Sigma DG DN 24mm f/2 I Contemporary Lens

All I series lenses have an all-metal construction. The precision-cut aluminium parts not only give the barrel a sleek, stylish finish, but provide superb durability that improves the quality of the entire lens.

The Sigma 24mm F2 DG DN | Contemporary lens combines the highest level of optical performance even at its maximum aperture of F2.

The lens uses two SLD glass elements and one FLD glass element to correct axial chromatic aberration, which is a particular concern with bright lenses. It also incorporates two high-precision glass-molded aspherical elements.

In anticipation of wide-angle lens applications, SIGMA’s optical designers have ensured the lens resolution is extremely high, and is uniform from the center to the periphery of the image. Sagittal coma flare is also well suppressed, giving the lens a high degree of rendering power that makes it ideal for night sky photography.

The AF drive system incorporates a quiet, high-speed stepping motor. This allows you to capture every detail of the spacious 24mm scene with light AF.
