I just purchased the EF-S 10-22 and EF-S 17-55 lenses and I'm looking to get protective filters for them. I've been reading quite a bit regarding lens filters as, at least for my budget, I have invested quite a bit of money in my new lenses. The recommendations always come back to B+W and Hoya. I have found very little in regards to the protective filters made by Canon (or OEM'd - Canon product support said they made them, but not sure if they consider OEMing "making" them), or rather, any filter made by Canon. Are there any online reviews I can see, or has someone done a comparison between Canon and other brands? I like to research before I buy and I figure that a Canon product would work best on a Canon product, but it concerns me that most people are purchasing other brands. What can I say, I over analyze but I'd rather buy right and buy once and not have shoppers remorse. Any guidance or information on Canon filters is appreciated.
