The A1 records 8k externaly without overheat, doesnt it?R5 will be the first mirrorless camera that I am aware of to record 8K externally and A1 absolutely overheats recording internally.
Sony even says that.
It is just nowhere near as bad as the R5.
And its not overheating in 4k60 internaly, or am I mistaken?
These are pretty important things, at least in my workfow
