Sigma patented a 12mm f/1.4 MFT lens design

Sigma patented a new 12mm f/1.4 lens design for the Micro Four Thirds system. As usual we don’t know if such a lens will ever be produced for real. Also note that this design is very different from the recent Panasonic-Leica 12mm f/1.4 lens.

So I wonder what’s in Sigma’s mind right now…will they really make it?
