Best SD Memory Cards for Canon 6D Mark II

Updated: May 19, 2021

Canon 6D Mark II was released in 2017 and represents the company’s affordable full-frame option. If you don’t need features that the pricier 5D Mark IV offers, it makes perfect sense to save quite a bit of money and get the 6D Mark II. So let’s take a look at some of the best memory cards for Canon 6D Mark II.


I should start by saying that Canon 6D Mark II features one SD card slot that supports UHS-I memory cards. Of course, the UHS-II cards will work too, but you won’t be getting the extra increase in speed.

The camera can shoot 6.5 up to frames per second and can record 1080p video at up to 60 fps, so UHS-I cards will definitely be enough. However, if you plan on upgrading to a newer camera in the future, I might suggest that you get a UHS-II card now and future-proof your purchase. Here are two of the best SD cards for Canon EOS 6D Mark II.

UHS-I Cards:

After 15 years using SanDisk SD Cards I’ve never yet experienced a card failure and here's why. With a history dating back over 32 years, and being the third-largest company in the world for memory (after Samsung and Toshiba), you know this is going to be a robust SD card.

For over ten years, the SanDisk Extreme has been a favourite with photographers and filmmakers for its speed and reliability—and this latest incarnation appears that it will remain as successful.

Our SD card is more than just a tool – it’s a vital record of your memories.

These powerful storage units pack in an immense amount of tech into a surprisingly small area. So, you need a storage device that’s going to be durable, otherwise, you could lose those crucial recordings of your adventures.

You also have to consider that, often, you won’t be using your memory card in the safety of your home. You could be at a sporting event, at the beach, or halfway up a mountain. And, you may also find yourself swapping cards outdoors, exposing your SD card to the elements.

Reassuringly, both the SanDisk Extreme and Extreme Pro is X-ray, water and shock-proof. They have a vast operating temperature range of -13 degrees to +185 degrees Fahrenheit meaning you’re much more likely to expire before your memory card!


Canon 6D Mark II remains one of the most affordable ways to get a camera with a full-frame sensor and believe me it’s a fantastic camera both for enthusiasts who are willing to spend some extra money as well as professionals. As for the SD cards, if you can afford to get a UHS-II card, I suggest you do that but keep in mind that you won’t get any benefits over the UHS-I cards with the 6D Mark II (except the fact that you can offload the data much faster to your computer).
