Don't get me wrong - I still wouldn't be caught without my polariser,
and the effect can be used to advantage.. There's an example here,
second image down (and I've seen much more exaggerated cases!)

Thanks for the comment. Yes, it is a polariser that I planed to use. I
didn't realize it would have odd gradations at wide angles. Thanks again.

That's a fact of life, which doesn't mean that you should no use a
polariser filter at wide angle or for panorama sequences.

Regarding the question whether the polariser filter vignets the image,
this should be the case to a certain extent, but can be taken care of in
post-processing. However the major issue is that the wide angle
converter for the R1 is huge and adds to the weight of the R1, making it
even more bulky.
