Up for auction is a Canon 17-85 f4-5.6 IS USm lens. It comes with hood (EW-73B) and caps (actual canon caps). I got this and the previous owner said it gave an error on their camera. I tested it on a Canon T6i and showed no error. So it may be fine, but there may be an erratic issue (they had an older XTi body). Cosmetically in very good shape. Zoom is a little sloppy/loose, and optics are clean (some surface dust).
