"I wanted to buy a D600 but will not buy one because of the dust issue.Good luck with your decision."
Actually I might have to eat my words. I just dropped my D700, it needs to be sent to Nikon (mirror not moving anymore) and I need a camera quickly to go to the north of Norway to(hopefully)shoot the northern lights. So I might byte the bullet and buy a D600 (with a reserve of eclipse and pads). Jean-luc
