What's amazing to me is how much one camera can look excellent in one scenario and then look like total crap in another. I was amazed how good the 5dmkII and the 7d looked with the girl and flower scene...yet the GH1 did not look good at all...but then they did the green screen test and the 5dmkII and the 7d look like crap in the reproduction of the jean colors, yet the GH1 outshines them.
I've noticed this before in my own productions. I own al three cameras and now when I go scouting for locations or do a pre-pro, I take the cameras and see which one would fare better with the conditions at hand...
That sounds intelligent. The right tool for the right situation.
