenses provide excellent correction of all types of aberrations. The super multi-layer lens coating reduces flare and ghosting and creates high image quality throughout the entire zoom range. The HSM (Hyper Sonic Motor) ensures fast and quiet autofocus, while allowing full-time manual focus override.

* The angle of view changes depending on which camera model the lens is attached to.

 

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.

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.

 

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.

 

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.
