I have a Sony 64GB C10 (SR-64UY) and it partly works with my SJ5000X Elite. With firmware 1.2.1-S cam saves videos EXCEPT 4K and photos to card but you can't see them in playback menu, you must see them through attached cam or at pc directly from sd card. Video Lapse does not record. Firmware 1.2.2 did not auto update from this card. Formatting to FAT32 is not an option for cards greater than 32GB's. Updated to firmware 1.2.2 using 8GB Fat32 SD card. With Sony 64 GB SD card back in cam now records in 4K but Playback sees No Images. And Video Lapse does not record.
The limit of 32gb for FAT32 is only with windows method only, you can install a formatting software, the best is aomei_partition_assistant, it is free

you can format even a 5TB hdd to FAT32
in general if works with your device format it to exFAT, you can store larger than 4GB single file with this format, if that wont work with your device than format it FAT32 with the mentioned software, or linux
