I know GH1 vs 7D threads are worthless, but this isn't really one. I only have one specific thing I'm looking for: which camera, if there is one, is less likely to screw up highly detailed scenes out in a forest? Forests are the easiest things to find here, so those are going to be most of my locations. I can only soften the background so much. And yes, I know none of them are ideal for that condition.
