Free Corrective Servicing (Dust Spot Cleaning) for Nikon D600 Ending
From Nikon Europe:
On February 26, 2014, Nikon released a Service Advisory informing users of the D600 that Nikon would provide corrective servicing, free of charge, of D600 cameras exhibiting a particular issue.
This announcement is to inform users of the D600 that requests for this free corrective servicing will only be accepted until January 10, 2020.
Service to address this issue requested after the offer of free service expires will be handled in accordance with standard Nikon repair policies.
If you would like to have your Nikon D600 inspected for this issue and corrected as needed, at no cost to you, please request the service from a Nikon service center as soon as possible.
Some users have indicated the appearance of multiple granular dust spots in images captured with the Nikon D600 digital-SLR camera. These granular dust spots are reflections of internal dust generated with camera operation, or external dust particles that have found their way into the camera, either, or both of which, have adhered to the camera's low-pass filter.
While the structure and concept of digital-SLR cameras make the complete elimination of these dust spots very difficult, it has come to our attention that, in some rare cases, they may be reflected noticeably in images. Therefore, Nikon is informing users of a service to reduce this issue again.
