I've never seen this "shadow banding" stuff, or at least I don't
recognize what you mean. Can you provide an example?
You'r very lucky to have never seen it. Google has heard of it.
You'll find plenty of references there. Frank Theriault pointed it
out in one of his pictures a year or two back.
The K100D and Super exhibit banding noise very badly from ISO 1600 and
up. This type of noise, which is *very* hard to cleanup, is one of the
main reasons I got a K20D (which is completely free of it no matter how
noisy the image gets). I assume the same banding noise appears in *istD
bodies as they have the same sensor.
Here's a photograph with some serious shadow banding:

Here's my repair:

My hat's off to you, Anthony! You did a really remarkable cleanup on
that image. A great shot too.
