A video Test done by Joe Marine, Nikon D800 sensor captures more light compared to 5D Mark II and 5D Mark III under low or High ISO settings, but both 5D Mark II and 5D Mark III have less noise at high ISO with bit flat details due to in-camera noise reduction filters.
Nikon D800 performance is excellent up to ISO 1600 the sensor captures more details compared to its competitors
At High ISO Both 5D mark III and II have less noise,
Personally I will prefer 5D mark III or II for video, Which camera do you prefer? – Nikon OR Canon – Share your thoughts with us

Hi I own nikon D800 and very happy about it as it does what it ment for. Good for stills and it gives the shooter room for cropping. Tumbs up. Also I feel nobody will shoot at crazy hi ISO. Cheers
