I have quite a whim bought this set because I had nothing for my Canon EOS 1000D. DC in advance, I'm not an expert but only an amateur photographer. Experience with UV &. Polarizer I had made the early 90's with the internships. Especially the polarizing filter is still necessary for good shots. With the above set I was not disappointed, especially the polarizing filter works well. Even a layman can recognize the clean processing of the filter. The only problem with the UV filters (which one can indeed usually as protection to the lens.) (For example, late at night) In low light conditions could no longer to focus, the autofocus of Canon. If you take the filter off, he is working again. Conclusion. All in all a good buy. Sure there are higher quality filters, but not for this price.
