The fully functional D800 AF thread - drop a line!

I can understand your hesitancy, with so many stories -- including my own -- of cameras coming back from the "repair" in worse condition than they were in to begin with, then requiring repeated efforts to achieve a satisfactory result. I'm thankful that I work within driving distance of a Nikon Canada location, allowing me a more rapid and face-to-face interaction. It will also allow me (from now on!) to check the camera's functionality in the presence of Nikon staff before leaving the building with it.
