Those are bubbles in the black paint on the elements' edges. Harmless except to resale value. Often called Schneideritis.

Jason, they say nothing. The problem has been around since at least the 1950s. Boyer's lenses are worse than Schneider's. Fuji LF lenses have it too.
Not so fast, everyone.... There was a unique cementing issue with both 80's and 110's for awhile, a mfg flaw distinct from "Schneideritis". Schneider knew about it, and a number of lenses were replaced during the relevant warranty window. This kinda spoiled the reputation of these otherwise excellent lenses, though they corrected it. You'd have to know the affected batch per serial no. But they were glued in a different manner from most lenses due to the aspheric construction. "Schneideritis" is merely a benign failure of the rim blackening on the mount, unrelated to this issue.
