It’s fair to say that the release of Canon’s EOS R5 8K capable mirrorless camera was, shall we say, controversial. Despite the 8K abilities of the camera being decidedly groundbreaking it was the thermal handling of dealing of the immense processing and heat off the sensor that got the headlines.

In short the camera only allowed for limited recording times and then demanded an equally long cool down period before it could be used again. Not ideal for many different types of production I think you’ll agree.

It’s important to note that new technology like this often comes with caveats. However Canon has been working behind the scenes to improve the performance of the camera, and it has now manifested itself in firmware version 1.1.0.

The full list of improvements is as follows,

1. Useful messaging is now displayed when [HDMI display: Camera+External monitor] and [Overheat control: on] settings are enabled.
2. When using certain RF lenses for movie shooting, the in-lens image stabilization mechanism has been improved.
3. Fixes a phenomenon in which the "Slow Synchro" setting screen is not accurately displayed, when the language is set to English.
4. Fixes a typo displayed on the communication setting screen, when the language is set to Korean.
5. Connectivity during FTP transmission has been improved.
6. Fixes a phenomenon, in which the card access time may take longer, when using certain CFexpress cards.
7. Temperature detection and shooting time control in video shooting have been improved. In addition, the total shooting time when the short-time recording and power-on/off are performed repeatedly at room temperature is improved.
8. The phenomenon in which the movie recording time available is not correctly displayed when the Date/Time/Zone is not set has been corrected.
