Sony A7S III announced
#11
The Canon EOS R5 can do two things to get to 4K30, the Sony A7S III does one thing.
The R5 can do "low quality" 4K30/60/120, going from 8K to 4K with pixel binning. This results in a slightly lower quality than you get with the A7S III with its normal 4K resolution.
The R5 can do "high quality" 4K30, going from 8K to 4K via oversampling. This results in a slightly higher quality than you get with the A7S III. The oversampling is the most heat producing mode.
With 4K60 and 4K120, the A7 III has a slight advantage.

The R5 has a higher bitrate, which results in a bit more detail too.

The R5 has a lot better IBIS for video, and a lot less shutter lag jello. And of course the smoother DPAF. It also offers both UHD and DCI 4K/8K, and the superior to work with C-log over Sony S-log2/3.

Both cameras have advantages over the other, with the R5 obviously having a much higher resolution, and the A7S III one to two stops better noise at pixel level at really high ISO settings. If one for whatever reason tends to shoot 4K video for half an hour long takes, the A7S III has a slightly better quality because the R5 "HQ" oversampling can overheat in 30 mins. For vlogging kinda stuff, the R5 with its much better IBIS and smooth AF has the advantage.
As stills camera, only if you need high ISO low light performance and don't need higher than 12mp, the A7S III is a better choice.

 OTH ...... the A7SIII had only one 4K mode that overheated eventually (nearly an hour) ...all the other modes could record continuously well over the the R5's 29min limit... there is no comparison here ....... the A7SIII basically doesn't overheat and has no limit in record time.

Remember don't shoot the messenger !!
If it is warm enough, the Sony's new passive cooling can't lose the heat to the war outside, making the Sony overheat before the Canon. The Panasonic with its fan did best in warm weather, and the Fuji worst.

Which "war" are you talking about BC ??..... there's been so many !!

The war of energy, Dave... Also known as "warmth" without the "typo / spell check" going on.
