There are a couple of reports right now of users managing to overcome the overheating limits of the Canon EOS R5 mirrorless camera. Well, sort of. By tricking the camera into thinking the battery slot door is closed when it’s not, people have found a way to reset the timer. But there’s a catch. Your footage is pretty much useless.
The video above by J. Marcus Photography demonstrates the technique, and how he was able to reset the timer using just a piece of tape over the battery door to make the camera think it was still closed. When the overheat warning came on, he removed the battery, reinserted it and magically the overheat warning was gone.
