Preserving the Tokina's advanced technology (atx) new series is marked with "m" letter, that stands for "motif" and "mirrorless" - motivation that Tokina provides to photographer for creating unique and breathtaking photos with mirrorless cameras.

The Tokina atx-m 11-18mm F2.8 E features a fast f/2.8 aperture throughout the zoom range, and a 11-18mm (17-27mm in 35mm equivalent) zoom stored in a compact and lightweight body for active hybrid users who shoot stills and video.

The Tokina atx-m 11-18mm F2.8 E features a lightweight (335g) and compact (overall length 74.1 mm) design to match Sony E mount mirrorless cameras. Despite the fact that this is a super wide angle lens, it is so small that it does not give a bulky feel, even when shooting with one hand.

The Tokina atx-m 11-18mm F2.8 incorporates a complex optical design with a well-balanced arrangement of 2 aspherical and 2 super low-dispersion (SD) glass elements to suppress chromatic aberrations and provide rich color reproduction, low distortion and low light fall-off.

The Tokina atx-m 11-18mm F2.8 E features a fast f/2.8 aperture throughout the zoom range for shallower depth-of-field, and 9 blades giving a rounded diaphragm for smooth-edged bokeh in background highlights.

Short minimum focusing distance (MFD) is just 19cm at the widest end, providing advantages in creating unique wide-angle macro images with perspective effects. At an open aperture the image appears more dynamic and 3D looking with front and back bokeh.

The Tokina atx-m 11-18mm F2.8 provides full compatibility with Sony E mount cameras' advanced features, including fast hybrid AF, Image Stabilization, Direct Manual Focus, MF Assist mode, Eye AF and different optical corrections such as shading, chromatic aberration and distortion.

The Tokina atx-m 11-18mm F2.8 incorporates a silent ST-M motor unit coupled with the lens position sensor for fast and precise auto focusing operations in still and video modes.

The lens' firmware can be updated by customers using a USB (Type B) cable.
