Sony A7SII overheats in 4k mode and shutsdown

I had a shooting last Friday in which we used a sony a7s and my Sony a7sII.
I had a cannon 24-70mm lens with the metabones IV latest firmware update.
We were under direct sun at about 10:00am, and i was to record at 4K.

After shooting 3 or 4 test shots of about a minute each, we started the shooting.
8 minutes later the overheat icon appeared and a couple of minutes later ( in the middle of shooting ) the camera shut down!!

After 15 minutes we tried once more and 3 minutes later it stopped again. 15 minutes later
I decided it to record at HD 25 fps and started shooting again and the show went on till the afternoon that we were able to shoot normally.

During all this the A7s ( the other camera ) was under the sun with absolutely no problem

( all this was performed in front of clients and you can imagine the embarassment...!!!)

 

Anyone faced this issue?

Sorry to hear that Thanassi, this is not very common with A7sII/A7rii after the recent firmware update. 

There are few things that you can try to see if you can replicate the problem:

1. Try with another fast card formated in camera (SDXC UHSII, > 64GB). 

2. Check that dual rec is off. 

3. Athens shouldn't be that humid right now but try another less humid location ?.

I can't think of something else, but if these don't work then I imagine it might be a faulty camera. 

Few things that can help:

1. Pull the screen out.

2. Reduce the bitrate to 60Mbps
