As much as we tout the reliability and quality of Leica lenses, I have found
that they are sometimes prone to slough of the anti-reflection coating. I
had a 90 Elmarit-R which I sent in to have modified with a third cam- within
two years, there was a considerable amount of black flaky stuff on the
inside of the glass. I did send it back, and they repaired it with no
hassle, though they did not apologize for nor explain the reason for the
flaking. I put it down to a bad batch of paint.... if this was a new lens-
it does not bode well for whoever supplies their matte black paint!
Good luck!
Dan
