Where does the dust go? With Olympus, the dust is collected on some kind of adhesive film that's to be replaced every 3 years, as recommended. For the sceptics: one of the big reviewers/testers has been shooting with this Supersonic Wave Filter for over a year, and says he never noticed a sign of dust on his images... That's okay for me... ;-)
