hongsien said:Hoya filters come mainly in two fabrics regarding coating: single or multicoated. For multicoated ones there are several types as well, depending on the number of coating appllied. Many have problems cleaning HMC Hoya filters by the way, which however can be resolved by washing them in slightly warm water. They are all made from optical glass and are flat.
For wideangles one may use the ultra thin filters: two series available (one with and one without front filterthread), these are slightly more expensive.

HMC = multicoated, can read the Hoya catalogue or do a search for the Hoya site.....personally not interested in how many layers etc, as long as it is coated its enough for me..... you can look it up on the Net....it is there soemwhere.......reachme2003 said:clarification. is HMC one of the multicoated ones? if yes, number of coatings on it? thanks
If it is not HMC then it is single coated.......kababoom said:thks for the info but is there anyway to tell from the packing whether the Hoya filters are single or multi-coated.
