Lol! You have better English than me. I just understood that he said that warning being there incase of lawsuit from nimble fingers out there.
Also what is remarkable is that this guy said his R5 was in service! And then he babbled something about camera heating up to 120-130 Fahrenheit and cooling downs is hard on the components.
Reading from between the lines. If there is not cooling system inside, it is bad(this is actually also what he said) for these hybrid cameras that shoot 4 or 8 K. I thing I talked before about marketing with numbers...you have 8 But using it frequently might cause your camera to go to service more. Hope that you did not go over time limits maker did say in manual. You might pay that service your self...
it is not that long and these are falling down already.
That said A1 does have cooling system.
And I presume that in next canon there will be one too.
