Tokina atx-i 11-20mm F2.8 CF

About atx-i series

Leaving the honorable AT-X abbreviation, the letter "i" was newly added. "i" stands for "interactive", implying mutual communication between photographer and the lens. This is our believe that this series will provide a tight bond between photographer and the lens in order to capture in the image that the photographer sees around.

Exterior, specifications and performance of Tokina's popular and well acknowledged so far AT-X PRO lenses are reconsidered with the contemporary cameras in mind and launched under atx-i brand.

Product Overview

The Tokina atx-i 11-20mm F2.8 CF is designed as an ultra wide angle zoom lens for APS-C sensor DLSR cameras. It is the only f/2.8 fast ultra wide angle zoom lens for APS-C sized DSLR cameras on the current market*.

Focal length 11-20mm that covers equivalent angle of wide prime 18mm, 21mm, 24mm, 28mm lenses makes this lens attractive to be chosen after standard zoom lens or initially possessed wide angle zoom kit lens.

A constant maximum aperture of f/2.8 throughout the entire zoom range is realized to achieve great results in low light conditions, for depth of field control and easy manual shooting, while maintaining a reasonable size and weight.

Optical performance

To achieve an exceptional optical performance required for ultra wide angle zoom lens 3 aspherical glass elements and 3 Super-Low Dispersion glass elements were used in order to minimize distortion, manage spherical aberration and astigmatism while achieving excellent edge-to edge resolution and high contrast through the entire image.
