An amazing video you have to watch! This is Tommy-T the Cheetah running at top speed and is filmed at 1200fps with a phantom camera speeding along side by the National Geographic team. There's a behind-the-scenes video as well which really puts it all into perspective – oh, and there are at least 4 Canon EOS-1D X cameras included in the shoot – tho we don't get to see the output from those DSLRs.
