Thanks for this information. I’m going to add this to the meetup archive document that I sent out earlier.
I noticed that you opened an issue on the sequoia-ptpy GitHub repo to try and get PTP working with the RICOH THETA Z1.
Have you evaluated the discussion on using gphoto2 Python bindings to talk to the camera using PTP?
Although the topic title says Mac, one of the guys is using ROS, one guy is using Raspian, another person is using Mac and I’m using Ubuntu. However, I’m having some problems right now using it.
As @mhenrie has provided a working code example, and @NaokiSato102 is working on extending it (last he posted), it might be faster to try the Python gphoto2. mhenrie is using his code with a Z1.
I’m planning to test this myself too. If you’ve already looked at gphoto2 Python module and it doesn’t do what you want it to, I’m going to look at PTPy.
