I recently purchased a GH2 and have hacked it with Moon T7. It is amazing, thanks so much for this patch!

While testing out an interview sort of setup, I kept getting random bands of noise in the underexposed areas of the frame. This only happens in EX Tele mode and it is extremely distracting. Every frame seems to generate a new pattern of noise so the bands are quickly jumping around. I uploaded two consecutive frame grabs to show this. While my face is clear of the bands, the slightly underexposed space to the left is badly banding.

Any ideas why this is occurring? Maybe I am overlooking something.

Focus is set to manual, nostalgic with all at -2 except noise reduction which is at -1. White balance around 5000K. ISO is only at 200.

Thanks for any hep!
