the Phantom v1610 can film up to 1,000,00 frames per second.
granted, to reach that speed, the resolution is extremely low, at only 128x16, and the memory can only hold 4.19 seconds of footage.
however, at 1280x800, it can shoot up to 16,000 frames per second, and 18,000 at 720p.
I don't know who would ever need to film anything at a million frames per second, especially at that tiny resolution, but the idea of it is mind-blowing.
