100-400mm f5-6.3 featured

In its product drop today (watch the replay of the livestream at the bottom of the page), Sigma announced several new lenses. The highlight? Its first ultra-telephoto lens for full-frame mirrorless cameras. Part of its “C” (Contemporary) series, it’s a 100-400mm DG DN series lens with an aperture range of f/5 to f/6.3.

This Sigma 100-400mm F5-6.3 lens, available July 10, combines super-high image quality with a compact frame, and it sports some other neat features such as an AFL button, a focus limiter switch, and a zoom lock switch. Read on for more:

This new ultra-telephoto lens is lightweight and compact (40 ounces and under 8” long) and features an impressive image quality comparable to Sigma’s standard zoom lenses, such as the 24-70mm F2.8 DG DN | Art. The smooth bokeh and compression effect made possible by an ultra-telephoto lens should be a boon for field photographers. It’s part of the DG DN series, designed for cameras with short flange back distances.

Some other features include a stepping motor system optimized for both phase detection AF and contrast AF, edge-to-edge high resolution, and powerful image stabilization capabilities. It’s compatible with high-speed autofocus and lens-based optical correction. It features a dust- and splash-proof bayonet, a 9-blade rounded diaphragm, and a zoom lock switch. The lens comes in two AF mounts: Leica’s L-mount and Sony’s E-mount. It comes supplied with the LH770-05 lens hood and the PT-31 protective cover.

What Else Is New?

Sigma also announced three other lenses and multiple accessories, including a teleconverter, two tripod sockets, and two USB docks (compatible mounts vary).

TC-1411/TC-2011 Teleconverters

Using the teleconverter with the 100-400mm F5-6.3 lens actually upgrades it to a “super telephoto” angle of view and a focal length of up to 800mm. It also doesn’t interfere with AF performance, so those willing to shell out a few hundred bucks on it will get nothing but benefit.

UD-11 USB Docks

Connecting the lens (L-mount only; sorry, Sony users!) to the new UD-11 USB dock allows adjustment of focus movement when operating the focus ring on Sigma’s Optimization Pro software. Specifically, this feature is useful for MF mode.
