Experience the "I series" philosophy with the Sigma 24mm f/2 DG DN. Built with the same precision-cut aluminum components used in Sigma’s Cine lenses, this lens offers a tactile experience rarely found in modern mirrorless glass. Its fast f/2 maximum aperture makes it an excellent choice for night sky photography, as it is specifically engineered to suppress sagittal coma flare—ensuring stars remain sharp points of light rather than streaks. Optically, the lens is sophisticated, utilizing two SLD elements and one FLD element to correct chromatic aberrations, alongside two high-precision glass-molded aspherical elements that keep the lens body small without sacrificing resolution. The stepping motor provides quiet, high-speed autofocus that fully supports Sony’s advanced Eye-AF and tracking systems. With a manual aperture ring featuring satisfying click stops and a unique magnetic lens cap, this lens is as much a pleasure to handle as it is to shoot with.
