Patent: The Sigma 24-70 f/2.8 OS ART is Coming

Sigma have patented a new 24-70 f/2.8 design which will surely be the OS ART lens that many people are waiting for. Look for this lens at the end of 2016, or the first quarter of 2017.

I wouldn’t be at all surprised to see this lens launch alongside the inevitable, and already-patented 70-200 f/2.8 SPORT.
