This is an OLYMPUS 45mm prime lens. It comes with the original box, but the warranty has expired as it was purchased several years ago. I've only used it about twice at home and never used it outdoors. There's a small scratch-like mark on the cap, but the lens itself is clean. ^_^ - Brand: OLYMPUS - Model Name: M.ZUIKO PREMIUM - Type: 45mm prime lens - Included: Original box
