Tokina has officially announced the AT-X 11-20mm f/2.8 lens.
The lens is an update to the 11-16mm Pro DX-II lens, expanding the telephoto side of the lens to 20mm and refining the optical design.
The new proprietary optical design uses a total of three aspherical lens elements, two all glass molded and one P-MO hybrid, to achieve excellent contrast and sharpness as well as correct spherical aberrations. The AT-X 11-20mm also 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 make viewing and auto focus possible in lower light situations but still maintaining a reasonable size and weight. This lens also uses common sized 82mm filters so use of a CR-PL filter is possible. Tokina’s exclusive One-touch Focus Clutch Mechanism allows the photographer to switch between AF and MF by snapping the focus ring forward for AF and back toward the lens mount for manual focusing.
Pricing and availability is yet to be announced. For more information, take a look at the Tokina website.
