Firmware Version 22.214.171.124 incorporates the following improvement:
- Supports exFAT file system of CF cards over 128 GB, which decreases the waiting time required for accessing the card before being able to record footage.
Firmware Version 126.96.36.199 is for XF105 and XF100 camcorders with Firmware Version 188.8.131.52 to Version 184.108.40.206. If your camcorder's firmware is already Version 220.127.116.11, it is not necessary to update the firmware. Once the camcorder is updated to the latest version, it cannot be restored to a previous version.
Please update the bundled Canon XF Utility application to Version 1.3 or later so that video clips that are recorded with Firmware Version 18.104.22.168 or later can be correctly recognized by the application. Download the Canon XF Utility for the XF105 or XF100.
