The all-new Sigma 50mm F1.4 DG DN | Art is the latest addition to Sigma’s growing line-up of fast-aperture DG DN Art primes. Designed specifically for mirrorless cameras, and available in L-Mount and Sony E-mount, it offers outstanding optical performance, ultra-fast autofocus, and a compact and robust design. Ideal for portrait, wedding, street, landscape and family photography, this lens is a true all-rounder and an excellent option for video as well.

Sigma 50mm F1.4 DG DN Key Features

  • Outstanding optical performance
  • Ultra-fast autofocus
  • Robust but compact design
  • Advanced feature set designed for professional use

Outstanding Optical Performance

Building on the reputation of the existing SIGMA 50mm F1.4 DG HSM | Art as one of the highest-performing standard zooms on the market, this new mirrorless optic delivers even sharper results across the frame, particularly towards the periphery. The lens features an ultra-wide aperture of F1.4, making it ideal for low-light photography and delivering a shallow depth of field for background blur. The bokeh is smooth and attractive, and the out-of-focus highlights are nicely rounded.

Ultra-Fast Autofocus

The SIGMA 50mm F1.4 DG DN | Art is the first DG DN lens in the Art line to incorporate Sigma’s new HLA (High-response Linear Actuator) autofocus motor technology. This ensures fast, accurate and near-silent focusing, with exceptional tracking performance. The new HLA motor allows the use of a single double-sided aspherical element as the focusing lens, delivering both autofocus and optical design benefits.

Robust but Compact Design

The SIGMA 50mm F1.4 DG DN | Art is a light and compact lens that feels well-balanced on a full-frame mirrorless camera. It is dust- and splash-resistant, with a rubber seal around the mount and a water- and oil-repellent coating on the front element. The outer barrel is constructed of TSC (Thermally Stable Composite), ensuring consistent performance in all environments.

Advanced Feature-Set Designed for Professional Use

The lens barrel is equipped with a range of useful functions, including a manual aperture ring, an Aperture Ring Click switch, an AFL button, a Focus Mode switch, and a rubberized focus ring. The lens is crafted using cutting-edge manufacturing technology and is evaluated with Sigma’s proprietary MTF measuring system, ensuring consistently excellent products that photographers can rely on.
