Does anyone with the lens experience the ticking sounds disappearing for a while then coming back? For example, you hear ticking and put the lens down for a few hours, come back, and then the ticking is gone. But then you put it down again, come back a few hours later, and the ticks are back again? It seems random and I'm not sure what causes it....I don't think it's temperature since the lens is in the same environment the whole time.
Yeah I had a 03 (March) copy and returned it to B&H. It would have the ticking sound and then it would disappear. Then after moving the zoom barrel later you would hear it again so its possible.
