The Sony FE 20mm f/1.8 G lens is a versatile ultra-wide-angle prime lens that combines a bright aperture with exceptional optical performance. Designed for full-frame E-mount cameras, it offers a 20mm focal length, providing a 94° angle of view, which is ideal for capturing expansive landscapes, architectural details, and immersive astrophotography scenes.

The fast f/1.8 maximum aperture allows for excellent low-light shooting and the ability to create images with a shallow depth of field, producing smooth and pleasing bokeh. The lens's optical design includes 14 elements in 12 groups, featuring two Advanced Aspherical (AA) elements and three Extra-low Dispersion (ED) glass elements. This sophisticated construction minimizes aberrations and distortions, ensuring sharp, high-contrast images with accurate color reproduction.

Autofocus performance is swift and silent, thanks to the two XD (eXtreme Dynamic) Linear Motors, making it suitable for both still photography and video applications. The lens also includes a customizable focus hold button and a manual aperture ring with a de-click switch, providing greater control and flexibility for videographers.

Built to withstand the rigors of professional use, the lens boasts a dust- and moisture-resistant construction, allowing for reliable operation in various environmental conditions. Its compact and lightweight design makes it an ideal companion for travel and on-the-go photography.
