I finally received my new GH2 camera and it is amazing.
In terms of image quality, it's on par with the GH1 Hack in normally lit situations. But in low-light situations, the GH2 shines. I shot the video below at 3200 ISO just to see how far I can push the GH2's sensor. I used my Pentax 25mm f/1.4 and my Rokkor 58mm f/1.4 lens.
Notice the lack of digital noise in the image. And that's at 3200 ISO. What? Although it doesn't shoot 4:2:2 like my GH1 hack, and it doesn't shoot pictures like my 1D Mark IV, I'm definitely considering getting rid of one of those cameras.
The video is of my childhood friend, Eddie, who asked me to shoot him eating a pig nose. It disgusts, nauseates and disturbs all in a matter of minutes. It's the first time I shot something that keeps making me sick with every viewing.
Anyway, enjoy and watch at your own risk. If you vomit, you have only yourself to blame.
