The Panasonic LUMIX S1R II is a 44.3 megapixel full-frame mirrorless camera that features dual memory card slots.
Slot 1 is compatible with CFexpress Type B (2.0 / 4.0) up to 2TB in size, and slot 2 is compatible with SD/SDHC/SDXC (UHS-II / UHS-I) cards up to 512GB in size.
For recording in a bitrate of 600 Mbps or less an SDXC V90 memory card is sufficient. For 800 Mbps a CFexpress card is required. For recording in Apple ProRes in anything other than FHD a CFexpress card is also required.
For the best dual slot performance we recommend recording RAW to slot 1 (CFexpress) and JPEG to slot 2 (UHS-II). We also recommend choosing one of the faster SDXC UHS-II V90 cards.

FAQs
What is the maximum size CFexpress Type B card supported by the Panasonic LUMIX S1R II?
The LUMIX S1R II supports CFexpress Type B cards up to 2TB in size.
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.
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 2-32GB and SDXC cards support 64GB-2TB.
Are CFexpress Type A cards compatible with the LUMIX S1R II?
No. The Panasonic LUMIX S1R II 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.
Where can I find the LUMIX S1R II specifications?
The LUMIX S1R II specifications can be found on Panasonic's website.
