The Canon EOS R7 features two memory card slots and is compatible with UHS-II SD/SDHC/SDXC cards and also backwards compatible with UHS-I cards.
We have so far tested 22 UHS-II and 7 UHS-I cards in the Canon R7 to see how they actually perform in-camera. This helps us to provide more real-world advice on which cards to buy rather than just relying on label speeds.
Below you'll find a short summary of our top ten results. We'd recommend visiting our Canon R7 Memory Card Speed & Buffer Tests blog post if you'd like to view all of our comprehensive results including the time taken for each card to clear the buffer.
