Sony A7S III announced

My A6000 overheats at 20 minutes in FHD not even 4K, and almost all Sony APS-C line does the same... yet nobody was listening when we complained... now Sony has to listen.
We have a proverb that says : "if your  house is made of glass you don't throw stones at people" Sony is much more widely affected with overheating, now they must take it seriously

The A7S III heats up more, that is why the camera overheated 1st in the same hot situation with a lower bitrate than the R5.
However, the passive cooling Sony is proud of does cool it down faster.

People note that the R5 never feels hot, the battery never feels hot when it does give the overheat warning. The biggest issue is that the camera (at this pre-production state) turns off overheating protection as soon as HMDI recorders/monitors get connected, where it will overheat way sooner in 8K and 4K60, and even in other more "normal" 4K30/24 modes. 
So, the overheat stop looks to be set quite conservative, and the HDMI issue should get a fix in the firmware, and if the camera does heat up, the A7S III's cooling structure is more efficient.

The R5 appears to be an amazing camera, with many aspects beating the Sony A7S III in video (a big higher quality 4K when in HQ mode (oversampling), much better video IBIS, much lower shutter jello and being a great high resolution stills camera. The A7S III does better in really high ISO, of course with a quarter megapixels/half the resolution.

By the way, there probably is a good reason for Sony's weak IBIS with their FF cameras: the corners of the sensor already hide behind the mount without the sensor moving so probably they just can't move further to get better IBIS. The difference between the Sony FF IBIS and IBIS from Fuji, Nikon, Olympus already had been noticed.

A shame we can't have a honest discussion on here about these things, to keep things in perspective. Even pointing out facts like that 4K60 is for slow motion falls on deaf ears, here.
