I ordered filter with the filter adapter to my Delamax IR. At first I was skeptical that such a low-priced product can be good. When I unpacked then I noticed strong odors which equal but vanished. Then I screwed the individually packaged filter all together. This I repeated several times, as it initially stuck something. But then it went well and I'm now really happy. The rings are made of aluminum probably, therefore they should be when not in use turn from the lens mount and keep the rings separately, otherwise 'eat' them a. This is chemistry and even with other rings so has nothing specifically to do with the product. Can anyone who is occasionally used to filter different sized lenses rings. If you like working with filters, should take adapter made of brass.
