i recieved a 24-40mm F3.5 Sun lens in the post today, it appears to be in almost brand new condition (nice big front element, no scratches,etc) and the focus ring is verrrrrrrrrrrrrry smooth however the zoom ring is hard to turn, it's smooth but hard throughout the focal length as if something is overtightened, any ideas?
