77mm CP filter

[rutty]

I've been meaning to buy a circular polarising filter for my Sigma 10-20 but it needs to be 77mm and I'm having trouble finding an affordable one. Any advise?

Amazon have some but the prices are a little off-putting. I understand that price often brings quality, but I'm a bit of a cheapskate and was hoping for something in the region of £30

I use this one Hoya Yeah it ain't the nice HMC's or the really nice B&W's but it's also only £35 and has served me perfectly well. I've not yet used it on my 10-20 but used it a lot on my 17-40 without any problems.

Cheers! That's more the price I was after.

I used my 10-20 a bit too much on honeymoon and I could have used a CP a lot of the time. Better late than never though

I did have a Hoya HMC one, but that fell apart while we were on holiday so I replaced it with Hoya Pro 1D one and the difference is noticeable (less/no flare). If you're happy to buy from ebay you can get it for about £65.
