Product Features

High optical performance and large aperture F1.4 brightness, yet compact enough to be carried around every day

The perfect wide-angle lens for APS-C mirrorless cameras joins the Contemporary line!

With an easy-to-use angle of view equivalent to 35mm (*35mm film format equivalent), high optical performance, large-aperture F1.4 brightness, and a compact, lightweight lens body, the Contemporary line is the perfect lens for APS-C mirrorless cameras.
The experience Sigma has accumulated in the Contemporary line has resulted 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 provided by the brightness of F1.4. The lens demonstrates its descriptive power in a wide range of applications, including landscapes, portraits, and table photography.
In order to take advantage of the high mobility of mirrorless cameras, the compactness of the lens body was also pursued. The SIGMA Contemporary lineup includes several compact and lightweight F1.4 single focal length lenses in the APS-C format, making them surprisingly compact to carry around.
You want to keep your equipment light and small, but not compromise on descriptive performance. This lens is sure to meet those desires and will be a lens that you will find hard to get rid of.

1. Large aperture F1.4 brightness and excellent resolution from wide open

The SIGMA 23mm F1.4 DC DN Contemporary has an easy-to-use angle of view equivalent to 35mm in the 35mm format, as well as the brightness of a large F1.4 aperture and high image rendering 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. In the palm-size compactness of a mirrorless camera, you can enjoy the rich descriptive power that only a mirrorless camera can offer. Careful measures to prevent flare and ghosting enable clear images even in backlit environments.

2. 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 340g, length of 76.9mm, 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 of both excellent optical performance and compactness based on the latest optical and mechanical design. The AF drive system uses a quiet, high-speed stepping motor. The latest algorithm enables quick focusing for lightweight shooting.

Linear focus is supported for L-mount lenses

The L-mount model can switch to “Linear Focus,” in which the focus shifts in a fixed amount according to the rotation angle of the focus ring.
*Only for compatible L-mount camera bodies.

3. Wide selection of F1.4 single focal length lenses for APS-C mirrorless cameras

The SIGMA Contemporary line offers a wide variety of F1.4 single focal length lenses for APS-C format cameras. 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.
