Below is the first part of an article by Felix Esser from It reads…

Shortly after Nikon’s D600 hit the market as one of the most affordable full-frame DSLR options, users began complaining about issues with dust particles on the sensor. While each lens-change operation potentially allows dust to enter the camera and settle on the sensor, it usually takes a while until specs become visible in images taken at small apertures. And of course, with a brand new camera, there shouldn’t be any issues at all. With the D600 there apparently were.

Nikon’s initial reaction was to advise customers to visit their local Nikon service centers to deal with the spots. Usually when having a camera sensor professionally cleaned, dust spots should disappear. With the D600 though, they kept coming back. At some point, it became evident that the specs were in fact not dust, but oil that was spilled onto the sensor from the shutter mechanism, which pointed to a faulty shutter unit.

Oil spots decreased somewhat after a few thousand exposures, but professional photographers relying on the D600 were left in a lurch: though Nikon recognized the issue with a service advisory in February of 2013, the oil spots returned after service for some users. Eventually, rather than replace the shutter mechanism and continue manufacturing the D600, Nikon decided to simply introduce a new camera with a modified shutter: the D610.
