7D and 5D2 low ISO banding pretty much the same

But why people said 7D doesn't have Low Iso Banding problem like 5D2 ????????

Did someone really state this? Strange.

Anyway, they are equal , except the 5D2 does this mostly horizontally, the 7D vertically.

I have raw files from about 20 copies of the 7D, but only two of them don't exhibit the vertical banding with the 8-column periodicity. One of these are suitable for a direct comparison.

Disclaimer: this is ONE copy of the 7D. The periodic banding overrides this kind of "banding" in the other images; who knows how they would look like if that banding were not present?

Following are captures from ISO 100 7D and 5D2 images; the green spots in the first pair, and the red vas. the blue in the second pair are at the same average intensity level, -10.5 EV respectively -10.9 EV, i.e. in the mid/at the end of the 11th stop of the DR; that's where the 5D2 becomes ugly.
