Schniederitis

[jd callow]

I posted an (there was a url link here which no longer exists) in the tech gallery. It has 'bubbling' where the lens element is cemented to the barrel. Is this Schniederitis and how does it effect the image taking and value. I'm going to sell this lens for a friend and would prefer not to have to run film through it.

Schneideritis is normally acknowledged as being a flaking of the black coating on the interior of the barrel and does not affect image quality.

When I looked at the image of the lens, it does not appear to be separation but rather a flaking of the coating. Your image shows this spotting on the lens elements themselves too. I am not sure if this is showing through the elements or on the elements.
