[Leica] Bad luck with chrome 50/2 rigid Summicrons

[vick.ko at sympatico.ca (Vick Ko)]

I am running into a streak of bad luck with my 50/2 rigid Summicrons.

First, I find my old DR Summicron has coating degradation - a light 
fuzziness on the front coating I look closely at it.

Then I check a 50/2 rigid chrome lens - it has the coating degradation 
but to a lesser degree.  Then looking inside, it has concentric rings of 
some haze.  It doesn't look like the rainbow rings of doublet 
separation.  They look literally like large concentric rings of haze.  
Have you heard of this "rings" phenomena?

Both might be destined to the "bay "as is" sales category.   :-(

That or they are my "extra glow" 50/2's.
