The Sigma 23mm F1.4 DC DN Contemporary is a fast wide-angle prime for Sony APS-C mirrorless bodies, giving a 35mm-equivalent field of view. Its f/1.4 aperture, 9-blade diaphragm and 13-element design with 3 SLD and 2 aspherical elements target sharp detail and smooth background blur, and a stepping motor drives quiet inner-focus autofocus for stills and video. It is the widest of Sigma's f/1.4 APS-C primes, alongside the 30mm and 56mm, and competes with Sony's 24mm f/1.8 Zeiss and the 16-55mm f/2.8 zoom on speed rather than flexibility. It suits street, documentary and low-light shooters who want a bright normal-wide lens without a zoom's bulk.

Owners and reviewers rate the 23mm f/1.4 as one of the sharpest fast primes for Sony APS-C, praising its wide-open detail and smooth bokeh. Autofocus is called quick and quiet, and the 35mm-equivalent framing is liked for everyday use. Some note the lack of stabilization and its size next to compact primes.
The Sigma 23mm f/1.4 DC DN Contemporary is a lens for APS-C-format mirrorless Sony E cameras. It gives a field of view similar to a 35mm lens on a full-frame camera. The maximum aperture is f/1.4, and the 9-blade diaphragm is designed to produce rounded bokeh.
The optical design has 13 elements in 10 groups. These include 3 SLD glass elements and 2 aspherical elements. Focusing uses an inner focus system driven by a stepping motor, which is intended for both still photography and video. The minimum focusing distance is 9.9 inches.
The lens supports AF assist functions and lens aberration correction on compatible cameras. It is dust- and splash-resistant and has a brass bayonet mount.
