NAB 2012 is currently underway in Vegas, and a number of companies have announced new products, all of which seem ludicrously expensive to those of us on the still photography side of things, but are more or less standard in the world of motion.
RED cameras has announced a large number of new products, including Canon, Leica, and rumored Nikon adapters. But the big news out of their camp is the new Dragon sensor. This upgrade for EPIC and Scarlet adds 6K video support (6,000 x 4,000), promises 15+ stops of dynamic range, and 120fps at 5k size. It's expected to fetch $6000 on EPIC and an unknown amount on Scarlet.
