I've never had this problem with mine but I can see it possibly being the problem if you don't get the focus ring fully engaged. Also the auto focus on my lens was off when I first got it. It required a -13 AF fine tune. I sent it into Tokina and it came back spot on. BTW my turn around time is very quick. You may not have this problem but you may want to check your lens out for accurate focus.
