We have recently found that in some EOS-1D X units, there is a possibility that the following phenomena may occur due to wear caused by insufficient lubrication within the camera’s driving mechanism.
Although the possibility of insufficient lubrication is low, we choose to proactively inform you about this with Canon priority support actions to ensure the product quality.
Phenomena:
1. AF searches but does not lock in on the subject. (Caused by minute particles produced by wear mentioned above.)

)
2. The image shown in the viewfinder is “blurry” or “not steady”. (Occurs if wear progresses.)
Potentially Affected Products:
If the sixth digit of the EOS-1D X ‘s serial number is “1”, “2”, “3”, “4”, “5”, “6” or “7”, the phenomena described above may occur.
CPS Priority Support:
The free of charge inspection and repair (if necessary) of potentially affected cameras will be starting from 24th June 2013 (Monday).
Please call CPS Hotline at 2170 2860 for priority registration of inspection service.
We have also prepared backup EOS-1D X units for you to ensure your work will not be interrupted.
