I have found this topic, I do not know if it solve the problem, my english is not perfect (really far...) and maybe I misunderstand. But I will give a try.
I got 7D only because I wanted to shoot in RAW (video) but the stripes are so heavy, so I really hope to find out a productive solution.
All the CANON camera that I have tryed suffer from vertical banding fixed pattern noise. So this problem is really old. But nobody talk about it. I wish to know if esod HD talked about it in the past 5D, 7D, Rebel Series, etc, etc... series. Nobody in every website I visited talked about it. and the most always said that the image quality from canon DSLR were oustanding. But in low light "vertical banding" is everywhere.
I cannot understand why anybody never talked hard about this problem. maybe I guess could be because Canon camera are the main tool of works of many people so they want so keep clean the "image" of theyr tools. I'm totally wrong and stupid talking about this I hope.
With ML i have noticed a lot of this lines on + EV setting used in a very dark scene with only a camp fire to light it, after this i started to notice lines, somethimes on 0 EV set
the lines disappear with setting of negatives values on EV accordingly with the ISO used (ML ISO).
