FAQ: Important announcement regarding EOS-1D X / EOS-1D C [Added 18 June 2013]


Due to inconsistency in the amount of lubrication which has been applied to the driving mechanism, we have identified a phenomenon in which a small number of the affected products listed below, may over time, develop the following symptoms:

  1. AF searches but does not lock in on the subject. 
    (Caused by minute particles produced by wear due to the inconsistent lubrication mentioned above)

  2. The image shown in the viewfinder is “blurry” or “not steady”. 
    (Occurs if wear progresses)

Helpful Information:


Identification Procedure:

  1. EOS-1D X: If the sixth digit from the left of the serial number is “1”, “2”, “3”, “4”, “5”, “6” or “7”, the phenomena described above may occur.

  2. EOS-1D C: If the sixth digit from the left of the serial number is “1”, the phenomena described above may occur.

NOTE: If the camera’s battery compartment contains one of the markings illustrated below, the camera is NOT affected by the phenomena described above even if the sixth digit of the serial number is one of the numbers mentioned above.
