Lens manufacturer Sigma is expected to announce three upcoming mirrorless lenses in their Contemporary range in the coming weeks. All three of the lenses are designated “DN”, which means they’re designed for mirrorless, but only two of them are also designated “DG”, denoting full-frame. The third is a “DC” lens destined for APS-C sensors.
The full-frame lenses are a wide angle 17mm f/4 DG DN Contemporary and a fairly standard 50mm f/2 DG DN Contemporary. While specs have only been leaked relating to the Sony E Mount version, I think it’s a safe bet to say they’ll be coming on L mount, too. The third is a 23mm f/1.4 DC DN Contemporary, offering a similar field of view go 35mm on full frame for Sony L, Leica L and Fuji X mount cameras.

There’s no word yet on when we’ll see the new lenses being announced, although they’re expected to come in “the next few weeks”. More lower-budget full-frame lens options are always a good thing, and with the ISO performance on modern mirrorless cameras, you can afford to stop down a little from the f/1.4 and f/1.2 ultra-bright lenses and still get a decent shot. Sure, your depth of field might not be able to always get as shallow, but does it always need to be paper thin?
As for the 23mm APS-C lens, well, that one does have a nice bright f/1.4 aperture. This will add to Sigma’s DC DN Contemporary lineup quite nicely. Now that the company has finally jumped on X Mount, I can potentially see their APS-C lens lineup in the future expanding quite steadily. Interestingly, though, this version isn’t being rumoured for X mount – a recent move for Sigma that’s been cause for a lot of celebration amongst APS-C Nikon shooters.
Maybe this one will eventually come to Z mount once it’s been made official. Given that Nikon’s being pretty tight with handing out licenses, though, we may not.
