The Sigma 1.4/24mm DG HSM is a bright wide-angle lens for full-frame cameras, featuring imaging performance that Sigma claims is on a whole new level. It is designed to offer the highest optical performance in its class and is ideal for landscape, indoor, and astrophotography. Customization and flexible adjustment options are available through the optional Sigma USB Dock, which also allows for firmware upgrades for this and other Sigma lenses. Drawing on their experience and design expertise, and complemented by knowledge gained from the development of the Sigma 1.4/35mm DG HSM | Art and the 1.4/50mm DG HSM | Art, Sigma has successfully minimized sagittal coma, chromatic aberration, distortion, and vignetting in the new 24mm lens to achieve exceptionally high optical performance with virtually no imaging errors or distortions. This lens provides the best possible performance when photographing a variety of subjects, such as cityscapes, mountain ranges, and starry night skies that require high imaging performance, as well as indoor shots in low light or images with a soft bokeh.
