dIt there was a manufacturing issue they wouldn’t need to issue the Overheat timings advisory and have a menu feature which you enable to protect against overheating, no?
second there was a YT video showing the Canon and Sony overheating in Florida - the guy had a temp sensor which could read the heat from the bodies as they started to record. Iirc, around 120 to 130 degrees constant, with the Panasonic being lower by about 10 degrees. It may simply be the Sony sensor can handle the heat and the Canon one can’t for the same period. Whether 12MP has a bearing on that I don’t know. Presume the same with the Panasonic (to the Canon) and hence why they designed a fan in theirs. Maybe Sony needed 5 years to design a solution which could dissipate the heat / take the heat better / didn’t generate as much heat. Even with IBIS which apparently causes challenges.
My best guess is either they’re taking design from a 1Dx / R1 body and modifying it for the R5/R6 along with firmware changes, or they’ve had a lightbulb moment. Combined they think they can mitigate it to a point, but as you suggest, a complete fix? Not in this generation. I think 8K isn’t really the issue for them - as in, maybe a 1.5x the time would be good enough. I think most concern comes from the 4K modes shutting off. If they can prolong that in the HQ and 120fps without lowering quality to over an hour and offer a gizmo which can cool it quicker (maybe the lens mount cooler but designed just to cool it, not always active), then that might be enough.
Alas it does mean that stills shooters have to wait...
have you seen a photo where videographer was trying to bring R5 temperature down with a massive leaf blower? it didn’t help Much apparently.We'll see. We know already that an external fan will work. Canon ex[
Astrologist have used external DSLR cooling for over a decade.
We already know that an external fan will work. It most often does, Regardless of the interior design of the camera. It's done all the time in the advvent of loss of air conditioning in electronic equipment rooms. The first thing we do is bring in large fans. Most often we can keep entire buildings with racks of equipment cooled for days. Cool that camera body with a fan/blower or the like an one can keep the temps down. I will record my device temps and setting when it arrives today, and proceed with designing my own supplemental cooling until the Tilta, SmallRig, or Canon devices are available. Not are difficult task.
