G85 overheating? record time? light sensitivity? stabilization?

I had a major and potentially serious overheating issue on my still very new G80 a few months ago. Not with shooting but the camera locked up while I was reviewing some shots. I couldn’t turn it off or do anything with it.

Probably your camera is just fine, but you newer know. For example thermal expansion may have broken things you won't notice yet.

Sounds like you had a software glitch that put the processor into some kind of a continuous loop lockup that kept the processor running all out. This caused the system to heat up from constant power drain. It doesn't sound like an overheating problem that caused a lockup, but the other way around. Computer systems sometimes have failures like this, either due to a bug in the code, a cosmic ray, or a faulty component.

The first candidates for causing this are the data on SD-card, and the SD-card itself. Camera crash has happened to me a couple of times, but since then I have adopted stricter SD-card policy (no swapping of SD-cards between cameras, formatting card more often). This has not occurred since since

Most electronic components are good up to 85Celsius, much hotter than you could touch. I'm sure nothing got fried. (Sony RX100s get that hot regularly with no problems

And if the electronic components fry, you can try to bake them alive at much higher temperatures.

It is good advice to take out the battery if it locks up, to reset the system.

It is the only thing that can be done.
