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

Tokina FiRIN 20mm f/2 AF Reviews
Excellent value and tack sharp at f2
Using for landscapes and architectural. Find the distortion minimal, the sharpness even at f2 is excellent. Not very heavy considering the f2 and good feel to the build. No switches or buttons on the lens, but the instant availability of manual override with a wide width focus barrel is very welcome. (Note while the manual states to use Auto AF to enable the manual fine tune, on a Sony A7 series, set to DAF for this to function on demand. )
Excellent Lens
I purchased this lens switching from a Sigma 24mm F1.4 ART and I love the size and weight of this Tokina. The only complaint would be AF motor noise but I already knew that. I wouldn't recommend this lens for video unless you have off camera mic. I loved everything else on this lens from the build quality to image quality.
