Thin or normal filter on Sigma 18-50/2.8 on 350D?

Tried searching with no luck, so I'd be grateful if anyone can tell me

if a 'normal thickness' filter creates vignetting on a Sigma 18-50

f/2.8 lens used on a 350D (or equivalent sensor size) body? - or do I

need to get a thin-profile filter?

 

Thanks.

I use a regular UV-filter on my Sigma 18-50/2.8 fitted to my 10D. The sensor on the 350D is a tiny bit smaller so you won't have any problems.
