Fírin is a variation of Fírinne, the Old Irish word for “truth,” which was coined during the Gaelic Revival in the late 19th Century. It means, “that which is real.” It signifies “being true to someone or something.” And it represents a promise from Tokina to photographers to help them capture the truth in their images with this revolutionary new lens.
With FíRIN, photographers can shoot with confidence, knowing that every image captured with their mirrorless cameras will be its own moment of truth.
By adopting two all-glass precision molded aspherical elements and 3 Super-low Dispersion (SD) glass lens elements we succeeded in greatly reducing aberrations yielding images higher resolution and contrast. This optical design demonstrates Tokina’s decades of experience and traditions of excellence as an optics manufacturer merged with the application of new technologies.
Anti-reflective coatings play an important role in the optical performance of the lens. In addition to ALL glass elements of the FíRIN 20mm F2 are multi-coated,considerable work has been done with the rear convex surfaces of the large G1 element. This element was very difficult to coat due to its complex shape. The Coatings are even on the contacting surfaces of the element combinations G6- G7 and G10-G11. All these small measures add up to reduce reflections and flare to an absolute minimum while increasing sharpness and contrast.
Being a fully manual lens with a large focus ring, aperture ring and depth of field index bar, the abiility to simultaneously transfer distance and aperture status to the camera give you full advantage to use the latest features of the A7 series such as 5-axis image stabilization, MF assist and the electronic distance scale.
You can get the advantage of both strengths: excellent optical properties of the lens and outstanding camera image processing power.
Exterior & Usability
Carefully crafted high quality finishes and precisely engineered and manufactured metal parts give this lens the feel and performance of a premium optic.
Attention to detail, finely machined and finished component, superb optical design and balanced ergonomics yield a lens that is as easy to use and good looking as the images it creates. Manual focus allows prefocus technique snapshots to be taken with easy using the advantage of the deep depth of field of this super-wide angle lens or open up to F2 to enjoy beautiful bokeh.
FíRIN is not only for photography. With a press of the De-Click button on the aperture ring the lens declicks the aperture mechanism making it suitable for cinema/video use.
