EOS C70 Firmware Update version 1.1.4.1

19th August 2026

Thank you for using Canon products.

Changes:
Firmware Version 1.1.4.1 incorporates the following fixes and enhancements:

1. Adds compatibility with the "CINE-SERVO" cinema lenses CN30×40 IAS J/R1 (RF mount) and CN30×40 IAS J/P1 (PL mount).
When connected to external devices using the XC protocol, if the T value is 10 or greater, only the integer part is displayed on the external devices.

2. Fixes an issue that may interfere with the camera’s ability to connect to an FTP server.

3. Improves operational stability.

For details, please refer to the user manual (latest version) for this product.

Caution:
- Please use an SD/SDHC/SDXC memory card that is 512MB or greater to perform the firmware update.
- Firmware version 1.1.4.1 is for updating cameras running firmware version 1.0.0.1 - 1.1.3.1. If your camera's firmware is already version 1.1.4.1, it is not necessary to update the firmware. Once the camera is updated to the latest version, it cannot be restored to a previous version.
- Please refrain from loading menu settings generated using the most recent firmware version to a product running an old firmware version, as doing so may affect camera operations.
