The Tokina atx-i 11-16mm F2.8 CF (CF stands for Cropped Frame) is designed as an ultra-wide-angle zoom lens for DSLR cameras with an APS-C sensor. It is the only fast ultra-wide-angle zoom lens with f/2.8 for APS-C DSLR cameras on the current market (according to an internal survey in September 2019).
The practical focal length of 11-16 mm was chosen to position this lens as an easily sought-after tool after a standard zoom lens or as the first wide-angle zoom lens for beginners.
A constant maximum aperture of f/2.8 throughout the zoom range is realized to provide excellent low-light results, selective depth-of-field control and easy manual shooting, while maintaining a reasonable size and balanced weight of the Lens.
Optical performance
To achieve the exceptional optical performance required for an ultra wide-angle zoom lens in the photo and video fields, two aspherical glass elements and two super low-dispersion glass elements have been used to minimize distortion and control spherical aberration and astigmatism, while achieving excellent edge-to-edge sharpness and high contrast across the entire image.
Great efforts have been made to control light fall-off at all focal lengths. The anti-reflective multi-layer coating improves light transmission and minimizes reflections, while the water-repellent coating makes it easy to wipe and clean the surface of the front glass element.
Build quality + exterior design
True to its traditions, Tokina has integrated numerous metal parts inside the lens to ensure reliable build quality and long-term use in a variety of shooting conditions.
The sophisticated exterior design has been specially developed to match the design of modern DSLR cameras.
Mechanics + electronics
The rotational resistance of the zoom and focus rings has also been tuned with great care - with smooth operation without play and exactly the right amount of damping.
The Tokina atx-i 11-16mm F2.8 CF for Nikon F bayonet has an internal quiet focusing motor in combination with a precise GMR sensor, so that the Lens can also focus automatically on Nikon camera bodies without its own AF drive and motor.
The highly appreciated one-touch focus clutch mechanism allows easy switching between autofocus and manual focus.
The overall length of the Tokina atx-i 11-16mm F2.8 CF does not change when focusing and zooming thanks to the internal focus construction.

For photography
The ultra-wide-angle focal length of 11-16 mm in combination with the constant maximum aperture of f/2.8 makes this Lens an indispensable tool for the following photography genres: landscape, group photos and environmental portraits, architecture (especially interiors), automotive photography, street photography and night photography.
For video production
The Tokina atx-i 11-16mm F2.8 CF has been specifically designed with videographers and filmmakers who shoot both stills and video professionally in mind and offers the following benefits for these users:
Wide cinematic angle of view that provides security even in small spaces.
Minimized focus breathing - the image section does not change when the focus is adjusted.
Natural footage - the image is not distorted when panning due to the almost non-existent distortion.
Constant aperture for using the zoom during filming.
Note:
The Tokina atx-i 11-16mm F2.8 CF is designed for compatibility with DSLR cameras (APS-C size). When used on cinema cameras such as Blackmagic, it is recommended to use the Lens in manual focus mode.
The Tokina atx-i 11-16mm F2.8 CF is perfectly suited for use with a gimbal:
Ideal wide-angle solution according to cinematic standards.
Lightweight.
Zoom capability that allows the user to use different angles of view with the same Lens.
Since the total length does not change thanks to the internal focusing, no recalibration of the gimbal is required each time the image angle is changed.
Excellent color reproduction and high resolution performance.
Affordable price and high quality compared to very expensive cinema lenses.
