I have had this banding on some 20D images. Usually it is more noticeable on High iso images that were underexposed and then 'corrected' later.

I just went back to look at the image in raw and it's still there.?

This looks like what happens when I apply to much sharpening. What are the cameras sharpening set to and how much sharpening did you do after?

It's only sharpened in camera at 5, but nothing after that.

I don't know about that camera, but 5 seems like a lot. Try the same shot with no in camera sharpening, or a least reduce it significantly.

I saw this exact same thing in a photo last night. I did a sharpen 3 times. On the 3rd time it was very visible. I restarted and on the second time it was visible if you look real close. So I still think this is sharpening. Maybe I'm just biased because I saw this last night.
