Google Translated notice from Canon Japan

To customers using the continuous recording function for professional video cameras and digital cinema cameras

Thank you for using Canon products.

We have found that the following phenomenon rarely occurs in the professional video camera “XF605” under specific usage conditions. We have also confirmed the possibility of this phenomenon occurring in the EOS C70 and EOS R5C digital cinema cameras equipped with the same functions. There have been no reports of this phenomenon occurring with the EOS C70 and EOS R5C.

We sincerely apologize for any inconvenience and concern caused to customers using this product. In the future, we will continue to implement thorough quality control so that our customers can use our products with peace of mind. Thank you for your understanding.


Repeatedly starting and stopping normal recording while the constant recording function is set may occasionally cause the camera to become inoperable. In addition, it has been confirmed that phenomena such as “FAN error” display and media access lamp blinking may occur at the same time as the operation becomes impossible.

* This phenomenon does not occur if the constant recording function is not set.

The constant recording function is a function that can be set only when MP4 is selected as the main recording setting, and constantly records images on one SD card without interlocking the REC switch.

“EOS R5C”: Products with firmware version or earlier
