• Ultra-wide 11-16mm focal length
• Constant maximum aperture of f/2.8
• Excellent optical performance
• Internal focus
• Water-repellent coating
• One-touch Focus Clutch mechanism
• Greatly balanced cost performance

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 an internal survey September 2019).

The functional 11-16mm focal length is chosen to position this lens as an easy demanded gear after standard zoom lenses or an 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 excellent results in low light environments for depth of field control and easy manual shooting while maintaining the lens's reasonable size and weight.

Optical Performance

To achieve an exceptional optical performance demanded ultra-wide-angle zoom lens is still and video shooting purposes, two aspherical glass elements and two Super-Low Dispersion glass elements were used to minimize distortion, manage spherical aberration and astigmatism while achieving excellent edge-to-edge resolution and contrast of the entire image. Great efforts were made to control light fall-off at all focal lengths.

Built Quality & Exterior Design

True to traditions, Tokina incorporated many metal parts inside the lens for a reassuring built quality and long time utilization in different shooting conditions.

The sophisticated exterior design is specifically developed to match the design of modern DSLR cameras.

Mechanics & Electronics

Precise attention was also paid to zoom and focus ring rotation, which is convenient with no play and made just tightly enough damped.

The Tokina atx-i 11-16mm F2.8 CF for Nikon F mount incorporates internal silent focusing motor in combination with a precise GMR sensor to allow the lens to AF on Nikon bodies that do not have an AF drive gear and motor.

Highly valued One-touch focus Clutch mechanism allows switching between autofocus and manual focus easy.

The overall length of the Tokina atx-i 11-16mm F2.8 CF does not change when focusing and zooming, thanks to the internal type of the focus construction.
