    It's possible to DIY recementing, as an option. Edmund Optics among other places sells the appropriate UV-curing cements. The main trick is removing old cement/balsam, and realigning the elements while new cement sets.

    I recemented a Rapid Rectilinear on a Kodak folder, using balsam harvested locally - direct from the tree. The only "treatment" I used for the balsam was to leave it in a warm dark place for a few days, until the chunks of tree settled to the bottom.

    Obviously, you don't buy lenses off Ebay often enough.

    Or even from 'reputable' dealers... you should look at the pile of 300 f/2.8s (35mm) I went through during the last 6 months... enough fungus to start a mushroom farm.

    Apparently not. I don't shop at WalMart either.

    Dear Lord no! I buy lenses from miscreants and reprobates exclusively.

    I once traded for a 9 1/2" Dagor/Compound, at a camera show. The Dagor has a gouge just about in the center of the rear element. That dirty rotten scoundrel relieved me of a pre-AI 50mm f:2 Nikkor-S, and he didn't even give me any India ink to black out the scratch! @#$$%@@#&%&##+&.

    I have never sold you any lenses!

    Are you sure that it isn't coating damage rather than lens separation? I'm looking at the manual for the Contaflex II and it shows a normal Tessar, with a cemented lens group in the rear, not in the front.

    I am not sure ... looks like lens separation and Jon seemed to think that's what it was.

    This is all I know.

    My Zeiss Ikon Super Ikonta 533/16 has this problem. The camera itself is aesthetically gorgeous but I really have to get it off to someone who knows these cameras well to get it back into operating order.
