The new Tokina AT-X 11-20mm F/2.8 PRO DX is
an ultra-wide zoom lens featuring an expanded
zoom range and improved optical performance.
Designed for use with Canon and Nikon DSLR
cameras with APS-C (DX) sensors.
Tokina adds to its family of fast-aperture wide-angle
zooms focused on providing photographers
professional quality optics and construction at an
affordable price. The fast F/2.8 aperture lens offers
an equivalent 16.5-30mm* zoom range.
The new proprietary optical design uses three
aspherical lens elements (2 all-glass molded and 1
P-MO hybrid) to achieve superior contrast,
sharpness, and correct for spherical aberrations.
Additionally, Tokina uses three SD (super-low Dispersion, “FK01” and FK03”) glass elements
to control chromatic aberrations.
This compact ultra wide-angle zoom lens has a bright, constant F/2.8 aperture making
viewing and auto focus possible in low light situations but still maintaining portable size and
