Ideal for close-up subjects, the Nikon F-mount Tokina atx-i 100mm f/2.8 FF Macro is a short telephoto macro lens, offering a life-size, 1:1 maximum magnification along with an 11.8" minimum focusing distance. This lens uses a flat-field optical design to yield realistic rendering, void of field curvature, as well as high sharpness and clarity throughout the focusing range. A multi-layer coating has also been applied to reduce lens flare and ghosting for increased contrast and improved color fidelity. Complementing the optics, this lens features a One-Touch Focus Clutch Mechanism for fast changing between AF and MF settings, and a focus range limiter switch helps to achieve faster focusing performance at close-up distances.
