Query: Perfect

This is perfect for my new Olympus E-PL1. I bought this to protect my lens and, for that, it's perfect.Personally, I don't see any difference in my pictures but I'm very amateur and haven't done any tests.Note: I received mine with a very small crack at one point at the rim of the glass. It's like someone twisted the metal band a little and caused a small pressure crack. It doesn't show up in any of my photos so I didn't return it.personally:Perfect lens protection for the price (compared to olympus' 40.5mm for $30).I would recommend it to anyone
