Tokina FiRIN AF 20mm F/2.0 FX Sony E-mount camera lens

Wide-angle prime for Sony E-mount

The Tokina FiRIN AF 20mm F/2.0 FX is a new autofocus prime lens built for Sony full-frame and APS-C mirrorless cameras. Its f/2.0 maximum aperture gathers ample light for low-light photography and video work. The optical design uses two aspherical elements and three Super-low Dispersion glass elements to control aberrations across the frame. A ring-shaped ultrasonic motor drives fast, quiet autofocus with GMR sensor precision.

Suited to environmental and astro shooters

This lens suits photographers who need a bright, super-wide perspective for landscapes, architecture, interiors or night-sky scenes. The silent motor and full Hybrid AF support also serve video creators tracking moving subjects. Buyers who require zoom versatility or a longer focal length for portraits or sports should look at alternative optics.

Build-around notes for mirrorless kits

The lens mounts directly to any Sony E-mount body and communicates EXIF data for in-camera shading, distortion and lateral chromatic aberration correction. It works with in-body image stabilisation, Direct Manual Focus and MF Assist without adapters. The 20mm focal length leaves room in a kit for a standard zoom or telephoto prime to cover tighter compositions.
