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

Stunning power of the Art series lens in a compact body:
Explore the versatile potential of "24mm F1.4" with SIGMA

Featuring a very large maximum aperture of F1.4, outstanding suppression of optical aberrations as well as a wealth of thought-out features, the SIGMA 24mm F1.4 DG DN | Art enables photographers to capture breathtakingly clear images with ease even in the most demanding lighting conditions. The versatile viewing angle of 24mm and the luxurious brightness of its F1.4 maximum aperture make this lens the perfect choice for all possible situations, from casual snapshots taken indoors to architectural photographs and even nightly astrophotography. The outstanding image quality achieved by its dedicated mirrorless optical design and the use of each glass element and optimal part resulted in a thorough suppression of optical aberration such as sagittal coma flare to ensure peak performance in every part of the image, within a compact and lightweight body. Additional features such as a front filter thread, rear filter holder and useful buttons such as the newly introduced MFL (Manual Focus Lock) switch further expand the possibilities and versatility of the lens. The SIGMA 24mm F1.4 DG DN | Art brings the power and pleasure of an astrophotography lens into everyday situations.

Features

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 new MFL (Manual Focus Lock) switch

A new MFL function to disable the focus ring operation is available. When the MFL switch is set to “LOCK”, the focus ring operation will be disabled.
In case of astrophotography, the distance to the subject does not change and it is necessary to fix the focus after manual focus adjustments have been made. This is to prevent the focus ring from accidentally being moved, which would cause out-of-focus images. In the past, it was left to the user to invent ways of achieving this, such as using tape to hold the focus ring in position. This was not ideal due the tape’s adhesive strength decreasing when temperatures drop.
The MFL function solves this inconvenience.

Support front and rear filters

The lens also comes with a rear filter holder, allowing photographers the freedom to combine multiple filters to suit a huge variety of shooting situations for near-unlimited creative potential at an ultra-wide viewing angle—for example, using a front filter to reduce light pollution and a softening filter on the rear to take impressive, sharp photographs of nightly landscapes with star-filled skies.

Dust- and Splash- Resistant Structure

The dust- and splash-resistant structure* 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.

  • * Although this construction allows the lens to be used in light rain, it is not the same as being waterproof.

Thoughtful features

1 Focus mode switch
2 AFL button
3 MFL (Manual Focus Lock) switch
4 Aperture ring click switch

5 Lock mechanism
6 Aperture ring lock switch

Thoughtful features such as a focus mode switch, a freely configurable AFL button* 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.

WR CERAMIC PROTECTOR 72mm

With many applications in aerospace and other industries, glass ceramics is an extremely tough type of crystallized glass that serves as the foundation for Clear Glass Ceramics. While featuring the high transmittance required of optical devices, this advanced new material combines greater hardness than chemically strengthened glass and greater flexibility than sapphire crystal glass. These qualities make Clear Glass Ceramics the ideal material for protective lens filters.
