In an earlier thread on here, I was told I could possibly use Cokin filters on my camera. I have a Canon Powershot SX10-IS. I was wondering if anybody knows which kits work for this camera. I'm mainly interested in a polarizer. I don't know much about the filters at all, except that they connect to the tripod mount. How do I tell if the mounts will fit the camera? Can you provide a link, please? Thanks a lot.
