Amongst the best-selling cameras by Sony, the Sony a7III is a full-frame camera that features an interchangeable lens, image sensor, autofocus, and 4K video recording capability. However, if you want to use the camera to its full potential, you’ll need an SD card with it that’s compatible and speedy enough.

In this post, you’ll discover everything you need to know about the Sony a7III SD card – its recommended size, specs, and some reliable SD cards for the camera with their respective prices as of 2022.

So, let’s get started!

Sony a7III – Recommended SD Card Specs


The Sony A7III features two card slots, both of which support up to UHS-II rated SD cards. So, although you can use UHS-I cards with the camera, the UHS-II ones will maximize the camera’s performance, when it comes to read and write speeds.

Recommended Sony a7III SD Card Size

Note that there’s 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 Sony a7III, 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.

Lastly, if you want to shoot extended lengths of 4K videos with the camera, then you’ll definitely need something bigger. I would recommend that you go for minimum 256GB SD cards. To put things into perspective, a 256GB SD card will give you around 5 hours & 5 minutes of 4K/30fps video.

Based on the above info, here’s the summary of the recommended SD card specs for the Sony a7III:

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