SIGMA Unveils the 23mm f/1.4 DC DN APS-C Lens
SIGMA announces the 23mm F1.4 DC DN Contemporary lens, a wide-angle fast-aperture prime lens designed specifically for APS-C mirrorless systems. This lens offers a 35mm field of view equivalency with the 1.5X crop factor applied, and is the fourth fast-aperture F1.4 DC DN Contemporary prime lens, joining the popular 16mm F1.4 DC DN Contemporary, 30mm F1.4 DC DN Contemporary, and 56mm F1.4 DC DN Contemporary for crop-sensor mirrorless systems. The DC DN family 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 340g, length of 76.9mm and filter diameter of 52mm, offering exceptional imaging performance when paired with compact APS-C mirrorless camera along with high-megapixel, full-frame mirrorless cameras in APS-C crop mode. 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 conditions. 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.
Key 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 ghosting and flare 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.
Support for switching between linear and non-linear focus ring settings (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.
- A wide 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 lightweight. By combining them according to your needs, you can build a compact photographic system without compromising on image quality.
