B&H is now shipping the Sigma 85mm f/1.4 DG HSM Art Lens to preorder customers. The Nikon mount version is currently in stock with more Canon mount inventory expected soon.
B&H has a shipment of Canon EOS-1D X DSLRs in its warehouse and is in the early stages of shipping preorders. Because of the long hiatus, preorders may take a few days to ship.
Note that the free 64GB CFast 2.0 memory card and reader deal ($300.00 value) was scheduled to end once the camera came into stock. B&H has yet to change the camera's stock status, so there's still time to take advantage of the great bundle deal.
Update: Adorama has the 1D X II Premium Kit (with free memory card) listed as in stock.
Amazon is now shipping the the following lenses:
FYI: B&H has the Canon EF 35mm f/1.4L II USM in stock and has already begun shipping lenses to preorder customers.
B&H has just started shipping the long-anticipated Sigma 24mm f/1.4 DG HSM Art Lens for Canon.
I don't know if B&H has enough stock to meet the preorder demand, but now would be a good time to submit your order if you haven't already.
