Im borrowing a friend's 5d mkii and noticed that at 100% zoom you can definitely see vertical lines.
Ive called the local repair places and canon and inquired about it and they say that it will either need a new sensor which would cost around $800-$1200 or a couple hundred dollars to fix.
Is it worth repairing this? The vertical lines are very faint and is only visible at 100% zoom. For those who had this issue before, did you get it fixed? or just live with it?
Ived own several 5d mkii and this is the only one that has it.
It looks like you posted a 100% crop of the first surfer (good). If I look at it at 200% I can see the vertical lines but they seem to be compression artifacts from the 8x8 JPEG blocks, due to the low level of quality in the JPEG saving.
When you see the vertical lines, are you viewing the Raw in your converter before saving the converted image or are you looking at a JPEG you saved and have opened to look at? Try saving at high quality (11 out of 12, or 12 out of 12 in Photoshop, or 95 % to 100% quality index).
I was just comparing some files from 5dmkii A ( vetical lines ) and 5d mkii B (no lines)
Same processing, same viewing and all edited, and exported with LR3
I guess my next question is. Would this kind of vertical banding considered terrible to the point that this camera needs to be repaired or save the money and stop pixel peeping?
No repair necessary. It seems that the user processing (conversion) or post-processing is in error. They are definitely not given the same treatment (see the difference in sharpening), and the compression at level 6 is crushing the images.
I put them side by side enlarged at 400% (with nearest neighbour to preserve pixels):
You can clearly see how there is a JPEG compression pattern and sharpening halo in the first one and not the second one. Something different is happening in the workflow.

I took photo 2 and synced it with the same settings of photo via lr3
If I zoom all they way in with both photos. I can still see very faint vertical lines.
At this point I feel that Im over analysis both cameras. Ive never had 2 of the same camera except the 5d mkii. Is it possible that these cameras are rendering different artifacts? if so It looks like I might have to pick one and just move on.
I do not use photoshop much and if I have to result in using it other than LR3 then that adds to my workflow which is not I am looking for.
again this is all pixel peeping. I think the next question would is how this affect the images in final presentation.
that looks pretty bad, looks like 7D banding only super bad even for that
unless that was under by 4 stops and lifted i think something has gone wrong or he got one of the rare 5D2 that were known to have come mangled straight from Canon new in box since some were damaged like that out of box and had strong vertical gain banding and mazing artifacts

I had exactly the same "cross type" banding on my 5D2 after I had sent it in for another issue. Canon Service did something to it, so I returned to be fixed. This was in 2010.
They fixed the issue and I haven't had a problem since.
On the service notes, they said "Adjusted the CMOS." Also, "...upon close inspection the exact cause could not be identified but it was found that noise appeared in the image. Electrical adjustments were carried out on the cmos assembly"
