On July 5th 2024, Sony reached out to me (Marcus Meissner). Dear Marcus Meissner, Thanks for your efforts to support Sony cameras in gphoto2. In the last years, Sony has put additional focus on supporting integrators who control the camera remotely. We launched Camera remote SDK<https://support.d-imaging.sony.co.jp/app/sdk/en/index.html>, and improved it step by step as well as launched additional products or added features in existing cameras for improved remote control. In addition, we recently decided to officially support low level control of our cameras using USB-PTP protocol, and to release the documentation of Sony PTP commands publicly without Non Disclosure Agreement to allow the open source community to use it easily. Please apply on Camera remote Command<https://support.d-imaging.sony.co.jp/app/cameraremotecommand/en/index.html> if not already done. [also internal contact email offered for questions, and potential loans]
