This is true. A higher refresh is pretty power hungry. That coupled with 5G would be a big hit on battery life.

Good stuff on there with real reviews
I agree. I thought the video Shane Hurlbut did with the 1Dc was much better, and that camera is 7 years old.
The 8K is really only intended for photographers who want to pull stills from sports or fashion shoots.
Do you even know if the Tilta fan significantly cools the camera?
You would be better suited buying the EOS R.
