Carl Zeiss Jena Biometar 80mm F2.8 Telephoto Prime Lens Silver. Condition is MINT. Very smoth focusing and diaphragm. 2 tiny bubbles in the lens (some consider them a sign of quality) and some dust. I notice a slight fogging of the lenses. The lens is not disassembled to clean the optics.
Converting to Canon EF mount is professionally done and has an infinity focus.
The last 3 photos were taken with this lens at f/2.8
Lens come with front and rear caps. ( And a cardboard box )
