After about 10 months battling what I thought was soft focus, I finally sent my D800 off to Nikon for repair (LA location). The bright side is i spent the last 10 months blaming my technique and there's a chance it got better! Only 2.5 weeks later it's on its way home with delivery scheduled for Thursday. The repair order said major parts were replaced but were not specified. I never tested for the left focus issue. My camera was an early build which I received the week they started shipping.
Now my fingers are crossed and I can't wait to start playing with it again!!
