AT-X 14-20mm f/2 PRO DX Lens for Nikon F
Wide-angle zoom lens for Nikon APS-C
The AT-X 14-20mm f/2 PRO DX Lens from Tokina is a fast wide-angle zoom designed for use with Nikon F mount APS-C (DX format) DSLRs. It offers a 21-30mm equivalent focal length range combined with a bright, constant maximum aperture of f/2. This combination makes it well-suited to landscape, reportage, and environmental photography.
An internal focusing design ensures autofocus is fast and accurate, and when needed autofocus can quickly be overridden for manual control using the One-Touch Focus Clutch Mechanism. By sliding the focusing ring back or forth, you can quickly change between focusing modes.
Optically it features a 13 elements, 11 groups design that includes one plastic-molded aspherical element, two Super Low Dispersion (SD) glass elements, and two glass-molded aspherical SD glass elements to minimize chromatic and spherical aberrations throughout the zoom range. A multi-layer, anti-reflective coating has also been applied to the individual elements to control flare and ghosting for improved contrast and colour accuracy. Nine diaphragm blades contribute to a pleasing bokeh quality.
