Sigma 24mm F2 DG DN Contemporary Lens (Sony E)

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. 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.  I-series lens emphasizes a sleek and stylish physical design built to the same operational standards of Sigma's Cine lenses, including a mechanical aperture ring, knurled metal components, and various switches and tactile controls for intuitive operation. Bright f/2 maximum aperture strikes an ideal balance between speed and size and manages to maintain a compact physical profile while also offering low-light performance and depth of field control. The rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
