I like both Pentax SMC and Hoya HMC filters (and, I've found the Hoya HMC's easier to clean). I've never tried a Hoya SHMC - it does sound like a marketing ploy - <g>. I once tried getting a couple of Heliopan filters but could not seem to locate multicoated ones, so I gave up. I don't use filters all the time - I try to use filters only on frequently used lenses that see a lot of outdoors service. Fred
