The 35mm F1.4 DG DN is one of the best wide-standard primes ever built for full-frame mirrorless cameras. It combines excellent image quality, a fast aperture, rapid autofocus and a highly versatile focal length to make it a great choice for a wide range of photography applications, including portraits, landscapes, street, weddings and travel. The maximum aperture of F1.4 allows photographers to shoot with a very shallow depth-of-field, which helps create subject separation for high impact results. It is an excellent companion lens to the 24mm, 50mm and 85mm Art primes, which also offer F1.4 apertures.
Thanks to its advanced optical design that includes 15 elements in 11 groups, including one F Low Dispersion (FLD) element and four Special Low Dispersion (SLD) elements, image quality is exceptionally high, with pin-sharp results free of chromatic aberration at all aperture settings. The lens also has a Super Multi-Layer Coating to reduce ghosting and flare.
The lens has an aperture ring allowing users to change aperture with the lens rather than the camera if desired. This can be de-clicked and locked.
The exceptional build quality of the 35mm F1.4 DG DN is exactly as you’d expect from an Art-line lens, 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 and the exterior TSC parts behave in a uniform 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 fairly constant.
Towards the rear of the barrel is an aperture ring so that aperture can be changed on the lens, and it has an Auto setting should users prefer to change aperture using the camera.
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 with lock button. A rubberised ring on the hood makes for easier removal and fitting.
The durable brass mount is surrounded by a rubber seal to help keep out dust and moisture.

Protects against dust and moisture.
Made from a strong and light polycarbonate that behaves in a similar way to aluminium.
Focus Mode switch
For changing between AF and MF.
Customisable depending on camera body.
Aperture Click switch
Clicks or de-clicks the aperture ring.
A range of controls on the lens include an AF/MF switch, and a customisable AFL button (depending on camera model).
The lens also has a click/de-click switch so that the aperture ring can be adjusted smoothly rather than in hard stops, which may be useful for film-makers. There’s also a lock switch that keeps the aperture ring in either Auto or Manual. This stops the ring accidentally being knocked out of Auto to F16 during use.
A powerful stepping motor ensure fast, accurate and quiet AF and excellent AF tracking capability.
The 35mm F1.4 DG DN | Art boasts outstanding optical quality, with excellent rendering of detail right into the corners even wide open at F1.4.
The lens has an advanced optical design made up of 15 elements in 11 groups, including 2 aspherical elements, 2 SLD elements, 1 FLD element and 1 ELD element. At the time of release, the 35mm F1.4 was the only SIGMA lens to have ELD technology. These six low-dispersion elements help to ensure razor-sharp results and 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.
At F1.4, the lens is able to collect four times more light than an F2.8 optic, making it perfect for low-light photography such as astro and other night-scapes. The lens can render exceptional star detail even in shorter exposures, and saggital coma flare is very minimal meaning that stars remain as sharp, bright points of light even in the corners.
The front and rear filter options make it easy to attach soft filters and light pollution filters.
SIGMA has two ultra-wide-aperture 35mm mirrorless primes in its range: the 35mm F1.4 DG DN and the 35mm F1.2 DG DN. These are similar in their optical performance, AF speed and external design. The 35mm F1.2 has the faster aperture, although it is 69% heavier than the 35mm F1.4. It also lacks the aperture ring lock switch 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.
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 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.
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.
