The price of the 10mm f/2.8 FF AF lens has been leaked through google shop. This contains a link to this “private” Venus Optics URL: https://www.venuslens.net/product/private-laowa-10mm-f-2-8-ff-zero-d/ref/5/ . The lens is coming to your home on Jan 31.
I guess official preorders will open any time soon!
