Title: ASTOUNDINGLY CHEAP! BUY SOMETHING BETTER!!!
Review: Wow, I was very very very unimpressed with these filters. Not just mediocore, but there was dust on the lenses and you can tell by just holding them they are cheap as sin. PLEASE DON'T WASTE YOUR MONEY. IF YOU HAVE ANY HOPES OF TAKING AMAZING PICTURES, UPGRADE!!!
