According to an article on the dpreview site, OIympus have acknowledged that there is a potential problem with banding at high ISOs when using the OM-D/Panasonic 20mm pancake lens combination. They are working on a fix. Has anyone here experienced any problems?

Interesting.
This seems to be a lens-specific issue since I took a lot of shots last week at 1600 - 3200 ASA with both the Pan-Leica 25 and the 40-150 m.Zuiko in indoors natural light at a wedding and I can't see any problems like those shown in the thread (although some of those posts are now getting above my technical and visual competence ;-] ).

I've heard of 'banding' but have never seen it on my E500, E3 or E5. Mind you, I don't inspect my prints close enough to get grease spots from my nose on them. I also suspect that the too high contrast of an uncalibrated LCD monitor may show such issues. (From what I've seen of too dark images on this site, lots of people are using uncalibrated, and hence too bright and contrasty, LCD monitors!)

Banding on the E-3 at ISO 1600 or 3200 was definitely a problem if there were large areas of darkness in the frame. It was not such a problem with bright scenes.

I have not seen banding on the E-M5 unless I haver applied outlandish post processing adjustments!
