We would like to offer our sincere apologies to users who have been inconvenienced by this issue.

This phenomenon is confirmed in images recorded in both the RAW and JPEG formats.
In the RAW file, the image corruption may appear in the bottom right corner of the image.
In the JPEG file, the image corruption may appear in the lower third area of the image.

Please Note:
Movie recording is not affected by this phenomenon.
Still images or movies recorded to CF cards are not affected by this phenomenon.

All new EOS-1D X Mark II cameras distributed by Canon Australia and Canon New Zealand after June 27th will have firmware Version 1.0.2.

We would like to apologize for the inconvenience, but we would like to ask our customers to refrain from using SanDisk CFast cards when shooting still images until the new camera firmware becomes available.
