Who uses the camera to record Full HD videos, should think of a generously sized memory card, min. 32 GB SDHC, better 64 or 128 GB SDXC.
exFAT file system (instead of FAT32) recommended, because even a single video clip of 30 minutes can be larger than 4 GB. 4 GB is the maximum size up a single file in FAT32, is the limit when it exFAT not. But the other hand you can on your PC to format a SDXC card with FAT32 (Windows with third-party tools) in order to achieve compatibility with non-Microsoft operating systems, then just the limit of 4 GB per file.
Oh yeah ... the camera also has an internal memory. But forget quickly again, he takes on any videos, ranging in high-resolution images on a single screen, only in low resolution to fit more pure. That would be Panasonic then can quite equal pay.
