A very simple solution to a very stupid issue. Make and release an F’ing camera that doesn’t F’ing overheat, or just whack a dirty great big fan on it and make the whole thing even more farcical.
sunnyspeed video to the rescue.
4K video overheating issue is well known for the SONY cameras (such as SONY A7R2, A7S2), the new released A6300 is not an exception.
Depends on the temperature, the A6300 will give you an overheating warning sooner or later. In no time, it will stop recording the 4K videos.
In this video, I will show you a simple and cheap way to make a cooling fan for your SONY camera. I tested this custom made cooling fan, it works very well. I have not seen any overheating problem after using this solution.
