According to RED, the new camera packs a completely new sensor architecture with an updated pixel design that will improve image detail and color in the shadows.
While the size will remain Super 35 and have the same 19.9MP layout, thanks to an upgrade to the processing power, the new global shutter sensor will output 6K at 80 fps and 4K at 120 fps, a nice bump from its smaller sibling.
