lens – Is this sound normal for a Nikkor 55-200 VR?

I just bought a Nikkor 55-200 mm 1: 4-5.6G ED for my D5000 and found out that if VR is enabled, two things happen after you press the shutter button halfway, wait for the lens to focus and release it:

  • I hear a loud click about two seconds later.
  • Along with the sound I can see the image in the viewfinder changing
    to one side a little bit.

The above does not happen if the VR is deactivated. Can someone with the same lens confirm if this is common or something to worry about?
