The Canon EOS R was a bit of placeholder for while until it was technically replaced by the Canon EOS R6 and R5. But it’s still a compelling choice for video and YouTube creators and so you’ll need to know which are the best memory cards for the Canon EOS R.
It may have a huge crop, but this full frame camera from Canon has helped many YouTube creators create incredible video content. So with video in mind this is my recommendation for the best memory cards for the Canon EOS R:

Now that I’ve given you the best two options that should cover most bases for the general user of a Canon EOS R who might mix up their video with a bit or more photo needs.
But you may need a more bespoke recommendation that’s tailored to your specific needs. Perhaps the memory capacity you require has to take into account how you film, or maybe you shoot more photos than a regular video content creator.
A good example is myself, I take a lot of photos for my blog, and then again for my stop motion portions of my video content. I would need to account for this mix of video and photos. For instance I probably would not need a 256GB card.
Either way the Canon EOS R is now an underrated camera choice and at the current price is very tempting:
- 30.3 Megapixel Full frame CMOS Sensor and DIGIC 8 Image processor
- Dual Pixel CMOS AF with 5,655 manually selectable AF points

What Type of Memory Card Does the Canon EOS R Use?
The Canon EOS R has one memory card for SD/SDHC/SDXC cards that support UHS-II speeds. Canon state UHS-I cards are supported but you will find them not adequate to record modes like 4K or the high frame rate mode.
As the Canon EOS R can record 4K video shooting you will need a fast card so that the EOS R can write to the card quick enough to avoid any video issues. Fortunately Canon have supplied a table for the relevant cards and modes:
Although they don’t state it here, I would also recommend choosing a speed class rating of V90 just for that extra reassurance and future proofing.
How Much Video Can You Record to the Canon EOS R
Now that we have established what memory cards are required for the available modes on the Canon EOS R, now we can work out approximately how much content we can write to an SD card so you can match the right card to your needs:

I wouldn’t recommend a 64GB for any of the high bitrate video modes, especially 4K, you’re running into bottle necks within 30 minutes.
It makes no sense having to buy more cards later; it’s better to spend a bit more now for less hassle later. So 128GB and 256GB are the optimum card capacities for video. Both brands above offer SD cards in both capacities.
How to Choose Best Memory Cards for the Canon EOS R
Ok so now you have the best choices of SD cards for your Canon EOS R, what about if you wanted to work it out for yourself?
Let’s take a situation of a corrupt memory card on the job, and someone offers you a selection of spare SD cards. How would you know which one will work, without testing them all out which might not be feasible.
Learning to read the front of a SD card is an invaluable skill that you may be called upon to use when you’re in a pickle. Let’s go over the two requirements Canon say to look for on a SD Card:
Although Canon state you can use UHS-I cards, they recommend UHS-II cards. This is so you can record 4K and the other high bitrate modes without issues.
The best way to work out if a card is a UHS-II card is by the second row of pins on the rear or the card, which is for faster read/write transfer speeds.
Speed Class Rating
The most important variable are the speed class variables that Canon state in their documents.
For 4K All-I the speed class minimum requirement is Class 60 denotes a minimum write speed of 60MB/s.
For 4K IPB a speed class 3 or higher is required, this is denoted by a symbol of a U with a 3 inside. Which indicates a minimum write speed of 30MB/s
I hope this article has supplied with all the information needed to get you the right SD card for your Canon EOS R.
No one wants to get the wrong card that’s too big for your needs, where you could have spent the extra money on other essential gear. Or conversely too small, meaning you’ll have to spend again or work around bottlenecks.
Get the right SD card the first time and you can forget about it and concentrate on the work.
Now you have that sorted, you’ll need a decent SD card reader. I recommend this one:
- Simultaneously read and write on two cards to save yourself the effort of constant unplugging and re-plugging.
- USB 3.0 enables data transfer rates of up to 5Gbps for faster Sync times, backward compatible with USB 2.0/ 1.1.
