Introducing a long-awaited ultra-telephoto zoom lens designed exclusively for full-frame mirrorless cameras. With remarkable 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 f/5-6.3 DG DN OS Contemporary Lens is an ultra-telephoto zoom lens that invites you to take it with you on casual outings. The optical design technology ensures edge-to-edge high-resolution and high-contrast image quality throughout its entire focal range. This lens achieves high image quality ensuring a perfect match with these lenses while shooting.

Designed Exclusively for Full-Frame Mirrorless Cameras

With the optics design specifically for a camera with a short flange back distance, the DG DN series of lenses achieves a supreme combination of optical performance and compactness that could not have been possible with lenses for single-lens reflex cameras. Thanks to the stepping motor system that is optimized for both phase detection AF and contrast AF, the Sigma 100-400mm f/5-6.3 makes shooting with the video or eye-tracking AF very smooth. This lens will expand the possibilities of mirrorless camera photography even further. 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 this contemporary lens 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.

Uncompromising Image Quality

The lens construction of the Sigma 100-400mm f/5-6.3 DG DN OS 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, this lens ensures 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.

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 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. Furthermore, this lens supports straight zoom, which allows photographers to zoom in and out by adjusting the hood, enabling intuitive and quick view angle adjustments. It also features a “Dual action zoom” which supports both straight zoom and ring zoom.

Lightweight and Compact Body

The Sigma 100-400mm f/5-6.3 DG DN OS Contemporary Lens 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.
