The wide angle of view makes the Tokina 11-20mm a useful lens for landscape, architecture, and interiors, as well as for shooting in restricted spaces. Wide-angle lenses can also create some dramatic pictures, as they exaggerate the distance from the near to the far making subjects in the foreground appear very big. This is a popular technique in landscape photography, but can also be used to create striking images of other subjects in portrait or product photography. You need to get very close to the subject in the foreground to emphasis the effect, which has an impact on depth of field, so sharpness at the smaller apertures (such as f/11 to f/22) is important for photographers looking to capture maximum sharpness with a wide-angle lens.

The Tokina AT-X 11-20 F2.8 PRO DX ultra-wide angle lens features an expanded telephoto zoom range and improved optical performance. The lens is designed for use with Canon and Nikon DSLR cameras with APS-C (DX) sensors.
Tokina adds to its family of fast-aperture wide-angle zooms focused on providing photographers professional quality optics and construction at an affordable price. The fast f/2.8 aperture lens offers an equivalent 16.5-30mm* zoom range.
Aspherical and Super-low Dispersion glass elements
The 11-20mm has a new proprietary optical design that uses three aspherical lens elements (2 all-glass molded and 1 P-MO lens). Three SD (Super-low Dispersion: FK01 and FK03) glass elements achieves superior contrast and sharpness, and corrects for spherical aberrations.
This compact ultra wide-angle zoom lens has a bright, constant f/2.8 aperture making viewing and auto focus possible in low light situations but still maintaining portable size and weight.
One-Touch Focus Clutch
Tokina's exclusive One-touch Focus Clutch Mechanism allows the photographer to switch between AF and MF simply by snapping the focus ring forward for AF and back toward the lens mount for manual focusing. The lens is also designed to stand up to the rigors of daily use by photographers in a wide variety of shooting conditions and environments.
