Jim, you read it right the first time; I did mean my camera lenses. Good point, well made.

Ed, All my lenses wear Hoya HMC Skylight 1B's (almost as clear as UV's, but with a little added warmth which I find pleasing) and the only time they ever come off is to gently flick away dust particles (how the *heck* do they get in there?!) with a very soft brush.

You are of course right. Let's put this down to a temporary aberration on my part and move along!

Thanks

Frank
