A compact wide-angle prime, the Sony E-mount 24mm f/2 DG DN Contemporary Lens from Sigma provides excellent edge-to-edge sharpness in a stylish all-metal design. An ideal lens for landscape, nature, interior, and architectural photography, 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 of two SLD glass elements and one FLD glass element to correct axial chromatic aberration. The lens also incorporates two high-precision glass-molded aspherical elements, which enable the total weight of the lens to be reduced. In regard to handling and focus, this lens features a stepping motor for quick and quiet AF performance that suits both photo and video applications.
