The Nikon F-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. The optical design incorporates a series of aspherical and low dispersion elements, which suppress a variety of aberrations for improved sharpness and clarity. 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 performance. Ultra-wide prime designed for DX-format Nikon F-mount cameras, this lens provides a 16.5-24mm equivalent focal length range. Two aspherical elements, including one large-diameter molded element, help control spherical aberrations and distortions for sharper, more accurate rendering. Multi-coated elements suppress flare and ghosting for improved contrast and color accuracy when working in strong lighting conditions. One-Touch Focus Clutch Mechanism avails quick switching between autofocus and manual focus settings by either pushing or pulling the focus ring.
