Tokina AT-X 11-20mm f/2.8 Pro DX Lens (Nikon Fit)

The Tokina AT-X 11-20mm F2.8 PRO 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 sensors. The fast f/2.8 aperture lens offers an equivalent 16.5-30mm (35mm equiv.) zoom range.

The new optical design uses three aspherical lens elements (2 all-glass molded and 1 P-MO hybrid) to achieve superior contrast, sharpness, and correct for spherical aberrations. Additionally, Tokina uses three SD (super-low Dispersion, “FK01” and FK03”) glass elements to control chromatic aberrations.

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.
