The Trouble Repor(t): Nikon D600 sensor dust issues?
Lens Rentals rents camera gear and that gives them feedback on potential issues and problems with various cameras and lenses. After renting out the Nikon D600 for a few weeks, they have noticed a pattern: one of out of every four of their twenty D600s for rental needed sensor-cleaning after just one rental. Sure, some photographers may be using rented cameras like rental cars, but still, the numbers are higher than randomness which is what prompted Lens Rentals to publish these findings. This was also cross-posted at Imaging Resource.
