This is the Tokina AT-X AF 17mm f/3.5 wide-angle prime lens. There is no fungus in the lens. There is some cloudiness on the edge of the rear element, but it is on the very edge and I believe it is outside the range that would affect image quality. Otherwise, it is in very good condition. I have attached it to a camera body and confirmed its operation. There are no issues with autofocus or other functions. This is for the Nikon F mount. I will include a Nikon filter. The hood is built-in. *Please note that this is an old item. Those who are sensitive to such things should refrain from purchasing.
