Tokina Adds FíRIN 20mm Autofocus Lens for Sony E-Mount Cameras

Tokina expands its FíRIN E-mount line with new autofocus lens for Sony cameras. 

Now the second prime announced in Tokina's FíRIN series of dedicated E-mount lenses, the FíRIN 20mm F2 FE AF shares the same optical design as the original FíRIN 20mm F2 FE, a manual focus lens. Rather than a replacement, the new lens provides Sony alpha shooters an alternative with features dedicated to autofocus.

Inside, the autofocus system is built on a ring-type ultrasonic motor and a GMR sensor for silent, fast focusing. Tokina also says it will be fully compatible with Sony's Fast Hybrid AF and AF function settings that will provide "the same AF the same AF performance as with common E-mount AF lenses." Additionally, you'll be able to fine manual focus adjust and take advantage of the In-Body Image Stabilization found on Sony alpha cameras. 

Optically, the lens provides a 92.66-degree angle of view using 13 lens elements in 11 groups and adopts two aspherical elements and three Super-low Dispersion elements to reduce spherical aberration, distortion and chromatic aberration. Multi-coatings reduce flare and reflections. The 9 diaphragm aperture blade offers a max aperture of F2 and a minimum of F22. The FíRIN 20mm F2 FE manual focus version does provide a button to de-click the aperture ring.

Since it's optimized for the full frame Sony alpha sensors it will be interesting to see the image results when paired with the fast focus Sony a7r III or the newly released a7 III. If Tokina is spot on in terms of its autofocus comparison it could be a solid choice if you're looking to save some cash. If you're wondering about image quality, most have been comparing it to the ZEISS Loxia line. A quick search will find what you're looking for.

I'll be curious to see the autofocus performance. I haven't been unhappy with Tokina in the past so I'm willing to give this one a chance

When you're writing an article, you should be concerned with answering the first question (or questions) a reader will have. This one fails to do so.

1. When will the lens be available?
2. How much will it cost?

If you don't know, then say, "Pricing and availability date have not been announced," or words to that effect. This tells us that you DID think of the glaringly obvious questions but don't have answers for them.
