The Canon EOS R8 is a 24.2 megapixel full-frame (35.9 x 23.9 mm) mirrorless camera that features a single memory card slot that supports SD/SDHC/SDXC (UHS-II / UHS-I) cards.
We recommend using SDXC UHS-II memory cards in the R8 to avoid video files being split into 4GB chunks. SDXC cards support capacities of between 64GB-2TB whereas SDHC cards support smaller capacities of between 4-32GB.

FAQs
How many images can be stored on a 64GB card?
The number of images that can be stored on a 64GB memory card in the R8 varies based on the image type that you are recording in. The following values are approximate because file size varies with the scene being shot:
- JPEG L: 7400
- HEIF L: 7200
- RAW: 2340
- CRAW: 4700
- RAW + JPEG L: 1780
- CRAW + JPEG L: 2860
- RAW + HEIF L: 1640
- CRAW + HEIF L: 2520
How many minutes of 4K video can be recorded on a 128GB card?
When recording in 4K with the R8 you can expect the following recording times with a 128GB card:
- 4K UHD (IPB Standard): 25/30fps, 120 Mbps: approx. 2 hr. 21 min.
- 4K UHD (IPB Standard): 50/60fps, 230 Mbps: approx. 1 hr.14 min.
- 4K UHD Time-lapse movies (ALL-I): 25/30fps, 470 Mbps: approx. 36 min.
Is a V90 rated UHS-II SDXC card required for video?
No. A V60 rated card is sufficient for all of the video recording modes that the R8 supports. You can still use a V90 card if you wish.
Are CFexpress Type B cards supported?
No. The Canon R8 only supports SD/SDHC/SDXC (UHS-I / UHS-II) memory cards. CFexpress Type B cards will not physically fit the camera.
What is the difference between UHS-I and UHS-II memory cards?
UHS-II offers much faster speeds (up to 312 MB/s) compared to UHS-I (up to 104 MB/s). This is possible via a second row of pins and two data lanes for simultaneous upstream and downstream data transfer. The extra row of pins are visible on the back of UHS-II cards. Both card types are backward compatible, but a UHS-II card will only operate at UHS-I speeds in a camera that only supports UHS-I cards.
What is the difference between SDHC and SDXC memory cards?
SDHC cards are formatted using the FAT32 file system which is limited to a maximum file size of 4GB. So when recording video clips, the clip will be split every 4 GB but playback with the camera will be seamless. SDXC cards use the exFAT file system which supports a maximum file size of 16 exabytes (EB), so video clips will not be split. SDHC cards support capacities of between 4-32GB and SDXC cards support 64GB-2TB.
