Key Features
An updated
classic, designed for more intuitive and interactive use, the Canon
EF-mount Tokina atx-i 11-20mm f/2.8 CF is an ultra-wide zoom
that is ideal for landscape, architecture, interior, and astrophotography
applications. Its bright f/2.8 constant maximum aperture affords consistent
brightness throughout the zoom range and benefits working in available lighting
conditions. 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 color 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 an internal focusing design is used for responsive focusing performance.
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-molded 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 color fringing and chromatic
aberrations throughout the zoom range for greater clarity and color accuracy.
Anti-reflective
multi-layer coated elements suppress flare and ghosting for improved contrast
and color 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
top 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 the lens.
