Lens deterioration - Is this element separation?

[Oldhand]

Hello lens gurus.
I am interested in the possible problems with this lens. There is evidence of some possible deterioration in this lens as seen on the edge of the elements. Is this simply a loss of blackening or is it the beginnings of element separation.
Or is it something else - - or nothing at all?
This is the only image so I hope it is clear.
Thanks

So called "Schneideritis", deterioration of the blackened out areas and possible condensation of that stuff elsewhere.

NOT lens separation, relaxe!!

Thank you Klaus.
Good to know.

The first time I see a lens with "Fujinonerities"... The - by far - more common is Schneideritis,

OH, don't worry, the lens will perform as expected with this internal small paint loss,

Cheers,
