The Sony A6700 features a single memory card slot that supports UHS-II SD/SDHC/SDXC memory cards. It's also backwards compatible with the slower UHS-I SD/SDHC/SDXC cards. You can also use microSD memory cards providing an appropriate adaptor is used.
For the best performance we would recommend the faster UHS-II SDXC cards rather than the slower UHS-I cards. SDXC cards are 64GB and larger, this will also ensure that your video files are not broken into 4GB chunks.
