SONY a7 III a73 OVERHEATING issue
12

After using the Sony a7 III for half an hour taking a few dozen pictures (no videos) I've noticed the camera was a little bit too warm to the touch, so I decided to test the thermals of the camera by recording 4K video and monitor for overheating.
The overheating warning sign appears after approximately 12 minutes of recording 4K video and after 19 minutes and 55 seconds of recording, the camera shuts down because of overheating (minute 07:30 in the video).
I didn't heard anyoane having overheating problems with this camera until now, so I don't think this is widespread, this is just my experience with the camera.

Maybe others who have this camera want to test it for overheating in 4K video mode to see if this is a problem with the camera or just with my copy.

The room temperature was 23 °C / 73 °F
Auto Pwr OFF Temp. was set to Standard
For the test I was using full-frame recording 4K video 25P 100mbps

You could have cut out over 7 minutes of video and just showed the beginning and end.  When I realized after a few seconds there was no sound, I skipped to the end.

I do have the A7riii and haven't heard anything about it overheating, but I usually don't take video for more than a few minutes at a time so for me it should be a non issue.

I abandoned Sony mirrorless cameras a long time ago due to their overheating issues while shooting video.

No overheating issues with Panasonic MFT cameras though.

this should be in the sony ff mirrorless forum.

it's typical for sony to release a milc with overly conservative heat warnings and behavior, then change the trigger points later in a firmware release.

for example, with the a9: https://www.dpreview.com/news/4228347869/new-sony-alpha-a9-firmware-fixes-overheating-warning

I could have cut out some parts from the video, but I wanted to show the whole video, so there's no reason to doubt it.

Everyone has different needs. This doesn't change the fact that this camera shouldn't have any overheating problems, but I think this is an isolated case.

Jealous of you guys who have received your bodies already... for whatever reason they aren't shipping them until April 10th in the US.

Now recording, 4k 25p, 22°C. Display away from body, as in your video. Body just laying on a table.

10min: Body only slightly warm, hard to notice

20min: temperature behind display 36°C, the rest stays cool.

30min: temperature behind display 38°C, no sign of overheating.

Would suggest you send/bring back your camera - that's not normal for sure!

Edit: btw, I also had Auto PWR off at low, no problem at room temperature.

No screen dimming.

The problem is that even my a6300 in the same room temperature can record almost 45 minutes. This newer Sony cameras, from what I've read, should have solved the overheating problem or at least have a much improved recording time without overheating.

others seem fine though

try to do a few more tests to see if you got a bad copy

From the tests that others have made and from what I've heard from reviews, I am now convinced that I have a defective unit.

I contacted Sony support and now I am waiting for their response.

If any owner of the A7iii is in possession of an HLG-capable TV, I'd appreciate it if you could check to see if the camera can output an HLG video to your TV via the A7iii's HDMI output.

Why not return the camera to where you bought it for an exchange? Wouldn't they be much quicker?

I am from Romania and I bought the camera from Germany, so, if I return it for an exchange, I would have to pay for shipping both ways and even if I do this, no one seems to have the camera in stock now or in the near future.

Depending on the response I will receive from Sony support, I will decide what to do.

Sorry, I don't believe you. The camera 'was a little bit warm to the touch' after shooting 24/36 pictures (a few dozen). Where was it warm?

so I decided to test the thermals of the camera by recording 4K video and monitor for overheating.
The overheating warning sign appears after approximately 12 minutes of recording 4K video and after 19 minutes and 55 seconds of recording, the camera shuts down because of overheating (minute 07:30 in the video).

Why haven't you linked to the whole video 19 minute video then? What use is the last seven minutes?

If you're posting the video as proof you need to show the whole thing, from start to finish.

I didn't heard anyoane having overheating problems with this camera until now,

Yeah, no me neither. Here's a link to an A7III test by Max Yureyev, who has done a lot of overheating tests with Sony cameras shooting video. He couldn't get it to overheat. Go to 14.11 in.

He shot it for an hour and a half and didn't even get the high temp. warning. Standard mode IBIS on. He says the camera wasn't hot to the touch.
