The Panasonic Lumix DC-FZ82D features one memory card slot and is compatible with UHS-I (SD/SDHC/SDXC) cards. The DC-FZ82D is sold as the DC-FZ80D in the Americas and FZ85D in Japan.
If you wish to shoot 4K 30fps video at 100Mbps then you'll require a memory card that is rated V30 / U3 for video.
We would also recommend going with an SDXC card which are 64GB and larger, this will avoid the video files being split into 4GB chunks.
