With regard to the issue with which multiple granular dust spots are
reflected in images captured with the D600 digital SLR camera, Nikon
sincerely apologizes for any concern and inconvenience suffered by D600
users, retailers, and all concerned.
Because Nikon takes this matter very seriously, we will continue to
offer users of the D600 a special service with which cameras are
inspected, cleaned, and if necessary, shutter and related parts are
replaced free of charge, even after the product warranty has expired.
However, if a number of multiple granular dust spots are still
noticeable in images captured with a D600 upon which the above service
has been performed several times, Nikon will replace it with a new D600
or an equivalent model.
Nikon will continue to work to improve the quality of its products and services even further.
We hope that you will continue to choose Nikon products for your photographic needs.
