Sigma 100-400mm f/5-6.3 DG DN OS Contemporary Lens for Leica L

Introducing a long-awaited ultra-telephoto zoom lens designed exclusively for full-frame mirrorless cameras

With the levels of optical performance and functionalities essential for full-fledged shooting packed into a lightweight and compact body, which is a key in field photography, the SIGMA 100-400mm F5-6.3 DG DN OS Contemporary is an ultra-telephoto zoom lens that invites you to take it with you on casual outings.

The state-of-art optical design technology ensures edge-to-edge high-resolution and high-contrast image quality throughout its entire focal range. This new lens achieves high image quality which rivals that of standard zoom lenses such as the SIGMA 24-70mm F2.8 DG DN Art, ensuring a perfect match with these lenses while shooting.

The level of bokeh and compression effect only achieved by an ultra-telephoto lens provides a fresh perspective to ordinary everyday scenes. This combination of ultra-telephoto images with the excellent mobility of the SIGMA 100-400mm F5-6.3 DG DN OS Contemporary will open up new ways for you to enjoy ultra-telephoto photography, as well as its possibilities, from everyday snapshots to field photography and everything in between.

Whether you are currently considering trying a telephoto lens or already are a telephoto lens connoisseur, the SIGMA 100-400mm F5-6.3 DG DN OS Contemporary is a "light and enjoyable ultra-telephoto zoom lens" that will provide a great value and a variety of styles to your shooting experience.

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 new 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.

Furthermore, when paired with SIGMA TELE CONVERTER TC-1411/TC-2011 (sold separately / for L-Mount only), which was newly and exclusively developed for the use with mirrorless cameras, the SIGMA 100-400mm F5-6.3 DG DN OS Contemporary gives photographers a "super-telephoto" angle of view with a focal length of up to 800mm while they enjoy the benefit of the compact system. Plus, AF is effective even with the teleconverter attached.

A full range of functionalities that enables smooth & easy ultra-telephoto shooting

In addition to a high-speed and smooth AF enabled by the stepping motor optimised to the latest algorithm, the SIGMA 100-400mm F5-6.3 DG DN OS | Contemporary incorporates powerful image stabilisation (OS) of four steps* built into the lens. When combined with a camera body with image stabilisation built-in, the lens corrects for pitch and yaw axis rotations, providing even more powerful image stabilisation. 

* Based on CIPA guidelines (Measured in 400mm with a 35mm full-size image sensor)

It also features the 1AFL button to which the user may assign select functions on the camera side, and the focus limiter switch that allows optimising the AF range according to the purpose of shooting, 2Zoom 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, 3OS Switch which the user may switch between Mode 1 for general photography and Mode 2 for motorsports and other applications requiring panning.

Sigma USB Dock UD-11

By connecting the lens to SIGMA USB DOCK (sold separately / for L-Mount only), which was newly developed exclusively for the use with mirrorless cameras, users can adjust the amount of focus movement when operating the focus ring on exclusive SIGMA Optimization Pro software, which allows users to adjust focus in their preferred timing in MF mode.

Dual-action zoom

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.

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 selections to utilise 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 paring with camera bodies of different sizes, a tripod socket (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.

Other Features

• Mount with dust- and splash-proof structure: The mount features a special sealing to make the lens an excellent choice in a wide variety of conditions.
• High-precision, rugged brass bayonet mount: The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
• Rounded diaphragm: The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
• Designed to minimise flare and ghosting: From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions.
• Compatible with Lens Aberration Correction: Matching 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.
