Tokina Firin 20mm F/2 FE MF for Sony E Mount - Manual Focus

The Tokina Firin 20mm f/2 FE MF Lens for Sony E-Mount is a full-frame, super wide angle lens that is composed of 13 lens elements in 11 groups. It features two aspherical lens elements and three Extra-Low Dispersion elements that reduce chromatic aberrations. Meanwhile, ghosting and flaring are prevented by its multi-layer coating. Designed for manual focus and aperture control, it is equipped with De-click Aperture function which makes it perfect for video shooting. It also comes with a depth of field index bar for focusing guidance. Amazing out-of-focus effects can also be achieved via the nine-blade diaphragm. Distance and aperture data is provided through the electronic contacts. For further enhancements, the Tokina Firin 20mm f/2 FE MF Lens for Sony E-Mount has a 62mm filter size.

Product Features in Detail

Optical system
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.

Lens coatings
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.

Seamless 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 A7 series such as 5-axis image stabilization, MF assist, and the electronic distance scale.

Sleek, functional design
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.

Lights, camera, action
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.
