The Sony A7R VI is a 66.8 megapixel full-frame mirrorless camera that features dual memory card slots.
Each memory card slot supports both CFexpress Type A and SD/SDHC/SDXC (UHS-II / UHS-I) memory cards.
For photographers shooting still images a V60 or V90 rated UHS-II card is all you really need. If you shoot action and continuous bursts then a CFexpress Type A card will clear the buffer much faster.
For videographers the card you choose will depend on the video type and bit rate that you wish to shoot in. These are the requirements with proxy off.
- XAVC HS 8K (520 Mbps): CFexpress Type A (VPG200 or higher), SDXC (V90 or higher).
- XAVC HS 4K (280 Mbps): CFexpress Type A (VPG200 or higher), SDXC (V60 or higher).
- XAVC S 4K (280 Mbps): CFexpress Type A (VPG200 or higher), SDXC (V60 or higher).
- XAVC S HD (100 Mbps): CFexpress Type A (VPG200 or higher), SDHC/SDXC (V60 or higher).
- XAVC S-I 4K (600 Mbps): CFexpress Type A (VPG200 or higher), SDXC (V90 or higher).
- XAVC S-I HD (222 Mbps): CFexpress Type A (VPG200 or higher), SDXC (V90 or higher).
With the proxy on or shooting in S&Q any bit rate over 600 Mbps will require a CFexpress Type A (VPG200 or higher).

FAQs
What is the difference between CFexpress Type A 2.0 and 4.0?
The main difference is speed. CFexpress Type A 4.0 cards utilize the PCIe Gen 4 bus which delivers twice the bandwidth (up to 2 GB/s) compared to CFexpress 2.0 Type A cards that utilize the PCIe Gen 3 bus (up to 1 GB/s).
CFexpress Type A 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 A 2.0 speeds. Similarly, a CFexpress A 2.0 card will perform at its peak in a CFexpress 4.0 device.
Are CFexpress Type B cards compatible with the A7R VI?
No. The Sony A7R VI is not compatible with the physically larger CFexpress Type B cards, only CFexpress Type A cards and SD/SDHC/SDXC (UHS-II/UHS-I) cards are supported.
Where can I find the Sony A7R VI specifications?
The Sony A7R VI specifications can be found on Sony's website.
