What about Lens options ? I have the 7d with the L-Glass the best you can have. How will the GH2 quality compare with the Lumix Glass vs the L-Glass ? Also will GH2 adapters be able to Autofocus or use Aperture ? What are the negatives of using an adapter. I need to make some crucial decisions. I like the GH2 bc its touchscreen and have AF during video. Also the codec thing is tricky too. Please help me.
