Tokina Fírin 20mm f/2.0 FE AF is a fixed lens which has been designed having in mind a full-frame Sony E system. The first version of the lens had the same parameters but it was not equipped with the autofocus. This version will not disappear from the market but it will be a manual alternative of the lens.
Inside the new lens, we will find an advanced optical system consisting of 13 elements placed in 11 groups. Among them, we will find two aspherical lenses and three super-low dispersion lenses, whose task is to minimize aberration and image distortion. In addition, the lenses have been covered with anti-reflective coatings.
The lens is equipped with the 9-blade aperture, which can be regulated within the scope of f/2 to f/22.

An ultrasonic motor, supported by GMR sensor, is responsible for focusing. As a result, we can enjoy a quick and quiet image re-focusing, from the minimum distance of 28cm.
