Hi, I'm new to this forum and have already learned a lot from previous posts (This seems to be a really great forum!!). I'm looking into purchasing a polarizer and was looking at the Hoya Circular HMC Polarizer. I've gathered that with the Powershot G6, my choices are a 52mm or 58mm. What, exactly is the difference, is it just a size thing? Do I need a step ring for either of these? If i were to purchase a Canon SLR in the future, would I be able to use this polarizer with an appropriate step ring? Also, I began looking for filters on ebay and found this package:

I'm assuming that it's junk, considering the price. The filters do not appear to be as good as the Hoya filters, but I'm a beginner and just not sure. I don't want to buy junk, but I don't want to end up paying too much for a brand name.
Thanks for any replies!!
