Ideal for close-up subjects, the Tokina atx-i 100mm f/2.8 FF Macro Canon EF Mount is a short telephoto macro lens, offering a life-size, 1:1 maximum magnification along with an 30 cm 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 multilayered 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.
To achieve an exceptional optical performance demanded for ultra wide angle zoom lens in still and video shooting purposes, two aspherical glass elements and two Super-Low Dispersion glass elements were used in order to minimize distortion, manage spherical aberration and astigmatism while achieving excellent edge-to edge resolution and contrast of the entire image. Great efforts were done to control light fall-off at all focal lengths.
The front of the lens has a 55mm filter threads which extends during the focusing but does not rotate. This allows different filters including polarizers to be used for landscape or product photography. A focus range limiter switch on the side of the lens locks the lens focus into or out of the macro focusing range to avoid excessive AF hunting.
