Jim, thanks for your response. I guess there's no standard protocol for checking out a new camera. Certainly, confirming focus is important. This was a problem in the D800. I hope I get the camera before April so I have time for both learning how to use it and looking for glitches. I know we'll be in a bit of a panic before our trip and really want to square away any camera issues before that. Congratulations on the grand sons. You'll have years of following tthem around with your camera.
