Sigma 14mm F1.4 DG DN Art lens for Sony FE 

This full-frame, ultra-wide-angle prime for mirrorless cameras is perfect for night sky photography, landscapes, interiors, weddings, travel and architecture.

Its ultra-wide aperture of F1.4 ensures very fast shutter speeds in lower light conditions, as well as a very shallow depth-of-field for pronounced subject separation.

The lens comes with a raft of pro-level features that includes an aperture ring with de-click and lock switches, an AFL button, a lockable lens hood, a rear filter holder, a Lens Heater Retainer and a manual focus lock feature.

• Designed for Astrophotography
• HLA Autofocus Motor
• TS-141 Tripod Socket
• Rounded 11-Blade Diaphragm
• Dust and Splashproof Design

The optical design includes two SLD and three aspherical elements, one of which is the largest double-sided aspherical glass element in Sigma’s history. These advanced optics ensure very minimal chromatic aberration, sagittal coma flare and image distortion, giving highly-detailed images with exceptional sharpness and accuracy from the centre to the periphery of the frame.

Ideal for wider landscapes

With an angle-of-view of 114.2° degrees the 14mm is an ideal landscape lens, particularly when capturing a very wide scene, or to create a sense of depth. At this focal length, the size of foreground objects is exaggerated, so works well for scenes with interesting or dominant foreground.

High-performance optics

The 14mm F1.4 DG DN | Art delivers 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 19 elements in 15 groups, including 4 aspherical elements, 1 SLD element and 3 FLD elements. This ensures razor-sharp results and helps to eliminate chromatic aberration, flare, distortion and vignetting.

Advanced Super Multi-Layer Coatings reduce flare and ghosting when working in bright direct sunlight, creating high-contrast images with rich colours and strong blacks.

Rear filter holder

As the 14mm F1.4 uses a rounded glass element as the front optic, a rear filter holder has been included. Rear 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 easy to cut filters by hand from gel sheets, and a special template is included with the lens.

Outstanding build quality

The exceptional build quality of the 14mm F1.4 DG DN is exactly as you’d expect from 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 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, which can be de-clicked for stepless aperture changes. When put into Auto, aperture is controlled by the camera. A lock switch allows users to lock the ring in Auto or Manual so it’s not accidentally knocked into a different setting

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.

Made in Japan

All Sigma cameras and lenses are designed, manufactured and assembled at their 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.
