This Rokinon/Walimex Pro Cine 24mm T1.5 Cinema Prime Manual Lens Micro 4/3 Cameras is in very good condition, with clean glass on both sides.
It's a great lens for your Micro 4/3 camera (Panasonic GH6/GH5, Olympus MFT, BMPCC 4K).I allow returns on a case-by-case basis if you find something is not as described.
