Even though Nikon was the first DSLR out of the gate with 24p video, it was Canon that really made a splash with the Mark II not long after. Nikon tried to get back some of that market with the D800 and D4 aimed at video shooters, and now they are pushing even harder with the new D810, which adds 1080p 60fps, higher ISO capabilities, and simultaneous recording to both internal cards and an external recorder. While there is a big push to add 4K recording to these kinds of cameras, neither the newer D4s nor the new D810 have it. – Joe Marine, No Film School http://ift.tt/TnnZtr
