Sony FE 20mm F1.8 G Full-Frame Large-Aperture Ultra-Wide Angle Lens
The Sony FE 20mm f/1.8 G Lens is finally Sony's answer to a compact ultra-wide prime with a bright maximum aperture for their full-frame cameras. Sony’s latest optical technology achieves impressive corner-to-corner resolution from a maximum F1.8 aperture in a large-aperture wide-angle prime lens. It is 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 fast and quiet while lending to more responsive control for manual focus operation. The lens is also dust- and moisture-sealed along with a fluorine coating, to support shooting in inclement conditions.
A focus hold button, focus mode switch, aperture ring, and other controls have been designed and positioned for easy operation and a smooth workflow. Alternative functions that support individual shooting needs can be assigned to the focus hold button via the camera body menu settings. While the front lens element is fluorine-coated to repel water and grime, and the lens' dust and moisture-resistant design provide the reliability needed for outdoor use in challenging conditions. Additionally, this lens has been optimized for video with a de-clickable aperture ring and a smooth linear manual focus response.
