Nikon D600 Dusty sensors

Mine has dust/oil on the sensor as well. I'm super happy about most aspects of this camera, love it,  but this set-back makes me sad. I've contacted Nikon and they asked me to send the camera in. I just might do that, but I'm sick and tired of sending my cameras to Nikon to get fixed. Really hoped this one would be problem-free. At least it has no focusing issues! Photo was taken at f/22 with 70-200mm VR and flash. Spots are barely noticeable wide open (expect for that very dark one in the center). Of course now that I know they're there, I see them in many of my photos. The problem is real.

f/22 + flash
