MTF Chart

The MTF (Modulation Transfer Function) is one of the measurements for evaluating a lens’ performance, and it shows how faithfully the contrast of the subject can be reproduced on the image plane. The horizontal axis shows the image height (distance from the center of the image in mm) and the vertical axis shows the contrast value (maximum value is 1).
The closer the 10 line pairs/mm curve is to 1, the higher the contrast and clarity of the lens is, and similarly, the closer the 30 line pairs/mm curve is to 1, the better the resolution and sharpness of the lens is.

*The MTF chart depicts the result at the wide-open aperture.
*For mirrorless lenses that support distortion correction, the horizontal axis shows the image height equivalent to when an L-Mount lens is attached to a Sigma L-Mount camera with distortion correction applied. (The effect of distortion correction may differ depending on the mount and camera used.)
*The spatial frequency indicates the variation on the image plane before distortion correction is performed.

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

The Sigma 23 mm F1.4 DC DN | Contemporary has an easy-to-use angle of view equivalent to 35 mm in 35 mm 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 (340 g*, 76.9 mm length, 52 mm filter diameter). The high-precision machining technology of Sigma’s Aizu factory enables excellent optical performance and compactness. A quiet, high-speed stepping motor ensures fast and accurate autofocus.

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,” where the focus shifts by a fixed amount according to the rotation angle of the focus ring.

*Only for compatible L-Mount bodies.
Expands the 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 that combine superior resolution with compactness and light weight. Mix and match to build a portable system without sacrificing image quality.

A prime lens like a longtime friend

The wide-angle lens ideal for APS-C mirrorless cameras joins the Contemporary line. High optical performance, F1.4 brightness, and compact enough to carry around every day.

With an easy-to-use angle of view of 35mm*, high optical performance, the brightness of a large 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 demonstrates its descriptive power in a wide range of applications, including landscapes, portraits, and tabletop photography. In order to take advantage of the high mobility of mirrorless cameras, compactness of the lens body was also pursued. The Sigma’s 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.
