Nikon issues service advisory on D600's dust issue

There have been numerous complaints about dust and dirt accumulation on the camera's sensor for Nikon's D800 and D600 cameras.  I have personally heard owners of D800 cameras say they had them serviced and I have read one specific review of a repaired D800 saying that the Nikon service guys were just using duct tape to solve the dust issue with pictures of the camera after it had been serviced.  Well now Nikon issued an advice for all affected camera owners to have their camera serviced mentioning specifically the D600 model. Here's the service advisory from Nikon's European Site.

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, Nikon is informing users of a service to reduce this issue.

Resolution
As a first step, please follow the guidance from the User’s Manual (pages 301-305) related to the “Clean Image Sensor” function and manual cleaning using a blower. If these measures do not remove all dust particles and you are still experiencing problems, then please consult your nearest Nikon service center. They will keep your camera, examine it thoroughly, and service it as needed.

Requesting service
Please direct inquiries regarding this matter to your nearest  Nikon service center.

We hope that you will continue to choose Nikon for your photographic needs.
