The Tokina AT-X 14-20 F2 PRO DX is a wide-angle zoom lens with super-fast f/2 aperture. The lens is designed for use with either Canon or Nikon DSLR cameras with APS-C sensors.

Tokina adds its fastest lens to date to its family of fast-aperture wide-angle zooms focused on providing photographers professional quality optics and construction at an affordable price. The extremely fast f/2 aperture lens offers an equivalent 21-30mm zoom range. The super-bright, constant f/2.0 aperture makes viewing, auto focus and shooting possible in very low light situations while still maintaining reasonable size and weight.

Aspherical and Super-Low Dispersion Glass Elements

The 14-20mm has an all-new proprietary optical design that uses three aspherical lens elements (2 all-glass molded and 1 P-MO lens). This combination achieves superior contrast and sharpness, and corrects for spherical aberrations. Additionally, Tokina uses four SD glass elements (Super-low Dispersion: FK01 and FK03) to control chromatic aberrations, distortion and astigmatism. Two of the elements are SD glass molded aspherical lenses.

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.
