  • 17.6-32mm (35mm Equivalent)
  • Aperture Range: f/2.8 to f/22
  • Three Aspherical Elements

Designed for more intuitive and interactive use, the Tokina atx-i 11-20mm f/2.8 CF Lens for Canon EF is an ultra-wide zoom that is ideal for landscape, architecture, interior, and astrophotography applications with APS-C sensor DLSR cameras.

A constant maximum aperture of f/2.8 throughout the entire zoom range achieves great results in low light conditions, enhanced depth of field control and allowing easy manual shooting while maintaining a reasonable size and weight. The optical design incorporates a series of aspherical and low dispersion elements, which suppress a variety of aberrations for improved sharpness and clarity. Individual elements are also multi-coated to resist flare and ghosting for greater contrast and colour accuracy when working in bright or backlit conditions.

Complementing the optics, this lens features a One-Touch Focus Clutch Mechanism for fast-changing between AF and MF settings, and internal focusing design is used for responsive focusing performance.


Key Features of the Tokina atx-i 11-20mm f/2.8 CF Lens for Canon EF

  • Ultra-wide zoom is designed for APS-C-format Canon EF-mount cameras and provides a 17.6-32mm equivalent focal length range.
  • Bright constant f/2.8 maximum aperture affords consistent brightness throughout the zoom range and offers improved control over depth of field.
  • Three aspherical elements, including two glass-moulded elements and one P-MO hybrid element, help control spherical aberrations and distortions for sharper, more accurate rendering.
  • Three SD (super-low dispersion) elements control colour fringing and chromatic aberrations throughout the zoom range for greater clarity and colour accuracy.
  • Anti-reflective multi-layer coated elements suppress flare and ghosting for improved contrast and colour accuracy when working in strong lighting conditions.
  • Silent-Drive focusing Motor (SD-M) pairs with a GMR sensor and an internal focusing design to achieve fast, responsive, and precise performance.
  • One-Touch Focus Clutch Mechanism avails quick switching between autofocus and manual focus settings by either pushing or pulling the focus ring. When set to manual, focus response is especially smooth and benefitted by hard stops at the ends of the focusing range.
  • Water-repellent lens coating makes wiping and cleaning the surface of the front glass element easier.
  • Nine-blade diaphragm contributes to a smooth bokeh quality.
  • Included lens hood blocks stray light from causing flare and also offers some physical protection the lens.

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.

Anti-reflective multi-layer coating improves light transmission and minimizes reflections while newly applied water-repellent coating makes wiping and cleaning the surface of the front glass element easier.

  • 4 Elements in 12 Groups Optical Design
  • 3x Aspherical Glass Elements
  • 3x Super-Low Dispersion Glass Elements
  • Constant maximum aperture of f/2.8
  • Excellent optical performance with great Edge-to-edge sharpness, reduced flares and ghosting plus excellent contrast and improved optical resolution.

For Still Photography

Ultra-wide 11-20mm focal length and a constant maximum aperture of f/2.8 makes this lens an essential tool for architecture & real estate group photos, environmental portraits, landscape and night sky photography.

For Video Content Production

The Tokina atx-i 11-20mm F2.8 CF is made with videographers and filmmakers in mind who shoot both stills and video professionally.

  • Wide cinematic angle enough to feel confident in small places
  • Minimized focus breathing
  • Natural footage - low distortion suitable for panning shots

Mechanics & Electronics

The Tokina atx-i 11-20mm F2.8 CF for Canon EF mount incorporates internal Silent-Drive focusing Motor (SD-M) in combination with precise GMR sensor to allow the lens to AF accurately and fast. One-touch focus Clutch mechanism allows switching between autofocus and manual focus easy. The overall length of the Tokina atx-i 11-20mm F2.8 CF does not change when focusing and zooming thanks to internal focus.

  • Silent-Drive Autofocus Motor + GMR sensor for fast and accurate autofocus
  • One-touch focus AF/MF Clutch Switch
  • Internal Focus & Zoom for easy use of filters
  • Water-repellent coating keeping the front element clean

Sophisticated Design

Devoted to its traditions, Tokina incorporated a lot of 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 contemporary DSLR cameras.

atx-i Series

Leaving the honourable AT-X abbreviation, the letter "i" was newly added. "i" stands for "interactive", implying mutual communication between the photographer and the lens. 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.
