The Tokina atx-i 11-20mm F2.8 CF is designed as an ultra-wide-angle zoom lens for APS-C sensor DSLR cameras. It is the only f/2.8 ultra-wide-angle zoom lens for DSLR cameras with APS-C sensors currently available on the market. A focal length of 11-20 mm, covering the equivalent angles of 18mm, 21mm, 24mm, and 28mm wide-angle lenses, makes this lens attractive for those choosing between a standard zoom lens or an originally used wide-angle zoom kit lens. A constant maximum aperture of f/2.8 throughout the entire zoom range is achieved to deliver great results even in low light conditions, control depth of field, and allow for easy manual photography, all while maintaining a reasonable size and weight.
