The Sigma 10-20mm f/3.5 EX DC HSM Autofocus Zoom is a super-wide angle lens with a maximum aperture of f/3.5 throughout the entire zoom range, ensuring high image quality. The maximum aperture of f/3.5 allows enough light in to make it a great choice for indoor shooting as well as landscapes and creative portraiture.
With its wide-angle view from 102.4 degrees, this lens can empower the photographer to produce creative images with exaggerated perspective. This lens has a Super Multi-Layer coating that coating reduces flare and ghosting. With a HSM (Hyper-Sonic Motor), the lens operates quietly and at high speed in both autofocus and full-time manual modes.
The lens design incorporates an inner focusing system which eliminates front lens rotation, making the lens particularly suitable for using the Petal-type hood, reducing extraneous light and reducing internal reflection.
Two ELD (Extraordinary Low Dispersion) glass elements and a SLD (Special Low Dispersion) glass element provide excellent correction of colour aberration. Four aspherical lenses provide correction for distortion and allow compact and lightweight construction. This Sigma lens has a minimum focusing distance of 24cm throughout the entire zoom range and a maximum magnification ratio of 1:6.6.
