23mm F1.4 DC DN

The wide-angle lens ideal for APS-C mirrorless cameras.

High optical performance, F1.4 brightness, and compact enough to carry around every day

With an angle of view of 35mm*, high optical performance, the brightness of 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 is excellent for a wide range of applications, including landscapes, portraits, and tabletop photography. To take advantage of the high mobility of mirrorless cameras, compactness of the lens body was pursued. The 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.

*35mm equivalent

Large aperture F1.4 brightness and excellent resolution from maximum aperture

The lens is composed of 13 elements in 10 groups, including 3 SLD glass elements and 2 aspherical lens elements, to achieve sharp, clear images. It delivers excellent resolving power from the maximum aperture. Furthermore, the large F1.4 aperture allows for large, beautiful bokeh effects. Careful countermeasures against flare and ghosting enable clear shooting even in backlit environments.

Compact body optimized for 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 Japan, has enabled the lens body to achieve the ideal balance between excellent optical performance 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 4 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. The 4 focal lenghts are 16mm, 23mm, 30mm and 56mm.

Support for switching between linear and non-linear focus ring settings (for L-Mount only)

For L-Mount cameras*, it is possible to switch to "linear focus," in which the focus shifts by a fixed amount according to the rotation angle of the focus ring.

*Only for compatible L-Mount camera bodies.
