but I can comment that the dude hosting the show scares me.
That was my very first thought when I watched it, too

That guy fell off the ugly tree and hit every branch on the way down. And then a badger ripped up his face.
Seriously, though, that was poorly thought out (or maybe it wasn't, read on...), unscientific and done purely for ratings and advertising (how much did Nikon pay for the D700 to win?).
The biggest flaw is obviously ISO 400. Why? (yes, that's rhetorical, Nikon probably paid them to do that).
Everyone knows that ISO 400 is about the threshold for acceptable quality and grain in film. But even on the D40, ISO 400 looks great. No doubt, it looks phenomenal on the D700. OK, we know that ISO 400 is better on a digital than on film. Get over it, move on, you don't need to test that.
And who uses ISO 400 in a studio where they have all the lighting equipment in the world at their disposal?
Take this video with a mountain of sodium chloride.
