Description — Tokina 20mm f/2 AF
The Tokina FiRIN 20mm f/2 AF Prime Lens is built for Sony E mount mirrorless cameras and covers a full-frame image circle. At a fixed 20mm focal length, it falls squarely in the wide-angle category, making it a strong choice for landscapes, architecture, and any scenario where a broad field of view is needed. The f/2 maximum aperture gives photographers access to a larger light intake compared to slower wide-angle options, which is especially useful when shooting in dimly lit environments.
Both autofocus and manual focus are supported, offering shooting flexibility across different use cases and styles. The lens accepts 62mm front filters, a standard size that makes it easy to pair with popular filter systems. Weighing 490g, it has a reassuring heft that suggests solid construction.
Note that image stabilization is not included, so shooters relying on stabilized output should ensure their Sony body provides in-body stabilization support.
