I agree that polarisers don't give an uniform filtration on superwides. However I found that the results are often better than without one on my 20/f3.5 and 18/f3.5. The colours might be rather surreal and not up to everyone's taste, but I rather like them. I read somewhere that B&W and Helipopan make special (and expensive) polarisers for wide angle lenses. Has anyone tried them, or know their web sites ? Happy shooting, Sover
