Presenting an ultra-wide field of view, the Sony FE 20mm f/1.8 G is a sleek prime lens characterized by its portability, advanced optical design, and intuitive handling.

The optical design incorporates a pair of aspherical elements and three extra-low dispersion elements to greatly reduce a variety of aberrations and distortion. A Nano AR Coating has also been applied to further reduce surface reflections and flare for improved contrast when working in bright and backlit conditions. Benefitting the optics, this lens also sports a dual XD Linear Motor system that is quick and quiet, and also lends more responsive control for manual focus operation.

The lens also has a dust- and moisture-sealed design, along with a fluorine coating, to support shooting in inclement conditions.
