Yes, that's the case of the 28-135 IS in the wide end. You can see the dust deposits inside the lens!! :-) I sent it once to re-repair after they returned it with a considerable amount of dust in the inner elements. I had to mount it on the extension tubes to show to the guy at the camera shop how much dust there was.
