The Tokina FiRIN 20mm f/2 FE AF lens enhances the established wide-angle design by incorporating autofocus, making it a versatile prime lens specifically designed for full-frame Sony E-mount mirrorless cameras. This ultra-wide lens benefits from an advanced optical configuration that includes three super-low dispersion elements and two aspherical elements, effectively managing both chromatic and spherical aberrations. A multi-layer coating has been applied to minimize lens flare and ghosting, thereby enhancing contrast and color accuracy. The lens features a ring-shaped ultrasonic autofocus motor that delivers rapid, precise, and reliable autofocus performance, while also allowing for full-time manual focus control. Furthermore, the mount design includes electronic contacts that facilitate seamless communication of distance and aperture data to the camera body, supporting the use of focusing aids, in-camera image stabilization, and an EVF 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.
- The f/2 maximum aperture benefits working in difficult and low lighting conditions.
- Three super-low dispersion elements help to reduce chromatic aberrations and color fringing for improved clarity and color accuracy.
- Two all-glass precision molded aspherical elements suppress spherical aberrations to minimize distortion and improve overall sharpness.
- Multi-layered coating helps to alleviate lens flare and ghosting when working in strong lighting conditions.
- Ring-shaped ultrasonic autofocus motor, along with a GMR sensor, affords quick, quiet, and responsive AF performance along with full-time manual focus override.
- Internal contacts relay distance and aperture information to the camera body to enable full support of in-camera focusing aids.
- Nine-blade diaphragm contributes to a pleasing bokeh quality.
