i dont see any vignetting using a low profile filter on the sigma 10-20mm.
however i do see vignetting appearing at 10mm if you use the cokin p system wide angle holder... adjusting to 11mm should solve the problem.

By getting more vignetting from the filter holder because of the wider angle of the lens? :dunno:
