I think Bill did a good job of explaining the theory James, so I won't
repeat it. But I will suggest that you try a circular polarizer against a
linear polarizer, because it *may* have a less pronounced effect. I do not
recall ever seeing banding with a 17mm using a circular polarizer - but
maybe I either wasn't looking, or didn't have the scene framed so as to
include the banded area^. Best UK price I have found on circular polarizers
is at Denton Photo Optics - they advertise in AP.

^ Though I tend to have too much sky rather than too little - the reason for
having the 17mm.
NB "the reason for" not "the result of" ;-)

Subject: [OM] 24mm and polariser
I finally have a 24mm 2.8 in my possession after about four months of
various problems. I'll be getting to grips with it over the holidays during
the 8 hours of light that we get at this time of year in the UK (I'm sure
it's a lot more than some on the list, but still seems mighty short to me -
do we have anyone north of the Arctic Circle?). I seem to remember someone
saying that polarisers can be problematic with this focal length as enough
sky can be captured that the darkening of the sky is seen as a band, rather
than a uniform effect. Is this right?
