Canon has issued a firmware update for the 1D X Mark II that addresses the recently-published image corruption problem with certain SanDisk CFast 2.0 cards. The firmware update specifically provides the following improvements:
- Incorporates countermeasures for a phenomenon in which the bottom part of still images recorded to SanDisk CFast cards become corrupted.
- Enhances communication reliability between the camera and CFast cards.
If you are using the affected CFast cards, after having updated the Camera Firmware to Firmware Version 1.0.2, please make sure to use the camera to format the CFast card.
You can download the new firmware update here on Canon’s website.
