The evolution of a classic /
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.

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.

Outstanding build quality /
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.

Professional feature-set /
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.

High-performance optics /
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.

Ideal for landscapes /
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.
