Best Memory Cards for Canon EOS 5DS & 5DS R

Best SD cards and CF cards for Canon EOS 5DS & 5DS R. Here is our full list of top recommended SD cards and CF cards for Canon EOS 5DS and 5DS R DSLR cameras.

Both Canon EOS 5DS and Canon EOS 5DS R feature a newly-designed 50.6MP resolution 35mm CMOS sensor along with dual Digic 6 processors allows for some of the sharpest images ever captured by a DSLR. The difference between the two cameras is that the 5DS R has a low-pass filter effect cancellation, which effectively improves the sensor’s sensitivity. Both models borrow the advanced programmable auto-ISO sensitivity from the 7D Mark II providing increased control over ISO sensitivity before having to stop down. With its built-in intervalometer, create time-lapses and long exposures to capture everything from an incoming storm to light trails from cars on night-time cityscape. In addition, featuring a 50.6MP full-frame CMOS sensor and dual Digic 6 processors, both Canon 5DS (Amazon, B&H, Adorama) and Canon 5DS R (Amazon, B&H, Adorama) are able to deliver ultra-high resolution images for large-scale printing and extensive, creative cropping and the top-of-the-line image quality and processing speed, and both cameras are capable of fast continuous shooting up to 5 fps, full HD 1080/30p video recording capability and Time Lapse Movie function.

Want to get the best memory cards for the Canon EOS 5DS & 5DS R? In this post, we are going to go through absolutely everything you need to know before buying the best memory card for Canon EOS 5DS and 5DS R.

First off… What kind of memory card do you need?

Before buying a memory card, make sure it complies with your Canon EOS 5DS and 5DS R cameras. This is what Canon EOS 5DS and 5DS R require:

  • Memory Card Slot: Dual Slots – 1x SD/SDHC/SDXC (UHS-I) and 1x CompactFlash (UDMA 7)
  • Memory Card Type: SD Card, CF Card
  • Memory Card Speed: UHS-I SD, UDMA 7 CF
  • Recommended Capacity: 32GB-512GB

So, both Canon EOS 5DS and Canon EOS 5DS R have two memory card slots: 1x SD memory card slot with UHS-I support and 1x CompactFlash memory card slot (UDMA 7 compatible). Dual SD and CF memory card slots allow you to extend your file saving capabilities by permitting overflow recording or in-camera file type separation while shooting.

Why Do You Need a High-Speed Memory Card?

Not every memory card will work well with your Canon EOS 5DS and 5DS R DSLR cameras. If the card is too slow, you may have to wait longer for the buffer to clear or end up with recording errors and loose all your footage. So, buying a fast card is always worth it:

  • Fast write speed provides fast buffer clearing time between burst shots optimizing your shooting experience.
  • Fast read speed can let large files such as 4K video or a bunch of high-resolution images by continuous shooting transfer to PC in seconds.

Reminder: if you plan to shoot videos, stick to 64GB (or larger) cards for the best video codex.
