Tokina - Digital Eyes.
A versatile wide-angle zoom for Nikon DX-format DSLRs, the AT-X 11-20mm f/2.8 PRO DX Lens from 
Tokina offers a 16.5-30mm equivalent focal length and features a constant f/2.8 maximum 
aperture for maintained brightness throughout the zoom range. One P-MO hybrid aspherical 
element and two glass-molded aspherical element work in tandem to minimize distortions and 
control various aberrations while three SD ultra-low dispersion elements reduce chromatic 
aberrations for increased clarity. A multi-layer lens coating has also been applied to further 
enhance overall light transmission and color accuracy by suppressing lens flare and ghosting. 
Well-suited to working in a wide variety of situations, this ultra-wide zoom covers an array of 
wide-angle perspectives while maintaining consistent illumination for working in challenging 
lighting.
