The Sigma 20mm f/2 DG DN Contemporary Lens for Sony E-mount mirrorless cameras are designed to provide excellent edge-to-edge sharpness in a stylish all-metal design. The high-quality, wide-angle prime lens is ideal for photographing landscapes, cityscapes, handheld vlogging, and video streaming, and it offers a bright f/2 maximum aperture to ensure that you can photograph in really low-light conditions.

The lens consists of one SLD glass element and one FLD glass element to ensure correctness of chromatic aberration, and three high-precision aspherical elements to reduce the total size and weight of the lens. To ensure spectacular autofocus, the lens features a stepping motor for quick, accurate, and quiet AF performance.
