Do you wonder why your Sony a7III camera overheats sometimes? That makes the two of us. As someone who occasionally feels the camera getting hot, I am curious about the reason behind this phenomenon. So I ended up researching the issue and sharing the information I found below.
The Sony a7III can overheat if you shoot photos and videos continuously without a break. The mirrorless camera has to work harder to process all the data, leading to increased temperature.
Other factors also contribute to the camera overheating, which I will cover below. I will also teach you several ways to prevent this issue and start shooting again.
Why Does The Sony a7III Camera Overheat?
Reports of Sony a7III and other Alpha cameras overheating are quite common. However, this camera is just one of the many models that suffer from overheating issues. So before I get into the prevention tips, I would first like to cover why the Sony a7III tends to warm up.
Continuous Use
The most common reason the Sony a7III overheats is because of continuous shooting and recording.
This mirrorless camera packs powerful features, namely the 10 fps burst mode and 4k video resolution. While the a7III has no trouble delivering exceptional results, it can struggle a bit if it is handling too heavy processes.
Sony did not design the a7III camera to record non-stop footage. So if you are always shooting 4K videos for long periods, the process can take a toll on the camera performance. It ultimately leads to the Sony camera overheating.
Shooting Environment
External factors can also contribute to the increased temperature setting of the Sony a7III camera. For example, shooting under direct sunlight or in areas with hot temperatures can lead to overheating. The lack of ventilation in an indoor shooting environment also causes the camera to warm up.
Live Stream Recording
Recording live stream videos using the Sony a7III causes it to overheat. That is because streaming a live event is quite a heavy process for the camera.
Power consumption may also be high during the live stream, leading to the battery heating up. Once the battery warms up, it can increase the overall temperature of the mirrorless camera.
How To Prevent Sony a7III Overheating Issues?
By now, you understand why the Sony a7III overheats. The next thing to learn is how to keep it from warming up while shooting.
Use A Mini Umbrella
As mentioned, shooting outside under direct sunlight can lead to the Sony a7III overheating. You can use a mini umbrella to protect the camera from the sun. Look for umbrellas with a universal clamp or holder clip, so you can attach them on top of the camera. You can also buy a cold shoe adapter where you can mount the umbrella or any DIY shade, such as a foam board.
You can ultimately keep the camera cool by minimizing the heat that comes into contact with it.
Look For Natural Airflow
Are you shooting indoors away from the sun but still face overheating issues? Try to move the Sony camera to areas with good airflow. Avoid cramped or humid places, such as the basement or the bathroom. If that is not an option, you can also stay close to a fan. Doing so might prevent the camera from overheating quickly.
You can also try pulling out the rear screen from the back of the camera. You can even open the port doors on the side of the Sony a7III. Expect heat to be trapped in these areas. Once you open them up, you promote good airflow and help the heat dissipate faster.
Get A Faster Memory Card
Older memory cards tend to work slower, which leads to constant buffering. The slow performance forces your camera to operate for longer periods. And as stated earlier, extensive use can cause the Sony a7III to overheat.
You can prevent the overheating warning by inserting a newer and faster memory card. It helps the camera process files quicker and allows it to stay idle when it is not writing data.
Swap The Battery
The camera battery can also contribute to the Sony a7III overheating issue. It is among the fastest internal components to heat up because it powers up the entire camera.
To keep heat at bay, try to open the battery door. You can also place a fan beside it to cool down the camera.
If these do not work, you can change the battery. Swap it with an external or dummy battery. Not only does the new battery solve the overheating issue, it can also extend the battery life. It allows you to shoot more hours worth of video footage.
I recommend checking out USB power banks. These external batteries are easy to bring while traveling. They are also compact enough, so they do not take up a lot of space in your bag. Plus, they are versatile and can be used to charge your phone.
Consider Camera Accessories
Another effective way to prevent Sony a7III from overheating is using a battery grip. This camera accessory allows you to hold multiple batteries for extended shooting. At the same time, it moves the hot battery away from the main camera body, ultimately preventing increase in internal temperature.
You can also get another external power source, such as an AC adapter or V-mount battery. It can take off the heat from the Sony camera.
Take Small Breaks
I know this method sounds less than ideal, especially if you fear you might miss the perfect shot. However, if you already tried other ways before, but the a7III still gets warm, consider taking breaks in between shots.
Turn off the camera for a minute or so. Doing this allows the Sony a7III to cool down and increases its total runtime.
You might also want to avoid burst shooting mode if not absolutely necessary. For instance, if you are doing portraits or street images, capture the image once or twice. There is no need to click the shutter button multiple times because it will only cause the camera to work harder. By recording at the right time, you can prevent overheating issues and save time in post processing.
Use An External Device For Livestreams
If you are streaming live, you can connect the camera to another device to reduce the data it must process. The device can be a computer, an external monitor, or an encoder. It can handle other heavy processes, which causes the Sony a7III to overheat. The external device can ultimately decrease the temperature of your Sony camera while live streaming.
Conclusion
The Sony a7III is a powerful camera, but it can occasionally suffer from overheating issues. Major causes of increased temperatures include continuous shooting, ambient temperature, and live streaming.
Fortunately, you can use an umbrella or a fan to cool down the Sony camera. You can also change the battery or storage card and follow the other methods listed above.
