Tokina 11-20mm F/2.8 Pro Digital APS-C for Canon
Tokina SKU: ATXAF120DXC | Helix SKU: TKATXAF120DXC
Overview
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.

Tokina 16-28mm F/2.8 FX Lens for Canon
$ 629.00
Tokina 16-28mm F/2.8 FX Lens for Canon
Overview
This new Tokina lens is the first in a new generation of full frame (FX) lenses designed for professional digital SLR cameras like the Canon EOS 5D Mark II and the Nikon D700 and D3x. The 16-28 zoom range gives the professional photographer a super-wide angle of view to get close to subject for dramatic effect or to take in entire scenes.
NEW Silent DC Motor with GMR senor
The 16-28 F2.8 uses a newly developed silent DC motor that allows the lens to focus faster and more quietly then previous generations. The DC motor coupled with a new GMR magnetic AF sensor work together to increase AF Speed.
Aspherical and Super-low Dispersion glass elements
A new, 56mm in diameter, large sizes aspherical glass element is incorporated into the front lens group, while there are 2 more aspherical elements in the rear group. 3 SD super-low dispersion glass elements are also incorporated through-out the optical design to reduce chromatic aberration, give maximum resolution, more even brightness and distortion correction.
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 camera to focus
manually. There is no need to change the AF/MF switch on Nikon camera bodies* and there is no second AF/MF switch on the lens for Canon, everything is accomplished by the focus ring.
