Took it out of packaging [which was well done] and immediately it felt sticky. The whole of the focussing ring had an unknown sticky substance on it. Started to clean it off [which wasn't easy] and noticed the F stop failed to stop at either end of scale and continued to turn. At that point decided not to attach to any of my equipment and returned. Currently waiting for refund to appear in bank account.
