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.
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
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.
* Only on compatible cameras. Available functions may vary depending on the camera used.

Inner focus system
To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.
To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.
The lens is capable of smooth, quiet and high-speed AF made possible by a stepping motor, as well as supports Face/Eye Detection AF and video AF.
Compatible with Lens Aberration Correction
Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.
*Function available on supported cameras only. Available corrections or auto correction functionality may vary depending on the camera model.
*On cameras where lens aberration correction is controlled with 'ON' or 'OFF' in the camera menu, please set all aberration correction functions to 'ON'(AUTO).
Super Multi-Layer Coating
SIGMA's own Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections with in the lens. All lenses in the current SIGMA range feature this original technology. In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, SIGMA's Super Multi-Layer Coating is highly ef fective, assuring images of outstanding contrast.
Nano Porous Coating
The super multi-layer coating is combined with SIGMA's unique coating technology "NPC (Nano Porous Coating)". The lens has been designed to be less susceptible to strong incident light such as backlight.
"NPC (Nano Porous Coating)" incorporates porous silica as the coating material. The porous silica layer has nano-sized holes with air inside. Having holes of this size enables a large reduction in the refractive index, allowing the reflectance to be lowered more than conventional anti-reflective coatings. As a result, reflected light causing flares and ghosting is sharply reduced, achieving clear image quality.
Water and oil repellent coating
Incorporates a water and oil-repellent coating that allows water to be wiped away easily and prevents oil and fat from sticking to the surface, even in challenging shooting conditions. At the same time, the maintenance of the lens surface becomes easier.
Aperture ring
Aperture ring, designed to help users work intuitively
Aperture ring click switch
Mounted with a de-click function for removing clicks by the aperture ring click switch, enabling seamless operations that are especially useful such as during video shooting.
Aperture ring lock switch
A ring lock system to prevent from unintended movement of the aperture ring during shooting.
AFL button
the AFL button can be assigned with various functions widens the range of operations available on the lens.
MFL switch
The MFL (Manual Focus Lock) switch disengages the focus ring on the lens. After manually focusing the lens to the desired position, set the MFL switch to 'LOCK' in order ]to disengage the focus ring.
This prevents the focus of the lens from being moved by accident (such as when attaching a lens heater or changing the composition) and causing out of focus images. The focus ring can still be rotated but will have no effect.
* Please note that some camera bodies may continue to AF even if the MFL switch is set to 'LOCK', or allow AF temporarily even when the camera has been set to MF, and shift the focus when the MFL switch is set to 'LOCK'.
Rear filter holder
The rear filter holder allows the attachment of a sheet-type filter to the rear part of the lens.
Trace the shape on a sheet filter using the guide plate and cut it out for use.
Focus Mode Switch
Using this swich, it is possible to switch the focus mode between AF and MF.
Dust and Splash Resistant Structure
This lens features a highly effective dust and splash resistant structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection.
*Although this construction allows the lens to be used in light rain, it is not the same as being waterproof, so please prevent large amounts of water from splashing on the lens. It is often impractical to repair the internal mechanism, lens elements and electric components if they are damaged by water.
