Question about 100mm macro IS f2.8

Just a simple q's for 100mm L owners.

1) Do you have a slight free movement of the focusing barrel? It doesn't change the focus, it just feels a bit loose. But when you actually rotate it, it's normal.

2) I'm not 100% satisfied with its AF on 7D. I blame the 7D. For example, when I use af-servo mode on a still subject and I don't move at all, I usually hear slight tick-tacking of its AF, rotating the barrel slightly to the let and right, trying to nail the focus. Strange, since neither the subject nor I move at all. Do you also experience this?

Thanks.
