Description

Overview

The FíRIN 20mm f/2 lens is a compact form-factor super wide angle manual prime lens compatible with full-frame E-mount Sony mirrorless cameras.

Optics

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.

Coatings

Anti-reflective coatings play an important role in the optical performance of the lens. In addition to the fact that all glass elements of the FíRIN 20mm f/2 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.

Communication

Being a fully manual lens with a large focus ring, aperture ring and depth of field index bar, the ability to simultaneously transfer distance and aperture status to the camera give you full advantage to use the latest features of the α7 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.

Construction

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 f/2 to enjoy beautiful bokeh.

Cinematography

FíRIN is not only for photography. With a press of the De-Click button on the aperture ring the lens de-clicks the aperture mechanism making it suitable for cinema/video use.

Note: FíRIN series lenses are developed and manufactured in accordance with Sony-licensed specification.
