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

1.SIGMA's 5th DG DN lens with an exclusive new design for full-frame mirrorless cameras

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 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.

3. A full range of functionalities that realizes 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 four 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 AFL button to which the user may assign select functions on the camera side, and the focus limiter switch that allows optimizing the AF range according to the purpose of shooting.

Meanwhile, 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.

Furthermore, 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 selections 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 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.
