It has been confirmed that when shooting still images with the EOS-1D X Mark II digital SLR camera launched in April 2016 with SanDisk CFast cards, the following phenomenon will occur.
We would like to offer our sincere apologies to users who have been inconvenienced by this issue.
If a SanDisk CFast card is inserted into the camera or a card reader, the bottom part of still images recorded may be corrupted.
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.
Movie recording is not affected by this phenomenon.
Still images or movies recorded to CF cards are not affected by this phenomenon.
This phenomenon is caused by SanDisk CFast cards. The camera does not cause this phenomenon.
SanDisk CFast cards.
Image corruption may be experienced with the cards listed below:
The “xxx” at the end of the product number varies depending on the sales region.
SanDisk Extreme PRO CFast2.0 64GB (SDCFSP-064G-xxx)
SanDisk Extreme PRO CFast2.0 128GB (SDCFSP-128G-xxx)
SanDisk Extreme PRO CFast2.0 64GB (SDCFSP-064G-xxxA)
SanDisk Extreme PRO CFast2.0 128GB (SDCFSP-128G-xxxA)
SanDisk Extreme PRO CFast2.0 64GB (SDCFSP-064G-xxxB)
SanDisk Extreme PRO CFast2.0 128GB (SDCFSP-128G-xxxB)
Although it has been confirmed that this phenomenon is caused by SanDisk CFast cards, to prevent the occurrence of this phenomenon, Canon is considering releasing camera firmware on the Web for a download service in early July.
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.
It is our understanding that image files about 16MB or less recorded immediately before the camera’s power is turned off may become corrupted. Below are the methods available to help avoid image corruption when powering off the camera:
The Camera can be powered off in four ways:
The phenomenon can be prevented by performing the procedure below:
Before powering the camera off, please take extra shots*1 because the extra shots taken immediately before the camera is powered off may experience the corruption and not the images taken before the extra shots were taken.
*1 The table below shows the most popular file types used and how many extra shots are recommended.

Canon is working on a firmware upgrade for its 1DX Mk II after it discovered a number of SanDisk CFast cards corrupt still images.
Canon Australia issued a service notice warning 1DX Mk II shooters to avoid SanDisk CFast cards, explaining that the bottom part of RAW and JPEG images appear corrupted when using Extreme PRO CFast2.0 64GB and 128GB cards with a certain product number (listed below). Movie recording is not affected.
The company confirmed the phenomenon is caused by SanDisk cards – not the Canon camera – however firmware v1.0.2 will be available in early July, and any IDX Mk II cameras distributed after June 27 will have the firmware. (But if the SanDisk cards work in other cameras, and the problem is fixable with a Canon firmware upgrade…)
