Stellar results, anywhere, anytime. An astrophotography lens for everyday use.

Capture breathtakingly clear images with ease even in the most demanding lighting conditions, made possible by the very large maximum aperture of F1.4 and outstanding suppression of optical aberrations and dedicated mirrorless optical design. The versatile viewing angle of 24mm and the luxurious brightness of its F1.4 maximum aperture make this lens the perfect choice for shooting anything from casual indoor snapshots to architectural photographs and even astrophotography. The SIGMA 24mm F1.4 DG DN | Art brings the power and pleasure of an astrophotography lens into everyday situations.


Wide viewing angle and astrophotography-level optical performance

The fantastic optical performance of the SIGMA 24mm F1.4 DG DN | Art is powered by the optimal arrangement of 17 elements in 14 groups, including two FLD, one SLD and four aspherical glass elements. The successful suppression of optical aberrations such as sagittal coma flare, which cannot be corrected by the camera, contributes to lens’ clear and accurate point-image reproduction capabilities in every part of the frame. Other unsightly effects such as ghosting or flares are minimized by its state-of-the-art optical design, and the use of Super Multi-Layer Coating and Nano Porous Coating (NPC) allow the SIGMA 24mm F1.4 DG DN | Art to deliver visual punch even in backlit conditions and near maximum aperture. Its power to render clean and accurate images in any situations make this lens ideal for everyday use as well as technically demanding genres like astro-, landscape and architectural photography. Experience the power and joy of one of the most versatile lenses in SIGMA’s Art F1.4 lineup.

Compact for an F1.4 large-aperture, wide-angle lens beyond belief

The SIGMA 24mm F1.4 DG DN | Art delivers its brilliant optical performance in a compact, portable and easy-to-use body. Thanks to an optimal placement of each single part, the use of complex aspherical glass elements, the freedom afforded by the short flange back distance and a fierce fight for every single gram, the lens comes at an astonishingly small size and weight despite its wide viewing angle and large maximum aperture without any compromise of its optical qualities. With its handy dimensions, the 24mm F1.4 DG DN | Art is easy and convenient to use in any given situation, from travel and street photography to night-time photography. The wide viewing angle of its 24mm focal length makes it easy to get everything into the shot without losing focus of the subject – ideal for single or group portraits and documentary photography. The SIGMA 24mm F1.4 DG DN | Art opens up endless possibilities to anyone who values high optical performance, versatility and convenience, from professional photographers to users who are new to a wide-angle prime lens.

Superb build quality with a range of useful features

The SIGMA 24mm F1.4 DG DN | Art is equipped with both a front filter thread and a rear filter holder, as well as a new MFL switch that disables the focusing ring to prevent accidental changes that will be especially helpful when photographing the stars at night. The dust- and splash-resistant structure*1 of the lens itself and the water- and oil-repellent coating of the front element will keep the lens safe and functioning even during shoots in harsher environments. Thoughtful features such as a focus mode switch, a freely configurable AFL button*2 and the aperture ring lock switch to prevent accidental changes further enhance the intuitive and flexible nature of the lens. The petal-type hood has a lock mechanism to prevent unintentional removal. Filmmakers will especially appreciate the fast yet silent autofocus driven by a stepping motor and the aperture ring click switch that allows for smooth aperture control. With its exceptional optical performance and superb build quality, the SIGMA 24mm F1.4 DG DN | Art is the latest result of SIGMA’s relentless, uncompromising pursuit of perfection down to the smallest detail.
