Recommended SD Memory Card Specs for Sony A7III 


The Sony A7III has two places to put memory cards. They both work with UHS-II rated SD cards, which are the best kind to use with this camera. They will help the camera work its best.

SD Card Size recommended for Sony A7III

There is a size limit on both Sony a7III memory card slots. The maximum length each slot can have is 256GB. Therefore, if you’re mirroring, you can have a total of 256GB. On the other hand, if running them separately, then this total goes up to 512GB. Now, let’s talk about the recommended Sony a7III in terms of different use cases.

If you’re just looking to shoot stills with the camera, then I would recommend getting a minimum memory card size of 64GB. This will let you have around 3500 images per SD card if you shoot JPEG. However, for shooting continuous burst shots with your Sony a7III, you should go for 128GB SD cards instead.

I recommend that you get an SD card with a minimum of 256GB. This will give you around 5 hours and 5 minutes of 4k/30fps video.

Summary of the recommended SD card specs for the Sony a7III:

  • Card Type: SD Card
  • Size: Up to 256GB
  • Speed Class Rating: up to UHS-II
