Ah, this is one interesting comparison among the Canon 5D Mark II, the Canon 5D Mark III and the Nikon D800 with high ISO. The only light in the room besides the candle was some ambient light from streetlights outside. The f-stop was kept consistent throughout. The Canon footage was converted to ProRes HQ using 5DtoRGB, with the Mark II set to 601 color matrix and the Mark III set to 709. You’ll notice that around ISO 6400, the Nikon D800 is about to give out. The footage looks so grainy, I’m not sure if it’s usable in real life. The Mark III is still killing it at ISO 12,800, still very much usable at 25,600. Two things I do pick up: the model seems happier when she was shot with the Nikon D800; and why the heck does she blink every half a second?
