The 24mm f/1.4 DG HSM Lens is a member of the highly regarded Art line of Sigma‘s Global Vision Series and is characterized by its advanced optical construction and robust physical design. The 15-element-in-11-group optical design is poised to deliver consistent peripheral brightness and sharpness, even when working at the bright f/1.4 maximum aperture. A Super Multi Coating has been applied to lens elements, too, to reduce flare and ghosting for higher contrast and color fidelity. This focusing motor also enables full-time manual focus override at any time just by rotating the focus ring for refined manual control. Additionally, nine rounded diaphragm blades contribute to pleasing out-of-focus quality when working with shallow depth of field techniques. This lens has been designed using an advanced optical structure to achieve both high resolution and sharpness, along with consistent edge-to-edge illumination. A pair of aspherical elements, with one in the rear of the optical design, correct for sagittal coma flare, distortion, and axial chromatic aberration, while also enabling full use of the fast f/1.4 maximum aperture with maintained peripheral brightness and sharpness. A prime wide-angle lens is designed for full-frame Sony E-mount mirrorless cameras, however, it can also be used with APS-C models where it will provide a 36mm equivalent focal length. The integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocusing, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time. The lens is constructed using a Thermally Stable Composite (TSC) material, along with traditional metals, for greater precision and use in wide temperature variations. The outside of the lens barrel is also engraved with the year of production.
