Leaving the honorable AT-X abbreviation, the letter "i" was newly added. "i" stands for "interactive", implying mutual communication between photographer and the lens. This is our believe that this series will provide a tight bond between photographer and the lens in order to capture in the image that the photographer sees around. Exterior, specifications and performance of Tokina's popular and well acknowledged so far AT-X PRO lenses are reconsidered with the contemporary cameras in mind and launched under atx-i brand. The Tokina atx-i 100mm F2.8 FF MACRO is a compact medium tele macro lens for full frame format film and digital SLR cameras. Being light-weight, compact, performing high resolution, fast aperture, low distortion, low falloff and beautiful soft bokeh this lens is extremely attractive tool for macro, portraits, landscapes, street art, commercial and general purpose shooting.

Optical Performance

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.

Mechanics

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.

The direction of the manual focusing ring matches the proprietary direction of Nikon and Canon lenses. The Tokina atx-i 100mm F2.8 FF MACRO Nikon F mount is equipped with manual aperture ring based on Ai AF Nikkor D-Type* lens standard that allows to use this lens with wide variety of cameras including old Nikon film cameras.

When used with Nikon DSLRs that do not have a focus motor in the camera body like D3000 and D5000 series only MF mode is available.
