There have been rumours about Sigma releasing a 50mm f/1.4 DG DN Art series lens for mirrorless cameras for a little while. A couple of weeks ago, we saw some of the specs leak and now, thanks to Sony Alpha Rumors, we have our first photo of the lens showing what it’ll actually look like. It’s a significant design change from the Sigma 50mm f/1.4 DG HSM Art for DSLRs, showing quite a different exterior. The interior is also different, with a new optical formula with more elements in more groups. Sigma has also announced a Sigma Stage Online event for February 7th, with a description talking about discovering new products. So an announcement for something is definitely imminent. Could it be the new 50mm f/1.4 DG DN Art lens?

Some specs for the upcoming lens leaked a couple of weeks ago and look a little something like this…

Lens construction: 14 elements in 11 groupsShortest shooting distance: 45cmMaximum magnification: 1:6.8Number of aperture blades: 11 (circular aperture)Filter diameter: 72mmSize: 78.2 x 109.5mm (L mount)Weight: 670gLens hood: LH782-02Lens cap: LCF-72 III

As well as L mount mentioned above, it’s also expected to come in Sony E mount. So far, there’s been no word or updated rumours on when we might see Sigma jump into Nikon Z mount. Maybe it’ll be this or maybe it won’t. Until the event, we won’t know for sure. The Sigma Stage Online Event is scheduled for February 7th at 9pm JST – that’s Japan time. That means noon in the UK, and 7am Eastern or 4am Pacific for those in the USA.

I doubt we’ll get a full-frame Foveon announcement during this presentation. Hopefully, though, we might at least see an update on the current status!
