Sigma 50mm F1.4 DG HSM Art lens - Nikon F

This full-frame standard prime for DSLR cameras is one of the best-respected ultra-wide-aperture 50mm lenses on the market. The standard focal length, which renders images that closely match the perspective of the human eye, makes this a true all-rounder that gives natural-looking results. It’s suitable for a very wide range of photo and video applications, including portraits, weddings, street, landscapes and travel.

The lens’s F1.4 aperture allows photographers to achieve a shallow depth-of-field and work hand-held in low light, and the background blur is smooth and attractive. Optically the lens delivers exceptional sharpness across the frame, even on the highest resolution mirrorless cameras, and colour rendition and accuracy are of the highest level. This makes for characterful and expressive results typical of Sigma’s Art line primes. Used widely by professional photographers, the SIGMA 50mm F1.4 DG HSM is also ideal for casual day-to-day shooting.

High-precision Construction

The superb build quality of the 50mm F1.4 DG HSM is exactly as you’d expect from an Art-line lens, both in its intuitive ergonomics and in the quality of craftsmanship.

The lens’ outer barrel is made of a polycarbonate called Thermally Stable Composite (TSC), which is not only strong and light but 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.

To reduce flare and ghosting in bright sunlight, and to help protect the front element from damage if dropped, the lens has a robust petal-type lens hood.

High-performance optics

The 50mm F1.4 DG HSM | Art for DSLRs 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 13 elements in 8 groups, including 1 aspherical element and 3 SLD elements. This ensures razor-sharp results with very minimal chromatic aberration, flare, distortion and vignetting.

An advanced Super Multi-Layer Coating on the surface of the elements helps to reduce flare and ghosting when working in bright direct sunlight, creating high-contrast images with rich colours and strong blacks.

The durable brass mount is surrounded by a rubber seal to help keep out dust and moisture.

Rich and accurate colour rendition

As is true of all SIGMA Global Vision lenses, the 50mm F1.4 produces images with vivid and true-to-life colours straight out of the camera. This is partly thanks to the exceptional control of flare, which keeps image saturation high.
