I just got my nikon D70 kit a few months ago, its a great camera but after 2 or 3 lense swaps i noticed dust spots in my pictures. I've cleaned the sensor myself, twice now, with help from the manual, but the dust still sits there. Right now I'm searching for a place to send my d70 to be cleaned by nikon, but can't find any address or instructions. Can u guys please help me out? thanks
