I dunno. You can say all of this, but the flip side is that the camera should be overheating.
You’re saying it’s not getting hot, etc. It’s cooling down super fast. Without good heatsinks And it’s a full frame moving tons of data. In a small enclosed body.
you can measure what you want, and get results that seem one way. But just _thinking_ about what is happening without measurements, the camera _should_ be overheating for a time. I don’t think canon is so advanced that they’ve solved a problem that Sony and others haven’t solved.
you’re also making a lot of assumptions. “Canon should have the exif data right Bc reporting temp is easy”. You can’t make any assumptions. Stuff isn’t working right, anything could be broken.
