The new Sigma 8-16mm f4-5.6 DC HSM is an ultra wide-angle zoom lens designed specifically for DSLRs with APS-C size sensors on which it shows an equivalent focal length of a 12-24mm.

The lens delivers the 121.2-degreeangle of view, which produces striking images with exaggerated perspective, giving the photographers much room for creativity. It has a minimum focusing distance of 24cm throughout the entire zoom range.

In its construction the 8-16mm f/4-f5.6 combines 15 elements in 11 groups. There are four FLD (“F” Low Dispersion) glass elements among its optics which perform like fluorite glass compensating for color aberration, one hybrid aspherical lens and two glass mold elements which successfully correct distortion and astigmatism typical of wide-angle lenses.

The elements also feature Super Multi-Layer Coating to reduce flare and ghosting. All this ensures high contrast and high definition images at any focal length.

This lens incorporates HSM (Hyper Sonic Motor) that makes quiet and high speed AF possible while providing for full-time manual focus capability. There’s an inner focusing system in the lens, which allows for convenient usage of filters.

It’s rather a compact lens and comes supplied with petal-type hood to block out extraneous light. The lens weighs ~half a kilo, and its overall length makes 105.7mm while its maximum diameter is 75mm
