The award-winning 14-24mm F2.8 is Sigma’s widest-angle zoom lens for mirrorless cameras. It is designed for professional photographers who need uncompromising optical performance across the whole frame and is perfect for landscapes, interiors, weddings, events and architecture.
The lens has an advanced optical design that incorporates 1 FLD elements, 5 SLD elements, and three aspherical elements, including one large-diameter aspherical element. This optical system minimises transverse chromatic aberration and other optical aberrations, and ensures exceptional quality results with remarkable sharpness across the whole frame at all apertures.
The lens delivers outstanding F2.8 brightness throughout the zoom range, perfect for anyone wishing to use the lens hand-held in low light, such as at a wedding. At the rear of the lens a filter holder allows for back-end filters to be added, such as NDs.
The exceptional build quality of the 14-24mm F2.8 DG DN is exactly as you’d expect on an Art line lens, both in the materials used, the overall ergonomics and the quality of craftsmanship. The exterior barrel is made of a polycarbonate called Thermally Stable Composite (TSC). Not only is this very strong and light, but it has a similar thermal expansion rate to aluminium. This ensures that the interior aluminium parts behave in the same way as the external polymer-based parts as temperatures change.
The zoom and focus rings are rubberised for easier operation, and both are internal, meaning the lens never changes length. This makes it ideal for use on a gimbal as the centre of gravity remains fairly constant.
The fixed petal-type lens hood is strong and sleek and protects the bulbous front element from damage if dropped.
The durable brass mount is surrounded by a rubber seal to help keep out dust and moisture.
Precision brass mount with seal
Protects against dust and moisture.
Made from a strong and light polycarbonate that behaves in a similar way to aluminium.
The bulbous front element and fixed petal hood means the lens doesn’t have a front filter thread, which makes attaching a filter holder more difficult. To get around this, SIGMA has fitted a rear filter holder.
The rear glass filters (available from several filter manufacturers) are about the size of an SD card, so very small and light, and as they’re positioned between the camera and lens, don’t tend to get damaged or dirty. It’s also possible to cut filters by hand using gel sheets. A template is included with the lens.
The 14-24mm F2.8 DG DN | Art delivers outstanding optical quality, with excellent rendering of detail right into the corners at all focal lengths and at all apertures.
The lens has an advanced optical design made up of 18 elements in 13 groups, including 3 aspherical elements, 5 SLD elements and 1 FLD element. This ensures razor-sharp results and helps to eliminate chromatic aberration, flare, distortion and vignetting.
Advanced optical coatings reduce flare and ghosting when working in bright direct sunlight, creating high-contrast images with rich colours and strong blacks
The constant F2.8 aperture bring two key advantages. The first is faster shutter speeds, which makes it easier to shoot hand-held in low light conditions without the risk of camera shake.
The second is a shallow depth-of-field, which means blurry background when there is an in-focus foreground subject.
SIGMA has an impressive range of full-frame wide-angle lenses for mirrorless cameras. In fact, SIGMA has been highly innovative in the development of wide-angles for many years. The 14-24mm offers very impressive image quality, zoom flexibility, a moderately fast aperture and a rear filter holder. Another highly capable option is the 20mm F1.4 prime, which has a very fast F1.4 aperture, rear and front filter functionality, an aperture ring and a Manual Focus Lock function.
All Sigma cameras and lenses are designed, manufactured and assembled at our sole factory at Aizu in Japan. This domestic production model is unusual in today’s industry, with most imaging companies opting to outsource to other countries to reduce costs. But SIGMA believes that keeping virtually all manufacturing, processing and assembly in Aizu is essential for creating innovative, carefully thought-out and impeccably constructed products that meet the high standards demanded by professional photographers and film-makers around the world.
Sigma chose Aizu as its main production base in the early 1970s. Situated at the base of Mount Bandai in the Fukushima Prefecture, about four hours’ drive north of Tokyo, Aizu has an abundance of very clean water from mountain streams, which is essential for grinding and polishing lenses. Sigma’s founder, Michihiro Yamaki, was also drawn to this area for its workforce, who have a reputation for their craftsmanship, work ethic and attention to detail. Mr Yamaki’s son, Kazuto Yamaki, now the owner and CEO of SIGMA Corporation, has the same unwavering commitment to keeping production in Japan.
Today Sigma’s factory is more than 50,000 square feet in size, and packed full of some of the most advanced optical manufacturing technology in existence. So when you buy a Sigma camera or lens you can be sure that virtually every single component part has been manufactured and assembled by SIGMA, in Japan, with the greatest level of care and attention. We hope you enjoy using our products.
If you want to see how a particular SIGMA lens or camera performs, why not test drive it with our SIGMA Select hire service. Available for selected SIGMA lenses, short-term loans are free of charge (including shipping), with a small fee if you want to test it for longer. Refundable deposit required. Subject to availability.

A special coating applied to the front element to help repel water and oil.
This suppresses flare and ghosting by minimising reflections within the lens, ensuring punchy, high-contrast results. All lenses in the current Sigma range feature this technology.
This allows filters to be added at the rear of the lens. The filters are about the size of an SD card, and can be purchased or cut out from a sheet using a special template. Because these filters aren’t open to the elements they stay clean, and are much easier to carry around.
Internal focus or an inner focus system means the lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel. This helps keep the centre of gravity of the lens more constant when changing focus.
The lens has an image circle large enough to be used on a full-frame camera. It can also be used on cameras with a smaller ‘crop’ sensor, provided the mount is compatible.
The mount is the part of the lens that attaches to the camera body. A coated brass mount is used for strength, and is surrounded by a rubber seal to keep out dust and moisture.
Found on the barrel of some Sigma lenses, the AFL button can be assigned to various functions to widen the range of operations available on the lens (available functions depend on the camera model).
This switch toggles between autofocus and manual focus.
The diaphragm is constructed of 11 rounded blades for a circular aperture opening and round out-of-focus highlights.
