Trioplan 3" (75mm) f2.8 cine lens for 16mm.
Glass has some light haze, a tiny little bit of edge fungus, dust but in honesty the glass isn't too bad at all.
I haven't attempted to clean glass but should be quite easy to clean.
Focus is fine, aperture clean and working.
C mount.
No offers please.
Please ask any questions.
