When faster media matters
Everyday recommendation
V30 SDXC for recording qualities through 200 Mbps.
Demanding recommendation
A quality V30 UHS-II SDXC card meets the camera's listed 200 Mbps tier; faster V60/V90 media can improve reuse across other bodies and ingest.
Panasonic's S5II card table calls for U3/V30 at recording qualities through 200 Mbps.
Plan the complete workflow
Capacity
Both slots support SD, SDHC, and SDXC up to 512GB in the referenced manual.
Reader
Use a UHS-II SD reader for faster offloads from UHS-II cards.
Three checks worth making
- Do not confuse the S5II with S5IIX external-SSD and higher-bitrate options.
- Both cards must meet the selected mode for redundant recording.
- Check Panasonic's confirmed-media list.
Verify the current requirement
