Best Memory Cards for Canon EOS R

Memory cards are an essential part of any camera and having an incorrect one won’t allow you to use the full potential of your camera.

The Canon EOS R has an SD card that works with SD/SDHC/SDXC memory cards. The EOS R card slot can handle speeds up to UHS-II.

Canon EOS R SD Card Recommendations

If you want to get right to the point these are the best SD cards for the Canon EOS R. The Sony Tough cards with UHS-II speeds will unlock all features of your EOS R. This includes C-Log video shooting and large raw image shooting buffers. If you don’t use video features or take photos rapidly the SanDisk Extreme UHS-I is a great affordable option.

Why Does a Fast Memory Card Matter?

For Photography:

When taking a large number of raw photos in a row your EOS R will need fast write speeds to write the images to your memory card.

Since the EOS R can shoot 8 stills per second this can produce a lot of data quickly. Using a UHS-II card that supports 300 MB/s write speeds will allow you to shoot the entire 47 RAW image buffer to your card without stopping.

Obviously not everyone needs this functionality. If you aren’t shooting sports or any other subject requiring high-speed continuous shutters then using a cheaper memory card that is only UHS-I will work fine.

For Video:

Video shooters know how much storage 4K and C-Log footage can take up. If you want to take advantage of the 10-bit recording and C-Log functionality of the Canon EOS R you’ll need a fast ~300 MB/s UHS-II Card.
