THE Canon EOS R5 a professional camera capable of shooting in 8K format RAW and 4K in 60fps that costs less than $ 4,000. it is a heavy value, but for the segment this model has been considered as having a good price for the resources it offers. So, of course, there would be a complicated downside just waiting to appear. And it seems that in this case, the overheating.

The video above by Max Yuryev, specialist in content and review of cameras and other filming devices. Yuryev found in his own EOS R5 manual his Achilles heel from overheating. According to official information, shooting in 8K in RAW or HEVC (H.265) format will cause the camera to overheat with just 20 minutes of footage. Using the 4K format at 60fps offers a few more minutes, but not too many – the camera overheats after 35 minutes.

When the EOS R5 overheats it turns off and it is impossible to continue filming. And the cooling time is the real problem of overheating of these models. If you let the camera cool for 20 minutes, you will gain just 8 more minutes of footage at 8K, for example. These are the estimates that Canon offers in the manual, as shown in the table below:

The numbers are especially complicated for those who really want to make professional use of the camera. If you shoot events, like a wedding for example, it is natural to want to take more than 30 minutes. While the 8K resolution may not be as popular yet, we can now imagine that most customers will ask to shoot at least in 4K.


The cheapest option in the new line presented by Canon offers many features

Another thing that should be taken into account mainly by us Brazilians. These overheating estimates were taken in a controlled environment, with mild temperatures. Imagine filming abroad in the middle of summer in Rio de Janeiro, for example.

Yuryev himself says in the video that he has already placed his order for a Canon EOS R5, so he must perform some tests to further discuss the overheating soon. The way to wait and keep an eye on.
