[ UPDATES TO SERVICE ADVISORY - 10 April 2014 ]
To users of the Nikon D600 digital SLR camera
Thank you for choosing Nikon for your photographic needs.
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 makes 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, as stated in our "To users of the Nikon D600 digital-SLR camera" posted February 22, 2013, Nikon has been offering a service that includes examining the cameras thoroughly and servicing them as needed when users were still experiencing the problem.
In addition, since February 26, 2014 announcement, we have offered a service that includes the inspection, cleaning, and replacement of the shutter and related parts even after the product warranty has expired. This service has been offered at no charge, and all shipping costs, both to and from the Nikon service center paid by Nikon.
Today, we announce that we will further expand the service available to users of the D600 as follows.
