Tokina AF ATX-I 11-16mm f2.8 CF PLUS Canon EF

About atx-i Series

Leaving the honorable AT-X abbreviation, the letter "i" was newly added. The "i" stands for "interactive", implying mutual communication between photographer and the lens. Our belief is that this series will equip photographers with the ability to substantially engage with capture capture the atmosphere around them.

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 11-16mm F2.8 CF (CF means cropped frame) 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 in the current market (according to internal survey September, 2019).

The useful 11-16mm focal length is chosen in order to position this lens as an easy demanded gear after standard zoom lenses or initial wide angle zoom lens to start with.

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

Optical Performance

To achieve an exceptional optical performance demanded for ultra wide angle zoom lens in still and video shooting purposes, two aspherical glass elements and two 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 contrast of the entire image. Great efforts were done to control light fall-off at all focal lengths.
