Sigma 10-20mm f/3.5 EX DC HSM ELD SLD Aspherical Super Wide Angle Lens for Nikon Digital SLR Cameras — Refurbished, 8% Off

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 emphasise, for example, expanses of a landscape.

Superior image quality: Two ELD (Extraordinary Low Dispersion) and one SLD(Special Low Dispersion)glass elements are employed for effective compensation of color aberratiuon. The use of two glass mould 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.

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.

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.
