Sigma announce 10-20mm F3.5 EX DC HSM




Sigma Corporation is pleased to announce the new SIGMA 10-20mm F3.5 EX DC HSM.

This super wide-angle lens has a maximum aperture of F3.5 throughout the entire zoon range. Its wide angle of view from 102.4 degrees produces striking images with exaggerated perspective. The maximum aperture of F3.5 is ideal for indoor shooting and it enables photographers to emphasise the subject.

Two ELD (Extraordinary Low Dispersion) glass elements and one SLD (Special Low Dispersion) glass element provide excellent correction of colour aberrations. Four aspherical lenses provide correction for distortion and allow its compact and lightweight construction. The Super Multi-Layer coating reduces flare and ghosting ensuring high image quality throughout the entire zoom range.

The incorporation of HSM (Hyper Sonic Motor) enables quiet and high-speed auto focus as well as full-time manual focusing capability. This lens has a minimum focusing distance of 24cm (9.4 inches) throughout the entire zoom range and a maximum magnification ratio of 1:6.6.

The lens design incorporates an inner focusing system which eliminates front lens rotation, making the lens particularly suitable for using the Petal-type hood. The, included, Petal-type hood blocks extraneous light and reduce internal reflection.
