Canon Ultrasonic 17-85mm F4-5.6 IS with Canon EF-S Mount.  The lens is used and shows average wear for its age. Aperture functions correctly.  Autofocus functions, but “hunts” quite a bit and really only works correctly when manually focusing.  I’ve adjusted the price to compensate for this issue.  The glass has some marks and dust associated with age, but appears to be clear of fungus, mold, and haze.   Includes one end cap and a filter.  I mounted the lens on a digital SLR and took the photos of the flower in the listing.  The lens functions correctly. Shipment to the United States only. Delivery tracking provided.
