Description
The Sigma 10-20mm f/3.5 EX DC HSM Autofocus Zoom Lens is a super-wide angle lens with a relatively bright f/3.5 maximum aperture throughout its zoom range, helping to ensure high image quality. The lens gathers enough light to make it a great choice for indoor shooting as well as landscapes and creative portraiture.With a wide angle viewing range of 102.4-63.8, this lens can empower a photographer to produce creative images with exaggerated perspective. Its Super Multi-Layer coating reduces flare and ghosting, and a HSM autofocus motor provides quiet operation, high speed, and perhaps most important the ability to manually override focus position at any time.The 10-20 f/3.5 EX DC HSM incorporates an inner focusing system to eliminate front lens rotation, which also makes the lens able to use an included petal-type bayonet hood to eliminate extraneous light from striking the front of the optic. Two ELD (Extraordinary Low Dispersion) glass elements and a SLD (Special Low Dispersion)
