SIGMA is pleased to announce the launch schedule of the SIGMA 23mm F1.4 DC DN | Contemporary and the 100-400mm F5-6.3 DG DN OS | Contemporary in FUJIFILM X Mount. 

The SIGMA 23mm F1.4 DC DN | Contemporary, a large-aperture wide-angle lens designed exclusively for APS-C mirrorless cameras, will now be available for the Fujifilm X Mount.

A control algorithm including AF drive and communication speed optimization has been developed specifically for X Mount interchangeable lenses. In addition to realizing high-speed

AF, the lens also supports AF-C (Continuous AF) and in-camera aberration correction. The mount is rubber-sealed to cater for use in a variety of environments

１．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.

２．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 335g*, length of 79.2mm*, 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.

３．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. 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 image quality.

The SIGMA 100-400mm F5-6.3 DG DN OS | Contemporary, which was created in 2020 as the "Handy Tele Master", the DG DN version of the ultra-telephoto zoom dedicated for full-frame mirrorless cameras, will now be added for the Fujifilm X Mount.

With the mirrorless large-aperture F1.4 APS-C size single focal length (16mm, 23mm, 30mm, 56mm) , F2.8 zoom (18-50mm), and the addition of this super-telephoto zoom lens, SIGMA's X Mount lens lineup has expanded to six lenses. The new lineup covers a wide range of applications, from wide-angle to ultra-telephoto.

A control algorithm including AF drive and communication speed optimization has been developed specifically for X Mount interchangeable lenses. In addition to realizing high-speed AF, the lens also supports AF-C (Continuous AF) and in-camera aberration correction. The mount is rubber-sealed to cater for use in a variety of environments. The switches have also been optimized for X Mount. The "AF Function Setting Switch" allows the user to select a function while the AF Function Button is pressed on the lens side. 

１．Compact ultra-telephoto zoom equivalent to 600mm in 35mm format

The SIGMA 100-400mm F5-6.3 DG DN OS | Contemporary for X Mount, the sixth lens to be converted to X Mount, is a ultra-telephoto zoom lens covering an angle of view equivalent to 150-600mm in 35mm format. Despite covering the 600mm equivalent ultra-telephoto range, the lens has a compact design with an length of 199.5mm, a maximum diameter of 86mm, and a weight of 1,135g. It enables ultra-telephoto photography utilizing the compact Fujifilm X Mount system. The SIGMA 100-400mm F5-6.3 DG DN OS | Contemporary, designed for full-frame mirrorless cameras, can be used with an APS-C format X Mount body to deliver extremely high descriptive performance right up to the extreme periphery.

２．Uncompromising image quality

The lens construction of the SIGMA 100-400mm F5-6.3 DG DN OS | Contemporary comprises 16 groups and 22 elements, with one FLD and four SLDs used for the effective correction of aberrations and distortions. Built on the latest optical design technology and optimized for mirrorless systems, the lens ensures the same high-resolution image quality all the way to the edges. In addition, it constantly achieves high levels of optical performance and makes the most of its capabilities as a zoom lens in any condition, at every focal length from wide to telephoto, and from close-up shots to telephoto photography.

３．A full range of functionalities that enables smooth and easy ultra-telephoto shooting

In addition to a high-speed and smooth AF enabled by the stepping motor optimized to the latest algorithm, the SIGMA 100-400mm F5-6.3 DG DN OS | Contemporary incorporates powerful image stabilization (OS) of five steps* built into the lens. When combined with a camera body with image stabilization built in, the lens corrects for pitch and yaw axis rotations, providing even more powerful image stabilization. It also features the AF function setting switch to which the user may select AF lock/AF activation, and the focus limiter switch that allows optimizing the AF range according to the purpose of shooting, Zoom lock switch that fixes the zoom ring at the widest end, preventing it from rotating and causing the lens barrel to extend under its own weight during transportation, OS Switch which the user may switch between Mode 1 for general photography and Mode 2 for motor sports and other applications requiring panning. In addition, the SIGMA 100-400mm F5-6.3 DG DN OS | Contemporary supports straight zoom, which allows photographers to zoom in and out by adjusting the hood, enabling intuitive and quick view angle adjustments. It features a “Dual action zoom” which supports both straight zoom and ring zoom.

４．Lightweight & Compact lens body

SIGMA designed a light and durable ultra-telephoto zoom lens addition to its Contemporary line. The SIGMA 100-400mm F5-6.3 DG DN OS | Contemporary packs functionalities required for angles of view corresponding to focal lengths of 100-400mm in a compact, lightweight body. It is not merely about weight reduction, but the lens is durable, with careful selection to utilize the right materials in the right place. For instance, magnesium alloy is used for the part where a tripod socket is attached, which needs to be very strong. To allow for a pairing with camera bodies of different sizes, a tripod socket, TS-111 kit (sold separately) is available. As this helps reduce any strain on the camera body, photographers can shoot long hours without worrying about it. The tripod socket comes with a strap which also helps reduce strain on the mount when carrying the lens around or during transportation.
