Hi Kirk,
The folder name on the ingest screen is:
{iptcyear4}/{iptcyear4}-{iptcmonth0}-{iptcday0} Shoot Name
For the Sony files, I suggest that you get any recent Sony A7x model (or even the RX ones, I think) format a card, take a single pic, and ingest. You can take another pic a day later (or adjust the date in the camera).
For the Leica, the files are
ls -al /Volumes/LEICA\ SL/
