I went to an awards ceremony yesterday to shoot a few pictures of graduating seniors in a temperature controlled indoor gym. It was about 70F inside and I was sitting with my R5M2 on and not shooting pictures for about 30 minutes, raise the camera up to take my first shot and already at 3 bars on the temperature gauge. This seems absurd to me that an idle camera would run so hot. I have the fan grip for it but do not use it all that often, guess I need to make it a permanent addition after seeing this.
