Ditto...


With really wide angle stuff, I worry about polarizing filters simply because the effect changes significantly with angle of view, i.e., blue sky becomes different shades, etc... if I had a problem with vignetting, and I couldn't fix it by stopping down, I'd remove the UV filter, I guess.
