Hi All, I have the 28-135 USM IS and have a problem with it. The zoom is creeeping very easiely and now the zoom blocks at times. The range is restricted to say 135-70. At 70mm it blocks as if it were the end of the zoom range. This may change and the next time it blocks at 55mm. Anybody else encounterd this problem? What is the fix? The lens is not even two years old and as I'm not a professional its only used at most twice a month.I contacted Canon New Zealand but have no reply so far.
