| Additional information:
The Tokina AT-X 11-20mm F2.8 PRO DX is an ultra-wide angle designed for use with Canon and Nikon DSLR cameras with APS-C (DX) sensors.
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.
