Sigma 100-400mm F5-6.3 DG DN OS Contemporary Lens for Sony E

Entirely new design

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.

A full range of functionalities

This lens also features the *1 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, *2 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, *3 OS Switch which the user may switch between Mode 1 for general photography and Mode 2 for motor sports and other applications requiring panning.

Stepping motor and powerful image stabilization

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)
