Well, that didn't take long. Less than 12 hours after Nokishita shared some leaked photos and specs of the unreleased lens, Tokina has officially announced its latest piece of Sony E-Mount glass: the FíRIN 20mm F2 FE AF.

The new lens is only the second prime lens in the FíRIN series of lenses designed specifically for mirrorless cameras, and it's actually a followup to the first. The original FíRIN 20mm F2 FE was a manual focus lens, and the new AF version uses an identical optical design. But it doesn't so much replace the old lens as sit next to it in Tokina's lineup, giving users "two options ... to choose [from] according to the purpose and style of shooting."

Like its predecessor, the FíRIN 20mm F2 FE AF boasts 13 lens elements in 11 groups, including two aspherical elements and three Super-low Dispersion elements that promise to do away with as much spherical aberration, distortion, and chromatic aberration as possible.

Unlike the manual focus version, this lens features a ring-type ultrasonic motor coupled with a GMR sensor for fast and silent focusing, and Tokina promises full compatibility with Sony's Fast Hybrid AF system and all AF function settings, "providing the same AF performance as with common E-mount AF lenses."

The FíRIN 20mm F2 FE AF lens is tentatively scheduled to arrive at the end of April for Japanese customers, and end of May worldwide, but if you happen to be at CP+ next week, you can check out a prototype of the new lens at Tokina's booth.

No pricing info has been released as of yet.

Press Release

New Tokina FíRIN 20mm F2 FE AF

February 22nd, 2018 – Kenko Tokina Co., Ltd. is proud to announce the new Tokina FíRIN 20mm F2 FE AF, the second prime lens in Tokina’s premium lens series “FíRIN” for mirrorless cameras.


FíRIN 20mm F2 FE AF is the long-awaited autofocus version of the existing FíRIN 20mm F2 FE super wide angle lens for full-frame Sony E-mount. Adopting the same optical design as in MF model, now we offer two options for end-users to choose according to the purpose and style of shooting.

Optical performance

Being optimized for full size camera sensors in terms of size and resolving ability, the optical design adopts 2 aspherical elements and 3 lenses molded from Super-low Dispersion glass to significantly reduce any type of aberration including spherical aberration, distortion and chromatic aberration while assuring high resolution and stunning performance even at wideopen aperture.


Keeping along with the basic development concept of the previous model FíRIN 20mm F2 FE AF is made compatible to autofocus and other functions of the camera providing perfect functionality and usability for the photographer.

Ring-shaped ultrasonic autofocus motor

For AF drive system FíRIN 20mm F2 FE AF adopts quick responsive and silent ring-shaped ultrasonic motor. Coupled with GMR sensor AF performs fast and accurate focusing.

Full compatibility to AF system

FíRIN 20mm F2 FE AF is fully compatible with Fast Hybrid AF system and all AF function settings, providing the same AF performance as with common E-mount AF lenses. Fine manual focus adjustment is also possible.

MF Assist function

Accurate focusing is supported by compatibility to MF Assist function, when fine focusing adjustment is operated by manual rotation of the focusing ring with the simultaneous interlocking with image enlarging function and bar distance display on the monitor.

Optical correction

Due to the data transmittance ability via electric contacts the camera obtains necessary data from the lens chip to correct shading, distortion and lateral chromatic aberrations. Optical corrections can be done by the camera as well.

Image Stabilization

By transmitting focal length data FíRIN 20mm F2 FE AF is able to get maximum use of In-Body Image Stabilization function of the camera.

* When in-built camera flash is used vignetting may occur. Please use external flash.
