Just received my Fuji 55 - 200mm and I notice that when I turn on the camera I can hear what sounds like the VR motor continuously running. I then take a shot, delete it, and the motor stops; then runs continuously when I depress the shutter release button halfway again. This happens whether the VR switch is on or off. Don't think knocking it on a hard surface to fix the problem is a good idea! Anyone else had the same experience?
