Tokina AT-X 16-28mm F2.8 FX Lens

Take in the entire scene and capture brilliant images with the Tokina AT-X 16-28 F2.8 PRO FX. With its f/2.8 - f/22 aperture range, no matter what the lighting condition, you're sure to capture breathtaking photos with it. It has a super-wide angle view with 16-28 mm focal length to give your photos a dramatic effect. It's made with multi-layer coating to reduce or eliminate reflections even in the brightest environment. The Internal Focus System has a more compact design, allowing you to focus faster and use filters, and improving handling due to fewer movements near the center of gravity. It is constructed with 15 Lens Elements in 13 Groups for better lens performance, a One Touch Focus Clutch which allows you to easily switch from AF to MF, and a silent DC Motor with GMR Sensor for easier, quieter and faster focusing. It is compatible with APS-C and Full Frame Sensor DSLR Cameras.

Product Features in Detail

Take in the Entire View
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 sensor
The 16-28 f/2.8 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. 

Ashperical Optics
A new, 56mm in diameter, large sized aspherical glass element is incorporated into the front lens group, while there are 2 more aspherical elements in the rear group.

Super Low Dispersion Glass
3 SD super-low dispersion glass elements are also incorporated throughout 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.

Internal Focus System
The two main methods of lens focusing are either the complete straight forward movement of elements (used mainly with single focal length lenses), or the rotation of the entire front lens barrel group (used mainly with zoom lenses). The internal focusing system used by Tokina moves each lens group, but does not change the overall length of the lens - this is especially useful with telephoto designs.
