AT-X 11-20 PRO DX
EXPANDED TELEPHOTO ZOOM RANGE
IMPROVED OPTICAL PERFORMANCE
The Tokina AT-X 11-20mm 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  F2.8  aperture  lens  offers  an  equivalent 
16.5-30mm* zoom range. 
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 F2.8
aperture making viewing and auto focus possible in low light situations
but still maintaining portable size and weight. 
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.
 The lens is designed for Digital cameras with APS-C sized CMOS and CCD sensors, 
   not designed for cameras with Full Frame sensors. .
