Not sure what you are seeing, but the factory paints the edges of all 
lenses with a black protective paint.

I just bought a summaron 35mm 2.8 - was advertised as 'bargain' condition.

There is an irregular very thin rim of blackening around the periphery of 
one ofthe rearward elements.
I have never seen this before on a lens.

Anyone know what could cause this?
Fungus? Coating pulling off an element?
