I have a UV filter on my Sigma 10-20 and I don't get vignetting.

I use a UV filter for protection. I only remove it to use other filters, because sometimes doubling up on filters will cause vignetting. Never leave your lens naked.

I agree with Laurin and do not use UV filters. As a matter of fact, just about any filter can now be duplicated in Photoshop. The only filters I use are a B&W Kaeseman Circular Polarizer that I use for waterfall & landscape shots which control water reflections and allow more detail of darker areas & the CP filter cant be duplicated in PS and occasionally a ND filter. And I only use the best since I am placing it over an L glass.

Just tried to see if what you were recommending is for mostly studio use, or with your choice also be applicable to sports...fast action shots outdoors.
Periodically I have issues when the sun is over head in a cloudless sky.....tried my usual UV filter and the images were not as tack sharp.
Also where do you buy yours as the only 81A I could find online at Penn Camera and B and H was a ProMaster version.
Thanks
