Update: B&H has changed the information on their website regarding the scheduled Sigma preorders. It appears the only lens that will be open for preorders tonight is the Sigma 135mm f/1.8 DG HSM Art lens.
Preorders will go live tonight at midnight Eastern Time for Sigma's latest batch of Global Vision lenses.
We expect demand to be very high for all of the new Sigma lenses. Preorder early to ensure your shipment arrives as soon as possible. And when preordering, please remember to use our links to support this site!
We'll make another post at midnight tonight when preorders become available.
