Capture images beyond what your eyes can see with Sigma 10-20mm F3.5 EX DC HSM. This ultra wide-angle zoom lense has constant aperture from F/22 to F/3.5 and 82mm diameter filter for photography in minimal lighting. The main feature of this lens is its ultra-wide angle zoom view from 102.4° that enables the photographer to produce outstanding images with exaggerated perspective and subject emphasis. This feature, combined with HSM drive autofocus that can be overridden by full-time manual focus, you can achieve images of highest angle, range, and clarity. Aberrations are minimized, thanks to its ELD, SLD, and aspherical glass elements while the super-multi-layer optical coating eliminates glare, flare, and ghosting across the zoom range. Unneeded outside light effects are blocked by a petal-type hood, aptly suited for the lens' inner focusing system that prevents front lens rotation. Larger-than-life photography is at your fingertips once you use this Sigma 10-20mm F3.5 EX DC HSM. It is compatible only with APS-C DSLR Cameras.
Product Features in Detail
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.
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.*
*AF will not function with Pentax ist* series and K100D DSLR cameras that do not support HSM.
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.
*Vignetting will occur if the lens is used with digital cameras with image sensors larger than APS-C size or 35mm SLR cameras.
