Hi guys,
I used my GH2 last night and was disappointed to come across a terrible banding issue. The following photo exhibits the problem (1/50, ~ISO640):

If it wasn't obvious, the setting is a bonfire. What could this be caused by? I even changed the shutter speed a bit, remembering what I'd read about the issue and it was still there. I've never seen this particularly glaring problem posted up, however, because it seemed to be worse when I lowered the ISO.
