Best Memory Cards for Sony a7 III

The best SD memory cards for the Sony Alpha A7 III. This article will help you find the best and quickest SD cards for your Sony a7 III mirrorless camera.

The new Sony a7 III mirrorless camera comes with two SD memory card slots: Card slot 1 supports ultra-fast UHS-II SD memory cards while Card Slot 2 is compatible with UHS-I memory cards. As we all know, every second matters in photography, so a fast enough memory card is a must for serious photographers. So, if you want to shoot 4K video with the Sony a7 III, a fast UHS-II SD memory card is a must, or you will have to wait longer for the buffer to clear and before you can start taking photos again: Fast write speed provides fast buffer clearing time between burst shots optimizing your shooting experience. Fast read speed can let large files such as 4K video or a bunch of high-resolution images by continuous shooting transfer to PC in seconds.

Reminder: if you plan to shoot videos, stick to 64GB or 128GB (or larger) SDXC cards for the best video codex.
