Hi guys, I just bought my first SLR and would like to buy some filters for my lens. I came across this on amazon: 52mm Merkury Optics 3-Piece High Resolution Filter Set [ame]http://www.amazon.com/Merkury-Optics-3-Piece-Resolution-Carrying/dp/B000TO64RK/ref=sr_1_7/104-1325681-6121562?ie=UTF8&s=electronics&qid=1186268042&sr=1-7[/ame] It's only $16!:hail: Well, just wondering if anyone has used these filters before and if so, any general comments? Will poor quality filters do any harm to the lens? I know some things it's worth spending a lot more because you get a lot more in return, however, are filters really that much different? Any advice would be appreciated! thanks in advance. Waiting for a reply.
