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.

I've seen this problem when the GH-2 first came out on a Vimeo video with someone playing with fire (twirling and spinning etc). That video initially scared me away from the camera but I have not seen it in other videos since (not even in my videos).

Thanks, Ian. Do you remember the link/how did that person resolve the issue?

No one has an answer for this problem?

I remember the video Ian is mentioning, but I can't find it. It was about some Hawaiian fire show or something like that.

This issue was discussed at length when the GH2 came out. For example, here: http://www.dvxuser.com/V6/showthread.php?230484-GH2-Blue-horizontal-banding&highlight=GH2+banding+fire

You don't say what kind of lens you were using. Was it a m43 or something with an adapter?

I filmed and stopped the recording, tried again, adjusted, stopped recording as it kept occurring. So, I have a few shorts with it which I can link to you guys in a bit. It was over Thanksgiving break at my friend's house, so I'd have to start a fire in my backyard to recreate it (which I'll probably do also).

20mm pancake lens, no adapter.

That happens to me when I'm very underexposed. Try opening iris or increasing gain.
