It is a complex, state-of-the-art zoom containing 13 elements in 11 groups, including dual aspheric elements, a large P-MO element, and a pair of all-glass molded low-dispersion (SD) elements for minimal chromatic and spherical aberrations, minimal distortion, and maximum overall sharpness, especially along the edges. The front element also features a waterproof coating for easy cleaning.
In addition to a fixed, f/2.8 maximum aperture throughout the zoom range, Tokina’s new lens also features a one-touch AF/MF clutch, along with a snap-back focus ring for quick and easy switching between auto and manual focusing. If your forte is architecture, landscapes, or astrophotography, Tokina’s new 11-16mm atx-i CF ultra-wide zoom is well worth a closer look.
