Best SD Memory Cards for Sony A7RIII

Just like the A9 and A7III, the Sony A7RIII features dual SD card slots. One of these slots supports UHS-II memory cards, while the other one is limited to UHS-I speeds. And while you can use UHS-I cards in both slots, if you wish to get full benefits out of this camera, we highly suggest going for at least one speedy UHS-II SD card.

UHS-II cards

While the A7RIII is definitely not camera for sports/action photography, you can actually shoot up to 10fps at 42MP, which is quite impressive. In these cases you’ll see a lot of benefits from owning a UHS-II cards, as the buffer will clear much faster compared to when you’re using slower cards. Here are some of the best UHS-II cards for Sony A7RIII, ranked by write speeds:
