Tokina FIRIN 20mm F2 FE AF

Name origin

Fírin is a derivative of Fírinne, the Old Irish word for ''truth.'' It means to be faithful to someone or something and represents a promise from Tokina to photographers to help them capture the truth in their images using this groundbreaking new lens.

With Fírin, photographers are able to shoot with confidence, knowing that every image captured with their mirrorless cameras will be its own moment of truth.

The AF version of the existing MF lens helps you capture outstanding photos in many ways.

Highlights

• Full-frame, super-wide-angle lens that mounts on an Sony A7 series body with ideal compatibility in terms of design and form factor.
• Optically, aspherical lens elements are adopted in perfect positions so that any kind of aberration is minimized. Additionally, 3 lenses, formed from super-low dispersion glass, minimize chromatic aberrations.
• The design is dedicated to manual closing as well as cinema enthusiasts, which features a wide manual focus ring, aperture ring, and depth-of-field rotation.
• De-click aperture function is suitable for cinema/video shooting.
• Luxurious use of high-precision Japanese metal parts and mechanisms.

Optics and ease of use

The combination of two all-glass precision-molded aspherical elements and 3 Super-Low Dispersion (SD) glass lens elements enables to greatly reduce aberrations, resulting in higher resolution and contrast.

High-quality finishes and precision engineered metal parts give this lens the performance of premium optics. Attention to detail, finely machined components, excellent optical design and balanced ergonomics result in a lens that is as easy to use and good looking as the images it captures.

Generous coatings

Anti-reflective coatings contribute greatly to a lens' optical performance. While all of the glass elements of the Fírin 20mm F2 have multiple coatings, the rear convex surfaces of the large G1 element are also extremely noteworthy. Even the contact surfaces of the G6-G7 and G10-G11 element combinations have the coatings. Together, these measures reduce reflections and flare to an absolute minimum, while increasing sharpness and contrast.
