I ran a few overheating tests on my A1 and got similar results to cameralabs.

overheat set to standard:
8k30 200M overheats after 20mins. Turnoff and on again get another 10 minutes.

overheat set to high:
8k30 200M camera on a tripod
records 1h15 minutes until battery exhausted and card full
replace battery and card:
records another 1h15mins until battery exhausted.
This is more than enough for me.

4k60 150M camera on tripod
camera shut down with overheat warning after 1h20 mins.

The camera body gets very warm, I'm not sure I would want to hold it for very long.
The user manual warns of low temperature burns.

I wonder if fitting a cage or battery grip would improve heat dissipation further.
