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. The maximum aperture of f/3.5 allows enough light in to make it a great choice for indoor shooting as well as landscapes.
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.
Note! Vignetting will occur if the lens is used with 35mm SLR cameras or digital cameras with image sensors larger than APS-C size.
