Mmm, perforation. 1000fps may've impressed with the previous model, but a whopping 2800fps at 1080p? Wow. If you crank the resolution all the way down to VGA, you can even shoot in 6300fps.
Flex is the latest model from Vision Research, whose professional Phantom line of camcorders tends to the more expensive side of the market but the specs are pretty astounding. This particular one has a 4K 2560 X 1600 CMOS sensor with 12-bit colour depth. As mentioned before, when shooting 1080p it films in 2800fps, but you can get 1560 when pushing the resolution even further. [Phantom Flex via OhGizmo]
