Manufacturer's Description:

"A Large-aperture-wide-zoom lens from 20mm with large F2.8 aperture

SIGMA has created a new 20-40mm lens with F2.8 hroughout its zoom range, from ultra-wide 94.5 degrees to near-standard 56.8 degrees angle of view, for photographers to shoot more creatively from various angles and zoom perspectives. With a fast F2.8 maximum aperture superior peripheral brightness is ensured. This lens is perfectly suited for indoor shootings even in dim light without worrying about blurring in photos. These features also make this lens desirable for use with Digital SLR Cameras."
