RAYNOX PRO SEMI FISH-EYE 0.3x. I used it a few times and it was sitting unused at my parents' house for quite a while. I used it for skateboarding photography, but I got busy with work soon after I bought it and didn't use it much. It comes with a case, but the case is sun-faded. The lens looks to be in good condition with no scratches. I'm selling it to clear out my parents' house. Please purchase only if you understand.
