Adding autofocus to the proven wide-angle design, the FiRIN 20mm f/2 FE AF from Tokina is a versatile prime dedicated to full-frame Sony E-mount mirrorless cameras. The ultra-wide perspective is benefitted by a sophisticated optical design, which incorporates three super-low dispersion elements and two aspherical elements to control both chromatic and spherical aberrations. A multi-layer coating has also been applied to reduce lens flare and ghosting for increased contrast and improved color fidelity. Its ring-shaped ultrasonic autofocus motor realizes fast, responsive, and accurate AF performance along with full-time manual focus control. Additionally, electronic contacts are integrated into the mount design to permit seamless communication of distance and aperture information to the camera body in order to support the use of focusing aids, in-camera image stabilization, and an EVF distance scale
