Optical Design: The Tokina atx-m 11-18mm F2.8 Sony E-mount 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. Its optical elements including the front glass are fully multi-coated with Tokina's original blend formula to minimize ghosts and flares to an unprecedented level. Furthermore, Being a super wide angle lens, the Tokina atx-m 11-18mm F2.8 performs impressive low distortion - a great feature for shooting interiors or architecture. Fast f/2.8 Aperture: The Tokina atx-m 11-18mm F2.8 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.
