Sigma 100-400mm f/5-6.3 DG DN OS Contemporary for Fujifilm X Mount APSC

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 F5-6.3 DG DN OS | Contemporary makes shooting with the video or eye-tracking AF very smooth.
SIGMA’s 5th DG DN lens is a long-awaited ultra-telephoto zoom lens. This lens will expand the possibilities of mirrorless camera photography even further.

Product names: Abbreviations DG and DN indicate that the lens is suitable for full-frame cameras and is designed exclusively for mirrorless (short flange back distance) cameras, respectively.

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.

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.

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

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.
