I've been looking for a pair of good 58mm UV filters to keep on two new Canon EF lenses. Canon, of course, would rather that I used their own product, but I've also heard many good remarks about Hoya and Tiffen multi-coated UV filters. Can anyone tell me anything about how the Canon UV stacks up against B+W, Hoya HMC, etc.? <p> Thanks, <p> R.D. Hight Not part of a cosmic energy field per se.
