SD and CFexpress memory card information for still image and video recording with Alpha cameras

    Certain Alpha ILCE and all ILME camera models have advanced still image and video recording features that require attention when selecting memory cards. If you currently own memory cards, compare the card specifications of the camera to determine if your cards can be used. If you are purchasing cards then the specifications need to match your still image or video recording and editing needs.

    Choosing the proper memory card


    • Depending on your camera, it will accept SD, SDHC, SDXC, Memory Stick, and CFexpress Type A cards for still image and video recording.
    • For video recording, the video speed class and the video format you want to record determine if your card can be used with the camera or what you need to purchase.
    • The transfer speed refers to the speed of transfer of the images or video from the camera buffer to the memory card.

      Troubleshooting Tips

      • When recording still images at high frame rates, the camera may buffer if the transfer rate of the memory card can't keep up with the transfer from the camera buffer. In this case, review the memory card transfer speed and try a card rated at a higher transfer rate.
      • If you own an SDXC card that has high read/write speeds marked but doesn't have a V60/V90 logo (required), you will need to purchase the proper memory card as the camera doesn't recognize the read/write speeds and an error message will appear:
