I just got off the phone with Green's Camera Tech about my 18-200 VR. They still don't have the part from Nikon. I dropped the lens off with them on May 23rd. According to the rep on the phone, Nikon is having problems across the board. It's not just lenses, but they can't get parts for camera, whatever. Any clues as to why Nikon is having so much difficulty producing and delivering parts to repair shops? She says they've spoken with other authorized repair centers across the country and they're all facing the same problem.
