UV filter for wide angle?

[magomago]

Well I recently went on a trip, and at the last second I decided to take a polarizing filter just to slap on the front of my lens. I'm VERY glad I did, because my glass would have been destroyed by the harsh environment.

Now I'm looking for a UV filter for my wide angle 16-45, but I do not want (or if i can minimize it...) vignetting at the wide angle.

Does anyone have experience with http://www.amazon.com/B-W-Viol...&qid=1228490961&sr=8-3 ?
Will it vignette?

Is there another filter (either the same price or cheaper...I'm not too keen on going more expensive) that works?

Thanks in advance

are you running a 5D or other 135 camera?

Pentax yo K100D, so a 1.5x crop

then 16 isn't ridiculously wide angle and so you don't need to worry about vignetting as much as you would with a 10-20 sigma. if you're really concerned, hoya makes filters with low profile frames. you can't screw anything into the front of them, however.
