The SIGMA 23mm F1.4 DC DN | Contemporary is a wide-angle fast-aperture prime lens designed specifically for APS-C mirrorless system cameras (DC=APS-C, DN=mirrorless camera system design), delivering high resolution along with beautiful bokeh effects thanks to its F1.4 maximum aperture. This lens has been designed to achieve the highest level of optical performance in the history of SIGMA's DC DN line.

With a field of view equivalent to 35mm on a full-frame camera, the 23mm F1.4 DC DN | C adds this classic focal length to APS-C mirrorless cameras

This is the fourth F1.4 DC DN prime lens, joining the 16mm F1.4 DC DN | C, 30mm F1.4 DC DN | C, and the 56mm F1.4 DC DN | C lens. The DC DN line also includes the 18-50mm F2.8 DC DN | Contemporary Zoom lens.

To take advantage of the mobility of APS-C mirrorless cameras, the lens body is compact and lightweight, with a weight of 330g, length of 78.9mm, and filter diameter of 52mm, offering exceptional imaging performance when paired with compact APS-C mirrorless camera bodies including the Sony a6000 series and Fujifilm X-S10, along with high-megapixel, full-frame cameras in APS-C crop mode such as the 61MP SIGMA fp L.

AF is driven by a quiet, high-speed stepping motor for swift, silent operation for both still and video capture, and excellent flare/ghosting resistance makes it ideal for real-world shooting conditions. The overall optical performance is similar to the 56mm F1.4 DC DN | Contemporary lens and 35mm F1.4 DG HSM | Art lens.

The lens is ideal for landscapes, journalism, everyday photography, and so much more; with a maximum magnification ratio of 1:7.3 and a minimum focusing distance of just under 10 inches. The 9-blade rounded diaphragm allows for creative bokeh effects. The mount is dust- and splash-resistant.

The wide-angle lens ideal for APS-C mirrorless cameras joins the Contemporary line
With an easy-to-use angle of view of 35mm, high optical performance, the brightness of a large F1.4 aperture, and a compact and lightweight lens body, SIGMA's experience accumulated in the Contemporary line has culminated in a lens that is ideal for use with APS-C mirrorless cameras. The lens offers excellent resolution from maximum aperture and the rich bokeh effects thanks to its F1.4 brightness. The lens demonstrates its descriptive power in a wide range of applications, including landscapes, portraits, and tabletop photography. In order to take advantage of the high mobility of mirrorless cameras, compactness of the lens body was also pursued.

The SIGMA's Contemporary lineup includes several compact and lightweight F1.4 prime lenses in the APS-C format, which are surprisingly compact to carry around. If you want to keep your equipment light and small, but not compromise on image rendering performance, this lens is sure to meet your needs, and will be a lens you will never want to let go.

Features

Large aperture F1.4 brightness and excellent resolution from maximum aperture
The SIGMA 23mm F1.4 DC DN | Contemporary has an easy-to-use angle of view equivalent to 35mm in 35mm format, as well as the brightness of a large F1.4 aperture and high descriptive power. The optics is composed of 13 elements in 10 groups, including 3 SLD glass elements and 2 aspherical lens elements, to achieve sharp, clear images. The lens delivers excellent resolving power from the maximum aperture. Furthermore, the large F1.4 aperture allows for large, beautiful bokeh effects. The compact, palm-size body allows you to enjoy the rich descriptive power of mirrorless cameras. Careful countermeasures against flare and ghosting enable clear shooting even in backlit environments.

Compact body optimized for APS-C mirrorless cameras
To take advantage of the mobility of APS-C mirrorless cameras, the lens body is compact and lightweight, with a weight of 330g, length of 78.9mm, and filter diameter of 52mm. At the same time, the quality of the lens body itself has not been compromised. The high-precision machining technology of SIGMA's sole production facility in Aizu, Japan, has enabled the lens body to achieve the ideal balance between excellent optical performance based on the latest optical and mechanical design and compactness. The AF drive system uses a quiet, high-speed stepping motor. The latest algorithm enables quick focusing for easy shooting.

Expands the variety of APS-C format F1.4 prime lenses
The SIGMA Contemporary line offers a wide variety of APS-C format F1.4 prime lenses. All of them share the concept of combining superior resolution with compactness and light weight. By combining them according to your needs, you can build a compact photographic system without compromising on image quality.
