When the RED Scarlet was introduced as a concept back in the olden days of 2008, it was a much different animal. It was supposed to be a video camera with a 2/3-inch sensor that shot 3K (which falls between 1080p and 4K on the resolution scale) footage for about $3,000. But yesterday, in direct conflict with Canon's big EOS Cinema C300 announcement, they went official with a $10,000 camera packed with some serious movie-making horsepower.
