High Quality Lens Protection
Crutchfield Customer Review (What's this?)
Excellent filter that provides some UV reduction when photographic outdoors. More importantly protects very expensive Glass (high quality lensed) with out compromising the reasons for having these superior lenses. As an example I use this glass on a Canon 70-200MM F2.8 IS L lens.
Pros: Quality Glass at a fair price
Cons: None, This is a good product.
