I'm actually really excited to see what they do to my lens. I brought it in for a much needed checkup. It was not producing sharp shots at 400 wide open and at 400 I've been having to stop down to get it to sharpen up. I checked the status of my repair and they rated it a B2 repair job which is categorized as receiving major parts replacement! So I'm hoping my 200-400 VR will get a much need overhaul! Strangely, I've been using my Sigma 500 HSM as my baseline lens for telephoto sharpness. at 500 wide open, it put my 200-400 VR to shame, even when the 200-400 VR was stopped down. And the Sigma is supposed to be weak wide open. For shame Nikon! I also am having my 200 f/2 VR checked up and my D3 is getting a general check and clean!
