Someone correct if I'm wrong, but I'm pretty sure they're using the Grasshopper3 camera, which retails for about $3k, and there are 14 of them in the pictured array. That's $42,000 just for the cameras. I know professional video shooting equipment is expensive, but that's more than double the price of a top of the line RED Epic-X camera that a professional 2d film crew might shoot on.
