Well-known
There was a place on the rear element where the paint had worn off due to whatever camera it had been used on before I got it. Being on an external part it was easy to recover. Took me a while to realize it wasn't a camera leak that was causing my problems.

Would you think very small damages to the paint there are significant? Mine is missing under a mm² in total... Then I should probably also touch it up.
