Welcome to my Sony A7CII (ILCE-7CM2) memory card guide for 2024. Find out which cards are supported and which are the best to buy for your A7CII.
Which Memory Cards are Compatible?
The Sony A7CII is compatible with UHS-I and UHS-II (SD/SDHC/SDXC) cards in its single memory card slot.
Here’s a quick speed comparison between UHS-I and UHS-II cards.
- UHS-I: theoretical maximum transfer speeds of up to 104MB/s
- UHS-II: theoretical maximum transfer speeds of up to 312MB/s
In-Camera Write Speed Comparison
Since the A7CII has only just launched I’ve not yet had the opportunity to perform my extensive in-camera tests.
Therefore the following results are based on my Sony A7IV In-Camera Tests. As soon as I have the A7CII in my hands these results will be updated.

If you rarely shooting continuous bursts then you might be happy with the much slower UHS-I memory cards.
Again these UHS-I results are based on my Sony A7IV In-Camera Tests for now.
