Best SD Cards for Sony A7III

The A7III has two SD card slots and while one of them supports faster UHS-II cards, you can only use UHS-I cards with the other one. And while you can definitely get just UHS-I cards for this camera, we highly suggest buying at least one UHS-II card. Not only will you get better write speeds while doing continuous shooting, for example, but you’ll also enjoy higher read speeds when transferring data to your computer. These are the best UHS-II and UHS-I SD cards for Sony A7III.

UHS-II Cards:
Sony Tough-G Series SDXC 128GB UHS-II U3 V90 Up to 299 MB/s Up to 300 MB/s
Lexar Professional 2000X 128GB SDXC UHS-II U3 V90 Up to 260 MB/s Up to 300 MB/s
ProGrade Digital 128GB UHS-II U3 V90 Up to 250 MB/s Up to 300 MB/s
UHS-I Cards:
SanDisk Extreme PRO 128GB UHS-I U3 V30 Up to 90 MB/s Up to 170 MB/s
Kingston Canvas Select Plus 128GB UHS-I V30 Up to 80 MB/s Up to 100 MB/s
Transcend 128GB UHS-I U3 Up to 60 MB/s Up to 95 MB/s

Recommended SD Cards for Video on Sony A7III

Sony A7III takes really beautiful 4K video at up to 30 fps, as well as 1080p video at up to 120 fps. That being said, the codecs aren’t particularly demanding (100 Mbit/s or 12.5 MB/s), which means that both UHS-II and UHS-I cards will do the trick, but there’s certainly no need to buy UHS-II cards if you’re only going to shoot videos.


Like we said, many believe that Sony A7III is still one of the best hybrid mirrorless cameras on the market in 2019, and if you want to get the most out of it we suggest buying at least one UHS-II card for the slot that supports it, while you can get one or more UHS-I cards for the other slot, which you can use for backups, for example. We hope this guide helped you chose the right SD card for your Sony A7III. Happy shooting!
