When faster media matters
Everyday recommendation
U3/V30 SDXC for video recording and playback.
Demanding recommendation
A U3 UHS-II SD card rated at least 250 MB/s maximum transfer for high-speed frame capture+ or high frame size/rate video.
Nikon recommends the 250 MB/s maximum-transfer tier for high-speed frame capture+ and demanding video settings.
Plan the complete workflow
Capacity
The camera supports SD, SDHC, and SDXC. Choose capacity around video duration and offload frequency.
Reader
Use a UHS-II SD reader to benefit from a faster UHS-II card during ingest.
Three checks worth making
- There is only one card slot.
- Maximum-transfer branding is not the same as guaranteed sustained write speed.
- Reformat cards in camera before use.
Verify the current requirement
