Tokina ATX-i 11-16mm f/2.8 CF Lens for Canon EF
The Canon EF-mount atx-i 11-16mm f/2.8 CF from Tokina is a versatile ultra-wide zoom well-suited for landscape, architecture, and interior shooting. Characterized by its bright f/2.8 constant maximum aperture, consistent brightness is afforded 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.
Two aspherical elements, including one large-diameter molded element, help control spherical aberrations and distortions for sharper, more accurate rendering, Autofocus system uses an internal focusing design for quick and responsive 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, the focus response is especially smooth and benefits from hard stops at the ends of the focusing range.
