This morning, Sigma officially unveiled its much-anticipated 105mm f/2.8 DG DN Macro lens for full-frame mirrorless cameras. This is Sigma’s first Art-series Macro lens for a mirrorless system, and it’s been optically re-designed from the ground up to deliver “exceptional sharpness and pleasing bokeh.”

Optically, the new mid-telephoto macro lens is made up of 17 elements in 12 groups, including one Special Low Dispersion (SLD) element to minimize aberration. The construction allows the lens to achieve a 1:1 reproduction ratio at a working distance of 5.5 inches (14cm)—and if you slap a 1.4x or 2x teleconverter on the lens, you can increase that reproduction ratio all the way to 1.4:1 and 2:1, respectively.

Moving on to the lens itself, the Sigma 105mm f/2.8 DG DN Macro is dust and splash proof, with a brass bayonet mount and a 9-blade rounded aperture. On the barrel, you’ll find a focus limiter switch with three settings (Macro, Portrait, or Full-Range), an Aperture Lock Switch, and the ability to choose between a “clicked” or “de-clicked” aperture action.

Finally, the autofocus on the lens is run by Sigma’s Hypersonic Motor, and promises to deliver “smooth, quiet, confident autofocus in both close-up and portrait-distance settings,” even if you don’t take advantage of the aforementioned focus limiter switch.

Sigma is making some bold claims about the performance of this lens, and given its track record with the ART series, we sincerely hope that it delivers. Here’s a hands-on first look from our friends at Adorama, who set out to find out for themselves:

The Sigma 105mm f/2.8 DG DN Macro lens is available in Sony E-Mount and Sigma/Panasonic/Leica L-Mount for $800, and should begin shipping in “late October.” To learn more or if you want to pre-order your own, click here.
