So more overheating info is out in case anyone needs to factor this into their buying decision that shoots like myself 80%/20% between film/stills. I expected this to be the case with absolutely no vents/fan cooling on the R5. I think this is why the S1H is fan cooled and why Sony recently decided to leak a rumor about "passive cooling with no fans." They all realize there is no way to dissipate that heat without some form of cooling. I had hoped Canon was able to implement some form of passive cooling as well. But the devil is in the details:
You can record for this long before you need to shut the camera off to cool down:
8K 20mins
4K60 35mins
4K Oversampled 30mins
Camera still has a 29:59min recording limit and will need to press record again after each 29:59 segment.
Once overheated, you need to shut down the camera 10 mins to gain another 3 mins in 8K or shut down the camera 10mins to gain another 10mins in 4K60.
There is an overheat control in the camera that allows the screen not be updated frequently or something to that affect which may help the above limits slightly.
Apparently 4K60 can run longer as it is pixel binned and not oversampled. I think you can perhaps shoot in crop mode and not run into overheating issues.
I had high hopes for this. Overheating in 8K is ok, as I can live with that, but it is in other modes as well. I was about to pre-order this, but this is a dealbreaker for myself. This won't work for shoot docs, and events/weddings. Cumulatively speaking, if I shoot a bunch of 4K uncropped, and then a few long segments cropped, etc. will I still bounce off the overheat shutdown limit? I'm also not sure why there is still a 29:59 limit on this body. Many other manufacturer's recent bodies no longer have this limit.
