Chris.
A weather sealed ultra wide, is that too much to ask?

Thank you so much, Chris! I've followed you advise to add some noise, or not to do any PP at all, and exported in JPEG format. I'm terribly sorry to tell you that the bands stayed on the image(s). I'll have to say that I have to surrender now.

It was a misty afternoon, I guess it might have something to do with the sunlight in the late afternoon and the rather dense mist in the mountains. I've never met this case before with my K-5 and Kx. Maybe I wasn't in such similar condition either. I was using DA L 55-300 (this came with Kx) for these shots.

Don't give up! It is a nice shot, and if you work from a 16-bit TIF you can probably find a good work around. My solution when all else fails in this kind of situation is to use brush - set at large radius, at a "soft" setting and very high transparency spread along the banding area; it might take more than a single stroke. This will tend to soften or eliminate the pixelization without further damage. Not sure the name of the brush for your particular software, but in Picture Window Pro "smudge" is most effective.
