The FíRIN 20mm f/2 FE MF Lens from Tokina is a wide-angle prime lens specifically designed for multimedia applications and is compatible with full-frame Sony E-mount mirrorless cameras. Its ultra-wide perspective is enhanced by an advanced optical configuration that includes three super-low dispersion elements and two aspherical elements, effectively minimizing both chromatic and spherical aberrations. To further improve image quality, a multi-layer coating has been applied to mitigate lens flare and ghosting, resulting in enhanced contrast and color accuracy. The lens features a manual focus mechanism that allows for precise adjustments when photographing subjects as close as 11 inches. Additionally, the manual aperture ring can be de-clicked, facilitating smooth and silent aperture changes, which is particularly beneficial for cinematic applications. The mount design also incorporates electronic contacts, enabling efficient communication of distance and aperture data to the camera body, thereby supporting the use of focusing aids, in-camera image stabilization, and an electronic viewfinder distance scale.

• Wide-angle prime lens is designed for full-frame Sony E-mount mirrorless cameras, and can also be used with APS-C models where it provides a 30mm equivalent focal length.
