K20D banding, should I get it fixed?

I'm noticing quite subtle vertical banding with a good proportion of my images. Always present with DRange on, regardless of iso/raw/jpeg, and most obvious in intermediate shades and skin tones. Problem less obvious with DRange off, but still visible in some circumstances.

Am I pixel peeping too much, or do I have a real problem and should get it fixed?

Ah, I can faintly see it in the second picture. Are these 100% crops? I wouldn't fret over it too much, but what shooting conditions are you in? Temperature can wreak havoc on your sensor.

Yep, these are 100% crops, but I think jpg processing made them even more subtle.

So I shouldn't worry too much able it then. ^_^

Both of those shots are underexposed also, which will show banding. Proper exposure will eliminate it. By the way, I don't see it either!! LOL

If my K20 displayed similar results it would be boxed up and sent back while it was still on warranty.

I've seen Debbie's banding post, and admittedly this is very subtle and no where near as obvious. Some people say they can't see it, but to my eyes, the bands are definitely there, almost consistently if I look for it at the right places. But they are subtle and I don't notice them when viewing full screen on a 24" monitor, only see them if I zoom in closer. Pretty sure it won't be noticeable unless I get poster sized prints.

Has anyone else noticed these subtle bands in their shots? Is this "normal" in bad shots?

I'm just new to DSLR and still can't get correct exposure consistently, which worsens the problem. What I'm asking is, should I bother to send it back for repairs (might take weeks/months), or should I live with it knowing it's only a minor flaw and should improve with me taking better shots?

Any advice appreciated

If it bother you, you should send it back and ask for a replacement. I can see them on both pics, but I only view picture in 50%, or 75% for a few times.

Some suggest that a fast SD card will help and no more banding will show.

well, I also got a lot of pics with the more "subtle" banding, there were only a few with strong banding.
And I got underexposed pics with and without the subtle ones, you shuold get it replaced. Its nothing like it on the new k20d I have now.

I'm looking at them on a 20" Dell wide-screen (a month old and not calibrated), and I can see the banding in both pictures -- much more noticeable in the 2nd. Looks like rain falling straight down.
