Nikon Inc. is asking your cooperation in resolving an issue affecting certain D800/D800E DSLRs. This issue manifests itself when you utilize the left bank of autofocus points, resulting in slightly out of focus images. This issue has been traced to instances of the autofocus mechanism alignment being outside of the engineering specification tolerances. While there have been a number of confirmed incidents of the problem worldwide, Nikon cannot yet confirm the total number of units affected. Nikon can confirm a range of D800/D800E units within certain serial number ranges that may be affected by this issue.
Nikon’s Engineering teams have made the appropriate calibration change to the manufacturing equipment and included an additional quality assurance test to prevent further occurrences of this issue. For D800/D800E DSLRs affected by this issue, Nikon has developed and implemented a reliable means for Nikon Service Center technicians to diagnose, fix, and validate the repair. Nikon has dispatched trained technical teams across the country to work closely with each of Nikon Service Centers and customers to expedite the resolution of this issue.
I got this email from Mansursovs.
