Looks like the hot new Nikon D600 is already facing a potential problem. Roger Cicala from LensRental.com is reporting that dust kept on reappearing with the 20 D600s that have been rented recently. Although dust can be fairly common, what LensRental noticed is that not only was this consistently happening, but it was generally happening in the upper-left 1/3 of the sensor.
Roger said that the spots are dust specs, and not oil, but there are other photographers who are getting oil spots in their D600s, too.
Roger also said that the potential culprit may be the larger-than-usual shutter curtain opening compared to other Nikon cameras.
Is this going to be a bigger issue worthy of a Nikon recall?
