Banding on 5d2 but not on another.

I have 2 5d2s one has just been back from Canon where they did a "hard Reset" , now I can see all these "cuadrants" on all my files shot at iso 100 f11-16. On a zeiss 18mm.

Has anyone seen this before and know how to remedy as I am working away from "Home" - Can it be the software on teh machine , but in taht case why not on my other setup 5d2+24-70mm?

If anyone has experienced this and shed some light please ket me know as im really getting nervous.......

27 july - 2 Month later: A very important update to 5d2 owners. I have just received a new in box 5d2 from Canon. They acknowledged the problem.

it looks like sharpening artifacts, but these are "RAw" files with nothing applied.

do you know what they have done with it.?

I see it too. Very likely it's a hardware problem, might wanna send it to Canon.

It's funny that all the 5D MK II owners stay away from this thread. Denial?

LOL

You should send it back to Canon.

I'm not sure what there is to deny, the OP has one camera that does this, and one that doesn't--that makes it pretty apparent that not all 5D's do this...

Neither of my 5D's do this, but I've seen other examples of it. I would send it back to Canon.

I think there was another thread on POTN about this calling it a "mouse maze".

My 5D doesn't do that though - definitely not, I'd have noticed.

This is not a typical 5D2 problem. Perhaps you are confusing this problem with the 5D2 shadow banding issue.

What the OP is showing here is the result of different resistances in odd and even line selectors and/or different amplifications for odd and even lines. This creates non-existent "detail" in the green channel, since the green pixels are in all rows and columns.

I recall a post some time ago where someone had a 7D and saw similar patterns at 100% viewing. And this individual eventually isolated the cause of the banding as having HTP set to on.

As you noted that you just got your camera back from Canon, and AFAIK, HTP is on by default. I guess it doesn't hurt to give it a shot and see if HTP has been turned back on, and if so, turn it off and take some new test photos?

I know it's a long shot but hey, you got nothing to lose.

You can't take me seriously Tim. I've shot quite a few 5D IIs and while I feel it's not the camera I wished for, I continue to use my 1Ds MK III.

I'm not confusing the problem with the noise banding issue at all. I'm totally aware of that. I just can't remember where I read about the banding Zinco is talking about.
