Unlike still cameras most professional video cameras use three color sensors and a beam-splitter arrangement. Now there is great excitement with cameras like the Red One who use a larger, probably APS-C chip with a Bayer pattern. Both will give shallower DOF than the typical 2/3 inch sensor size of professional video cams. The other advantage that cameras like the Red have is that they can output a raw video stream. Like in still photos this leads to an image that is able to be manipulated to a greater degree in post production without gaining noise. The new Panasonic camera only records a highly compressed video stream on SD cards rather than a much more lightly compressed stream that a high-end 2/3 inch camera like their Varicam records. The Varicam, of course, cost 5x as much as the new 4/3 camera will and thus serves a different market. We'll see how the new camera compares to the similarly-priced 1/2 and 1/3 inch video cameras on the market. Some of those do pretty well.
