The Sigma 10-20mm
f/4-5.6 is a super wide-angle zoom lens designed exclusively for digital SLR cameras with APS-C sensors.
This ultra-wide zoom lens has a wide angle of view from 102.4 - 63.8 degrees (when Sigma mount is used) and it is exclusive to digital SLR cameras. SLD glass elements effectively compensate colour aberration. Aspherical lenses provide maximum correction for distortion and various aberrations; high image quality is displayed throughout the entire zoom range. The HSM equipped models makes fast AF speeds and quiet shooting a reality, and it is also capable of full-time manual focus. It has a minimum focusing distance of 24cm (9.4") at all focal lengths. It is also equipped with an integral Petal-type hood to block out extraneous light.
Ultra-wide zoom lens
The Sigma 10-20mm F4-5.6 EX DC HSM lens gives you super wide-angle photography and is ideal for indoor shooting and landscape photography. Wide angle of view 102.4-63.8 degrees (for Sigma mount). The angle of view changes depending on which camera model the lens is attached to.
The multi layer lens coating and lens design reduce flare and ghost and also creates an optimum colour balance through the entire zoom range.
Correction of aberrations
Three SLD (Special Low Dispersion) glass elements are employed for effective compensation of colour aberration, which is a common problem with super-wide angle lenses. One piece of glass mold and two hybrid aspherical lenses, offer excellent correction for distortion, as well as all types of aberration.
Inner focus system
This lens incorporates an internal focusing system, which eliminates front lens rotation allowing the use of a Petal-type Hood.
HSM (Hyper Sonic Motor)
The HSM equipped models ensure a silent, high-speed AF function as well as full-time manual focusing capability for Sigma, Canon, and Nikon-D mount lenses. Minimum focusing distance of 24cm at all focal lengths This lens has a minimum focusing distance of 24cm throughout the entire zoom range.
