2 HUGE problems with this test.
1) You only used one camera. You didn't do a side by side comparison with each shot against the D800? What gives?
2) You're actually out shooting something in the real world. You should be in a ridiculous situation, or shooting test charts in your mom's basement.

I kid, of course. After OD'ing on nothing but annoying fanboy peeing contest threads around here... it's becoming so that I can't even watch something like this without thinking "I wonder how the 5d2 or 7D or D800 woulda handled that wood grain at :54 - haha. A simple real-world, "hey check this out" is very refreshing!!!
