Check the video playing @ 1:55 (2.45 - 2:49) & (2.44 - 2:45)
it has footage from "Art of flight" as well as
@ 2:10 both of which were filmed on canon dslrs. ( Art of flight had some red epic and other systems also but no Nikon. )
major research fail for Nikon or common?? I can see some other familiar footage but not sure of the source tho.
