Large aperture F 1.4 brightness and excellent resolution from maximum apertureThe Sigma 23mm F 1.4 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 F 1.4 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 F 1.4 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 camerasTo take advantage of the mobility of APS-C mirrorless cameras, the lens body is compact and lightweight. 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 F 1.4 prime lensesThe Sigma Contemporary line offers a wide variety of APS-C format F 1.4 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. TechnologyInner focus systemTo increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.
Compatible with Lens Aberration CorrectionMatching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality. Super Multi-Layer CoatingSigma's own Super Multi-Layer Coating suppresses flare and ghosting by preventing reflections with in the lens. All lenses in the current Sigma range feature this original technology. In digital cameras, flare and ghosting may also be caused by reflections between the image sensor and lens surfaces. Here too, Sigma's Super Multi-Layer Coating is highly effective, assuring images of outstanding contrast.
Stepping MotorThe lens is capable of smooth, quiet and high-speed AF made possible by a stepping motor, as well as supports Face/Eye Detection AF and video AF. Mount with Dust and Splash Resistant StructureThe lens mount incorporates rubber sealing to protect the mount from dust and water drops
