Filter problem

Just recently bought a Sigma 18-50 F2.8 lens which has a 72mm thread. I bought an adapter so that I could use my existing Cokin square filter holder. When I used it at the weekend I was seeing vignetting in the corners when the lens was at 18mm (with the circular polariser in the holder). I never has this issue when used on my 18-50 kit lens, I'm presuming its due to the wider glass on the front.

Is there a way around this, or do I need to buy a dedicated polariser before attaching the cokin holder on the end.

Re: Filter problem

Assuming it's the Cokin P series, is there already a screw-in UV filter on the lens? If so, taking that off will possibly cure it.

Re: Filter problem

Ian, buy a single filter holder, + just use one filter at a time. The single holder doesn't cost much, + well worth it to lose the vignetting If you want to use an ND filter in the Cokin holder then, yes I'd suggest, on the one hand, that you buy a screw-in polariser, if you want to use them together ... On the other hand, however, it's a bit fiddly to rotate the polariser with a Cokin filter holder fitted to it. Best solution would be to use a single holder + stick to one filter at a time, i.e. polariser OR ND filter. UV's are not essential unless you are at a particularly high altitude, e.g. on top of a mountain, so I'd say lose the UV in the first instance.
