AT-X PRO
AT-X 11-20 F2.8 PRO DX
 
 
 
The Tokina AT-X 11-20 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 f/2.8 aperture lens offers an equivalent 16.5-30mm* zoom range.
Aspherical and Super-low Dispersion glass elements
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 f/2.8 aperture making viewing and auto focus possible in low light situations but still maintaining portable size and weight.
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 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.
AT-X 116 PRO DX II
   Tokina AT-X 116 f/2.8 PRO DX II (11-16mm) is an update to the widely popular and award winning Tokina AT-X 116 f/2.8 PRO DX (11-16mm) lens.
The main update to this lens is in the Nikon mount, the AT-X 116 PRO DX II has an internal silent focusing motor to allow the lens to AF on Nikon bodies that do not have an AF drive gear and motor.
There have also been some adjustments made to the coating for slightly improved optical performance.
This compact ultra wide-angle zoom has a bright constant f/2.8 aperture make viewing and auto focus possible in lower light situations but still maintaining a reasonable size and weight.
Two Super-Low Dispersion glass elements and two aspheric glass allow the proprietary optical design to achieve excellent contrast and sharpness as well as controlling chromatic aberration.

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.
Other than the optical coating change there are no changes to the Canon mount. The AT-X 116 PRO DX II for Canon uses the same AF motor and AF drive system as the the previous model.
AT-X 12-28 PRO DX
   The Tokina AT-X 12-28 PRO DX lens has a super-wide to standard zoom range while maintaining a constant fast f/4 aperture. This makes ita very versatile lens for different photo applications such as scenery, street scenes photography and event coverage. The lens is designed for DSLR cameras with APS-C (DX) sized sensors.
Aspherical and Super-low Dispersion glass elements
A new optical design using aspherical elements and super-low dispersion glass matches even the highest mega-pixel DX sensors cameras available today.
One asphericallenselement is positioned in the front group. This together with another precision molded glass aspherical lens element placed in the rear group ideally focuses marginal light rays andmaintains sharpness at the edgeswhile also correcting distortion. The use of two different SD (Super-low Dispersion) glass elements, type FK01 and FK03, corrects chromatic aberration. The combination of all these specialized elements in the optical design yield excellent sharpness and color.
New auto focus mechanism
The new AF “GMR magnetic precision” control sensor is capable offastauto-focus. Tokina placed the new sensor closerto the drive unit in the lens for faster communicationbetween the controller and AF motor. This combined with the motor’s high-precision focus control yields faster, more accurate auto-focus.
Additionally, a brand new “SD-M” (Silent Drive-Module) has greatly lowered the sounds emitted by the auto focusdrive system allowing for much quieter AF. Both Canon and Nikon mounts have a built-in AF motor to make them auto-focus compatible with all current camera bodies.
Compact body design
The Tokina AT-X 12-28 PRO DX compact design makes the lens easy to carry and handle. Manual focus is achieved through Tokina’s one-touch focus clutch AF/MF mechanism. Simply slide the manual focus ring forward for auto-focus or back for manual focus operation. The lens focus ringis damped in the manual mode for smooth and precise focusing.
In addition the lens has a 77mm filter size allowing filters such as the low-profile circular polarizer or UV to be used.
AT-X 14-20 F2 PRO DX
   The Tokina AT-X 14-20 F2 PRO DX is a wide-angle zoom lens with super-fast f/2 aperture. The lens is designed for use with either Canon or Nikon DSLR cameras with APS-C sensors.
Tokina adds its fastest lens to date to its family of fast-aperture wide-angle zooms focused on providing photographers professional quality optics and construction at an affordable price. The extremely fast f/2 aperture lens offers an equivalent 21-30mm zoom range. The super-bright, constant f/2.0 aperture makes viewing, auto focus and shooting possible in very low light situations while still maintaining reasonable size and weight.
Aspherical and Super-low Dispersion glass elements
The 14-20mm has an all-new proprietary optical design that uses three aspherical lens elements (2 all-glass molded and 1 P-MO lens). This combination achieves superior contrast and sharpness, and corrects for spherical aberrations. Additionally, Tokina uses four SD glass elements (Super-low Dispersion: FK01 and FK03) to control chromatic aberrations, distortion and astigmatism. Two of the elements are SD glass molded aspherical lenses.
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 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.
