Having recently taken to using the R5 for video I have become acutely aware of the overheating problem. It's very ,very frustrating when the warning sign comes on after just a few minutes of recording, especially when the relal action has just begun. Do you continue and ignore the warnings or do you stop ?
On an aside I have been impressed with the IQ of a still image taken out of the video clip in camera with no PP whatsoever.
