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 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 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.
*The figures are for L-Mount.
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.
