Best Memory Cards for Sony a7 II

  • by

Looking for the best SD memory cards for Sony a7 II mirrorless camera? Here we picked the top-recommended & fastest SD cards for Sony a7 II.

The Sony a7 II mirrorless camera has a single SD card slot that supports UHS-I SD cards, including SD, SDHC and SDXC cards. Sony decides to stick with USB 2.0 interface (without the USB 3.0 bus speeds), that means the Sony a7 II will have the very limited write speeds at about 32MB/s. In addition, the Sony a7 II doesn’t support 4K video, so expensive UHS-II SD cards will not offer any advantage in terms of speed (burst mode) or video capabilities for Sony a7 II users, although the UHS-II SD cards can also work in Sony a7 II in UHS-I model at the fastest UHS-I write speed.
