Tokina AT-X 14-20mm f/2 PRO DX Lens for Canon EF

Description

A fast wide-angle zoom for Canon EF mount APS-C-format DSLRs, the AT-X 14-20mm f/2 PRO DX Lens from Tokina spans a concise 22.4-32mm equivalent focal length range while retaining a bright, constant f/2 maximum aperture. Ensuring a high degree of sharpness and clarity throughout the wide-angle range, the optical design features an array of aspherical and Super Low Dispersion elements to minimise chromatic and spherical aberrations. A multi-layer, anti-reflective coating has also been added to individual elements to suppress flare and ghosting for increased contrast and colour fidelity when working in strong lighting. In regard to handling, an internal focusing design enables quick, accurate autofocus performance that can quickly be overridden for manual control using the One-Touch Focus Clutch Mechanism. Well-suited to working in a variety of situations, the variety of wide-angle perspectives and bright maximum aperture are especially beneficial to landscape, reportage, and other environmental photography applications.
