The Canon EOS C50 is a 32 megapixel full-frame 7K raw cinema camera that features two memory card slots. Slot 1 supports CFexpress Type B cards and slot 2 supports SD/SDHC/SDXC (UHS-II / UHS-I) cards.
Both slots support simultaneous recording even when shooting in raw. All recording options are stored to your inserted CFexpress card, while sub-recording and proxy options record to your inserted SD card.

FAQs
How many minutes of video can be recorded on a 512GB card?
When recording video with the Canon EOS C50 you can expect the following record times with a 512GB memory card:
Cinema RAW Light LT
- FF 3:2 6960 x 4640 976 Mbps approx. 65 Mins
- FF 6960 x 3672 773 Mbps: approx. 81 Mins
Cinema RAW Light ST

Is a VPG400 rated CFexpress Type B card required for video?
We would recommend a CFexpress Type B card that is VPG 400 certified for video recording. This guarantees a minimum sustained write speed of 400 MB/s which is fast enough to support shooting in up to 7K RAW at 2900 Mbps (362.5 MB/s). This is the most demanding video recording option for the EOS C50.
Are CFexpress Type B 4.0 cards compatible with the C50?
Yes, the EOS C50 is compatible with CFexpress 4.0 cards because the 4.0 standard is backward compatible with 2.0. Unfortunately in-camera there is no speed benefit to using a 4.0 card over a 2.0 card because the C50 memory bus does not support the faster 4.0 speeds. Where you will see a benefit is when copying files from your memory card to your computer, with a 4.0 card this can be up to twice as fast compared to a 2.0 card when using a CFexpress 4.0 Type B compatible reader.
What is the difference between CFexpress Type B 2.0 and 4.0?
The main difference is speed. CFexpress Type B 4.0 cards utilize the PCIe Gen 4 bus which delivers twice the bandwidth (up to 4 GB/s) compared to CFexpress 2.0 Type B cards that utilize the PCIe Gen 3 bus (up to 2 GB/s).
CFexpress Type B 4.0 cards are backward compatible with CFexpress 2.0 devices, meaning a 4.0 card will work in a 2.0 camera or reader, but the performance will be limited to CFexpress 2.0 speeds. Similarly, a CFexpress 2.0 card will perform at its peak in a CFexpress 4.0 device.
Are CFexpress Type A cards compatible with the C50?
No. The Canon C50 is not compatible with the physically smaller CFexpress Type A cards, only CFexpress Type B cards are supported in slot 1 and SD/SDHC/SDXC (UHS-II/UHS-I)cards in slot 2.
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.
Where can you find the Canon C50 specifications?
