We are getting a lot of comments and emails from our users related to the Sony A7 IV heating problem. So, in this article, we will discuss the possible fix for the Sony A7 IV heating issue.
The most common question we get
- If the Sony A7S 3 and Sony A7 4 use the same heat sink unit then why does the A74 camera get overheat quickly?
- I am using Sony A73 camera, never faced overheating issues like I am facing in Sony A74 ?
- My Sony A6400 never gets heated while recording 4k, then why A7 IV get shutoff after 20 min?
Answer: you have to understand that A7 IV does oversample from a 33 MP Sensor / it record oversampled 7k+ file for obtaining highest quality possible. Sony A6400 camera does oversample from a 24MP sensor and manages heat and Sony A73 camera also does the same. And finally, the A7s 3 uses a 12 MP (perfect resolution for 4k video) sensor that doesn’t need to oversample or downsample files. Due to the high-resolution sensor and heat-sink unit of the Sony A7s3 camera the overheating issue is coming, Sony needs to implement a better heat-sink system inside Sony A7 4 camera compared to the A7S3.
Sony A7 IV Overheating Fix
The simple methods that will fix the overheating problem of the Sony A7 IV camera are. Keep the display screen away from the camera body, it helps to dissipate heat much faster.
1. Power Setting options (Recommended)
Power Setting option (9) > Auto Power OFF Temp. > High. This is the most important set to increase the threshold of the camera. After selecting High, yes the camera body will get overheated but the camera will keep recording to the maximum extent possible.
2. Sony A7 IV File Format Settings (Recommended)
Select XAVC HS 4K mode, the big reason behind the selection the mode uses H.265 codec for compression, and the file size is approx 2x smaller than the file size we get in H.264 codes. And one of the major advantages we get after selecting this mode we are also getting roughly 2X more recording time with the camera. The only know issue with this model is the frame rates are fixed at 4K 60fps.
3. Movie Settings (Optional)
Once you have selected the XAVC HS 4k mode, Movie Settings > Record Settings > 150M 4:2:0 8bit. If you will select the 8bit recording mode it will create less pressure in the image processor of the camera resulting in less heat generation.
4. Proxy Recording Off (optional)
Keep your proxy Recording Setting off
5. Invest in CF Express Cards (Highly Recommended)
Regular SD Cards tend to generate more heat, better to invest in a CF-express SD card for recording HQ video from Sony A7 IV.
Get these cards asap
Try the recommended methods first, even after that the overheating time isn’t extended compared to earlier settings then also try the optional steps I have recommended in the 3rd, 4th, and 5th points.

Bro, I have bought this camera … but seriously sony messed this time with A7 IV. The camera max recording time limit is 20-3min when the auto power off is set to high
I use α7Ⅳ, but it was over-engineered for me. No wonder that Ⅲ sells.
It sells for professional machines and high amateurs, but I think that the Bic Camera ranking model or III will sell to the general public.
As for IV, it inherits the system such as α1 as a still and has evolved detailed functions, and I am happy that it has high pixels, but I thought that it was for high amateurs including videos, and 7c or zve10 was enough for me. I stretched out and bought IV, so I was agitated to have an aspiration to put on an arm that was commensurate with it.
Including that, professional machines are sold from high amateurs other than Bic Camera, and I think that Sony and others will absorb the demand for video machines for the general public in the future. However, even so, I thought that YouTubers also have many smartphones, and mainly digital cameras are sold aiming for demand higher than high amateurs.
Suck a scam,an expensive camera that overheats very quickly !!!!!!!!!!! I regreate so much buying this crap!>
I disagree with the File format recommendation for Sony a7iv or any other body when it comes to heat. Super high compression means a lot of on board computation, which means a lot of heat. Storing uncompressed data such as S-I takes more space, but generates less heat. Also, flip screen out and open battery door.
