Review on Professionally Multi-Coated 58Mm Lens Filter Kit With UV, CPL, And FLD Filters, Miracle Fiber Cloth, And Carry Pouch - Compatible With Nikon And Canon Lenses With 58Mm Filter Size by Mario Beckwith

As many of the other reviews have pointed out, you can certainly buy better quality filters than these, but not for under ten dollars.My filter set arrived in a divided leather carrying case and each filter was individually sealed in it's own cellophane bag; new and clean (no smudges, dust or fingerprints).As far as build quality goes the three filters are not consistent:1) The UV filter is "heavy" and "cold" and makes a ting when tapped with a fingernail, giving the impression of an aluminum ring and glass optics. Since I am using this primarily to protect the front of my lens, I am glad for it's sturdier build. As far as it's optical qualities, it seems perfectly clear to me and does not noticeably affect the quality of my digital photos.2) The FLD filter is "light" and "warm" and makes a thud when tapped, giving the impression of a plastic lens in a plastic ring. Given that I don't often shoot with film and that when I do use film, I'm usually outdoors anyway, I will possibly never use this filter and am unconcerned with its quality. (This filter's application is for correcting white balance when shooting with film under fluorescent lights, digital cameras will correct the white balance digitally)3) The CPL filter is difficult to determine, it feels like aluminum and glass, but less so than the UV filter does. It might be heavier plastic, it might be lighter glass. What's important is that it threads easily, spins easily (but not so much that it spins out of where it's been set on it's own), and does an excellent job of cutting glare and deepening the blues of the sky.Overall, if I only got the CPL for my $8, I would still give this set 5 stars for the value. Having a sturdy feeling UV filter to protect my lens is a great plus.
