The glass is in excellent condition. No scratches, no cleaning marks. The glass inside of the goggle for the viewfinder has a very small internal chip (see photos).
It does not effect visibility through the viewfinder, but its worth mentioning. There is a small amount of haze in the goggle and would benefit from a proper cleaning.
Condition of the aperture blades. Leica Leitz ELMAR 90mm f/4 (Collapsible Version). No scratches, no cleaning marks, no fungus. There is a little bit of haze, and would benefit from a proper cleaning.
