Cokin v Wigma lens

Hi Everyone,
Is anyone using a Cokin P filter system on a Sigma 10-20mm lens. If so can you see the edges of the holder, or is it ok at 10mm.
Thanks.
Ian

You will need to use the single-slot holder and that will not vignette.

I have a 3-slot Cokin holder, and it does vignette at the really wide end. I usually need to zoom in a little to around 14-15mm (not sure exactly) to keep the edges from showing.

As the previous person mentioned, you can get thinner single slot holders that wont vignette. I got my holder and filters for like $2 when a local camera store was going out of business, so I havent bothered to buy a replacement.

Thanks both for taking the time to reply, I appreciate your experiences of this set up
