This versatile wide-angle prime for full-frame cameras is perfect for a wide range of photo and video applications, including environmental portraits, landscapes, night sky and street photography. The lens boasts an ultra-fast maximum aperture of F1.4, which ensures fast shutter speeds in lower light conditions, as well as a very shallow depth-of-field that helps isolate the subject from the background.
The advanced optical design includes two FLD, three SLD and three aspherical elements, which help reduce chromatic aberration and ensure pin-sharp images across the whole frame at all apertures. The lens also features a Hyper Sonic Motor (HSM) for fast and quiet autofocus, and a durable brass bayonet mount.
The exceptional build quality of the 28mm F1.4 DG HSM is exactly as you’d expect from an Art-line lens, both in the materials used 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 and the exterior TSC parts behave in a consistent way as temperatures change.
The focus ring is rubberised for easier operation and focusing is internal, meaning the lens never changes length. This makes it ideal for use on a gimbal as the centre of gravity remains relatively constant.
To reduce flare and ghosting in bright sun, and to help protect the front element from damage if dropped, the lens has a robust petal-type lens hood.
The durable brass mount is surrounded by a rubber seal to help keep out dust and moisture.

The 28mm F1.4 DG HSM | Art produces images with outstanding optical quality, with excellent rendering of detail across the whole frame at all apertures.
The lens has an advanced optical design made up of 17 elements in 12 groups, including 3 aspherical elements, 3 SLD elements and 2 FLD elements. This ensures razor-sharp results and helps to eliminate chromatic aberration, flare, distortion and vignetting.
An advanced Super Multi-Layer Coating on the surface of the elements reduces flare and ghosting when working in bright direct sunlight, creating high-contrast images with excellent colour saturation and strong blacks.
Owing to its F1.4 aperture and wide angle-of-view, the 28mm is a superb lens for interior photography. It is a very popular option with professional wedding photographers, who need to be able to shoot hand-hand in dark conditions.
The wide aperture also means a shallow depth-of-field that helps to separate the subject from the foreground or background.
The 24mm F1.4 and 28mm F1.4 are full-frame Art primes that offer a moderately wide angle-of-view. They are both very versatile optics that are commonly used by street, wedding, landscape and portrait photographers. Both have removable petal-type hoods and a front filter thread. The 28mm is 200g heavier and slightly longer.
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.
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.
Sigma’s Hypersonic Motor (HSM) uses ultrasonic waves to drive the autofocus mechanism. It is extremely quiet, fast and accurate, so is well suited to a wide range of photo and video applications.
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 lens has a filter thread around the front element onto which filters and filter holders can be attached.
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.
This switch toggles between autofocus and manual focus.
The diaphragm is constructed of nine rounded blades for a circular aperture opening and round out-of-focus highlights.
