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 color aberration. Four aspherical lenses provide correction for distortion and allow compact and lightweight construction. This Sigma lens has a minimum focusing distance of 9.4 inches (24cm) throughout the entire zoom range and a maximum magnification ratio of 1:6.6. Note! Vignetting will occur if the lens is used with 35mm SLR cameras or digital cameras with image sensors larger than APS-C size Super-Wide 10-20mm lens with a maximum aperture of f/3.5 throughout the entire zoom range High Image Quality Two ELD (Extraordinary Low Dispersion) glass elements and a SLD (Special Low Dispersion) glass elements and four aspherical lenses
