There's some separation on the Tessar 45 on my ZI Contaflex II. Mr. Jon Goodman who frequently makes wry (and quite funny) comments on these forums, and who used to repair Contaflexes et. al, said that lens-separation is pretty common among these models. Mine shows it just around the edges. I have not noticed any effect so far, even shooting in full sun (though not INTO the sun I'm conscious of the separation but not overly careful). The lens is still a firecracker, despite its elements' marital problems.


Here's an example from a roll of Ektar, processed by Walgreens.
