ohhhh thats interesting. So it means adjustments can be done at shop rather than sent all the way back to Snikon.
Really wish they would drop the VR off their lenses and just move it into the camera bodies to help reduce the size of lenses and possible defects.
No, shop keeper’s can’t move anything.. Nikon service center can. These modules are not adjustable by users.
