When I bought my 24mm, I also purchased the Heliopan thin circular PL. My
one regret - it does not have outer threads so while the polarizer is on the
lens I cannot attach the lens cap. For the 24, as I found out using another
filter, I could have gotten the normal filter w/o any vignetting occuring.
Oh well. Live and learn. But you are going even wider. You might try a
normal UV and see if you get any vignetting. That would tell you if you
need the thin filter or not on that particular lens.

Thanks Aram. I too am thinking of the thin circular polarizer. I'll call one of the dealers and let the group know about pricing, advice, etc., etc.

Actually, the "magic" appears AFTER you attach the filter. No magic in the actually attaching. Just grab the right filter size and screw it on. Lens doesn't matter. The way the camera body handles the light does. As Doug said, any camera with a beam splitter for metering or auto focus will give inconsistant results with a liner PL filter.
Also, watch those skys with a very wide angle. Since the angle of light between the source and the camera determines the degree of polarization, wide angles often have part of the sky showing more of an effect that the rest of the sky. And as with any filter, watch out for cutting the corners of the image by the filter ring. Might need a extra thin version.

Might I ask a quick question regarding polarizers and two of the R lenses? With reference to both the 21-35 Asph, and the 28-70 zoom lenses ( not the uncommon Asph version ), is there any magic to using the polarizers? Does one simply obtain a circular polarizer of the correct size, and screw it in?
Sorry for asking what must appear to be a very simple question.
Elliot
