A compact, high-quality, wide-angle prime, the Sigma AF 20mm f/2 DG DN Contemporary Lens For L-Mount provides excellent edge-to-edge sharpness in a stylish all-metal design. An ideal lens for landscapes, cityscapes, handheld vlogging, and video streaming, the lens provides a modestly bright f/2 maximum aperture for low-light performance and shallow depth of field control. Additionally, its fast maximum aperture makes it a natural choice for night sky and astrophotography. The lens is constructed with one SLD glass element and one FLD glass element to correct chromatic aberration. It incorporates three high-precision aspherical elements, which reduces the total size and weight of the lens. Regarding handling and focus, this lens features a stepping motor for quick, accurate, and quiet AF performance that suits both photo and video applications.
