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