The Sony FE 20mm f/1.8 G is a compact, high-performance ultra-wide-angle prime lens designed for landscape, astrophotography, architecture, and vlogging applications. Combining a bright f/1.8 maximum aperture with exceptional sharpness and minimal distortion, it delivers stunning image quality across the entire frame—even in low-light conditions. Engineered with two Advanced Aspherical (AA) elements and three ED (Extra-low Dispersion) elements, the lens effectively suppresses chromatic aberration and coma, making it ideal for capturing stars and night skies with pinpoint accuracy. Despite its professional-grade optics, the FE 20mm f/1.8 G remains remarkably lightweight at just 373g, features fast and quiet autofocus powered by dual XD Linear Motors, and includes dust- and moisture-resistant construction for reliable operation in challenging environments. With a customizable focus hold button, smooth manual focus response, and seamless compatibility with Sony’s full-frame E-mount cameras, this G-series lens is the ultimate tool for creators who demand versatility without compromise.
