The Sigma 8-16mm F4.5-5.6 DC HSM is the first ultra-wide zoom lens with a minimum focal length of 8mm, designed specifically for APS-C size image sensors. This lens has an equivalent angle of view of a 12-24mm lens when used on digital cameras with an APS-C size image sensor.
The wide-angle of view from 121.2 degrees (the angle of view varies depending on which camera the lens is mounted on) produces striking images with exaggerated perspective, enabling photographers to emphasize the subject.
Four FLD glass elements, which have the performance equal to fluorite glass, compensate for color aberration. One hybrid aspherical lens and two glass mold elements give excellent correction for distortion and astigmatism.
Incorporating an inner focusing system, the lens produces high-definition images throughout the entire zoom range. The Super Multi-Layer Coating reduces flare and ghosting while superior peripheral brightness ensures high contrast images throughout the entire zoom range. This lens incorporates Hyper Sonic Motor (HSM), ensuring quiet and high speed auto focus, as well as full-time manual focus capability. It has a minimum focusing distance of 9.4 inches throughout the entire zoom range, which allows photographers to emphasize the subject by creating exaggerated perspectives.
This lens has a compact construction with an overall length of 4.2 inches and a maximum diameter of 2.9 inches.
