Wow. This camera is amazing. Even though this camera is way out of my price range I wanted to bring up something.
This camera does:
17 915 904(pixels) x 14(fps) = 250 822 656 (pixels per second)
On the other hand, 4k digital cinema is:
7 020 544(pixels) x 30(fps)= 210 616 320 (pixels per second)
Of course, when the 1dx shoots 14 fps these pixels are compressed into JPEG format. Also, the 1dx cannot shoot at 14 fps per second for more than a few seconds, but I think it is interesting that it might be possible to shoot compressed 4k clips with this fantastic new camera.
