Seriously, the GH2 is very much a Honda Civic; it can be the most ordinary / mundane car around or it can be tricked out to beat Lamborghini's. The GH2 is a true test of skill for cinematographers, in that it's not the easiest camera to use and certainly won't hold your hand when you get into trouble. But if you're patient and know what you're doing... it's going to seriously surprise you. I'm with Shian, when I say in all honesty... there is simply no way I'd ever shoot anything besides the GH2 at 20k or under, apart from a Scarlet or the BMC... period.
If your goal is specifically to get the most "cinematic" image possible, rather than seeking a camera that'll make your job easier... the GH2 is simply unbeatable. It far surpasses any of the Sony cameras like the FS100 or even the F3, or the C300 in terms of that genuine film-like aesthetic. It's certainly not anywhere near their capability in terms of DR, low light and all the onboard options for monitoring and audio etc.. But for pure IQ, it really does look the best in my opinion.
