Does The R5 Overheat In 4k?

Canon’s R5 camera model was released in July 2020 to widespread excitement among photographers and videographers. The camera was touted as a technological breakthrough with many impressive features, including 8K video recording, advanced autofocus, and fast continuous shooting capabilities. However, some users quickly discovered a significant issue with the camera when shooting in 4K resolution: overheating.

In this article, we will examine the issue of the Canon R5 overheating in 4K resolution in greater detail, including what causes the problem, how widespread it is, and whether there are any solutions or workarounds.

What Causes the Overheating?

The Canon R5’s overheating issue is primarily caused by the camera’s powerful processor and the amount of data it generates when recording 4K video. Shooting in 4K resolution requires a significant amount of processing power, so the camera generates a lot of heat. Additionally, the camera’s compact size and lack of an internal fan make it more susceptible to overheating, mainly when shooting in hot or humid environments.

Canon attempted to mitigate the overheating issue by implementing features in the R5’s firmware, such as automatic shutdown and temperature control. These features were designed to prevent the camera from overheating by shutting it down if it detects the temperature is too high. However, these features have not been enough to solve the issue altogether.

How Widespread is the Issue?

The Canon R5’s overheating issue has been widely reported by users and has received significant attention in the photography and videography communities. Many users have reported that the camera can overheat in as little as 15-20 minutes of continuous 4K recording, which can be a significant problem for professionals who need to shoot for more extended periods. Various independent reviewers who have tested the camera in multiple conditions have also confirmed the issue.

While the overheating issue has been widely reported, it is essential to note that not all R5 cameras are affected similarly. The severity of the problem can vary depending on several factors, such as the environment in which the camera is being used and the specific shooting conditions. Some users have reported that they can shoot in 4K for more extended periods without overheating issues, while others have experienced frequent shutdowns.

Are There Any Solutions or Workarounds?

Canon has released several firmware updates for the R5 that are designed to address the overheating issue. The latest firmware update, version 1.3.1, includes several improvements to the camera’s temperature control system and the ability to shoot 4K video for more extended periods before the camera shuts down.

In addition to firmware updates, there are several workarounds that users can try to reduce the risk of overheating. One of the most effective ways to prevent overheating is to avoid shooting in direct sunlight or hot and humid environments. Additionally, using an external monitor or recorder can help reduce the load on the camera’s processor and reduce the risk of overheating.

Some users have also reported success using a technique known as “backyard cooling,” which involves using a fan or other cooling device to blow cool air onto the camera during shooting. While this technique can be effective, it is essential to note that it can add additional weight and complexity to the shooting setup.


In conclusion, the Canon R5’s overheating issue when shooting in 4K resolution has been a significant problem for many users. The point is primarily caused by the camera’s powerful processor and the amount of data it generates when recording 4K video.
