I might be too paranoid, I admit. Only because it seems there are just too many people complaining and/or returning their D600's to Nikon for cleaning or for outright return, i.e., too many for my very own comfort. Chances are I will be keeping the camera, and I know I will have to learn to clean it on my own as I cannot afford the shipping charges back to Nikon. Especially if I have to do it more than once. We shall see.
