Overview

The Sigma AF 24–70mm f/2.8 DG OS HSM Art Lens is designed for different photography styles. This lens can be used with Canon cameras having an EF mount. Its optical design involves 19 elements arranged in 14 groups, including 3 SLD and 4 aspherical elements for reducing chromatic and spherical aberrations. Moreover, a super multi-layer coat is applied on the lens elements to minimize ghosting and lens flare as well as to improve contrast. The Hyper Sonic AF motor incorporated into the lens ensures fast and quiet autofocusing. Further, with the nine-blade diaphragm, the lens can generate a beautiful bokeh effect on images. The Optical Stabilizer compensates for camera shakes when shooting handheld. A composite material is used for the body of the lens, while brass is used for the bayonet mount.

Elements / Groups:	19 / 14
Elements / Groups: The individual pieces of glass that form the overall optical construction. Most lenses have between four and eleven elements to bend the light rays to ensure a perfectly formed image appears on the light sensitive surface, such as a film or CCD. The elements are arranged in groups and may be seen in specification sheets as, for example, 6 elements in 4 groups. That configuration may have two single elements and the other four grouped in pairs. View All Attribute Definitions
