The lens is in good cosmetic condition including the external optics, the glass is clear with no marks or scratches. Internally, there is a very small price of dust on the optics, as pictured. This does not impact image quality. The autofocus does not work. Until recently the image stabilisation worked, but now rarely works. I understand this is a common fault. When tested using a Canon 77D, the lens can be used in manual focus, with the camera recognising when the image is focus. It does produce great images when used in this way. There are no error codes when using the lens on the 77D. It is sold as parts, so the expectation is that the lens does not work at all.
