If you are wondering about which SD card is most suitable for the Sony a7III, then you are in the right place. Sony a7 III is a brilliant full-frame mirrorless camera that is available at an affordable price and has a bunch of amazing features. However, not every SD card can be inserted into the camera as certain parameters need to be looked into first.
In this post, you will get to know all about the SD card speed recommendations for the Sony a7 III and what are the best SD cards for 4k videos.
Sony a7III SD Card Speed Recommendation for 4k Videos
The Sony a7III camera has two SD card slots. Slot 1 is the faster slot and it works best with UHS-II cards like Sony SF-G Series. UHS-I cards will also work in this slot, but they are not as fast as UHS-II cards. Slot 2 is the slower slot and it works best with UHS-I cards like SanDisk Extreme Pro. The Sony a7III camera only takes SDXC and SDHC memory cards.
You don’t have to use both slots, but there are some advantages to using two cards at the same time:
- Prolonged hours of shooting without changing cards.
- Increased storage.
- Record simultaneously for a mirror backup.
- Split data into two cards based on file type.
If you use two memory cards at the same time, the write speed will be slower than if you just used one card. The Sony a7 III can shoot 4K video with a maximum bitrate of 100Mbps, which is around 12.5 MB/s. This means you don’t need the fastest memory cards for 4k video recording. Just check the Speed Class rating when you buy the card. You can buy any card that has a Class 10, U3 rating, or those rated as V30, V60, and V90. These would be perfect for shooting 4k videos.
The size of the card depends on what the user wants. If you are recording for a little while, then use a 64GB card. If you are taking lots of pictures in a row, use a 128GB card. Do not use bigger cards than that and put the data on different cards instead so that if something goes wrong, you will not lose everything.
Formatting an SD card is important to ensure that the card is compatible with your device and to prevent data corruption. When you format an SD card, it erases all the data on it and sets up a file system that the device can recognize. This helps prevent errors when saving files to the card and ensures that the device can read the card properly. Additionally, formatting can help extend the lifespan of the card and improve its performance. It is recommended to format an SD card when using it for the first time or when switching it between devices. Read more: Guide to SD Card Format for the Sony a7 Camera.
