My D800 is on its way back from Melville after being sent in on April 19 for the left focus issue. I was coming up on the one year mark so it was now or never. So far everything has gone smoothly. I sent a disc with all my test shots (a subset of which can be seen in my nikonian's gallery). It was listed as a B1 repair with clean and check. It is currently listed as "bill" but UPS has sent a email that it will arrive tomorrow morning by next day air shipment.
Tomorrow's weather looks good for re-testing. Hopefully that will go smoothly as well and I will be reporting a successful left focus fix.
