This is a Tokina AT-X AF 17mm f/3.5 wide-angle prime lens. There is no mold on the lens. There is some clouding on the edge of the rear element, but it's on the edge and I believe it's outside the area that would affect photos. Other than that, it's in very good condition. I've attached it to a camera body and confirmed it's working. The autofocus works without any problems. It's for Nikon F mount. I'll include a Nikon filter. The hood is built-in. *This is a vintage item. Please refrain from purchasing if you are overly concerned about condition.
