Feature Compatibility

​
Notes

  1. The earliest versions of PTP date back to 2002 and this was not included in the specification (perhaps not thought of as necessary/useful/possible on the first wave of digital still cameras).
  2. Same as (1) above
  3. Nikon cameras differentiate between “photo mode” and “video mode” with an on-camera hardware switch and do not typically allow capture of (a) videos while in photo mode or (b) photos while in video mode. There are two workarounds we support:
    • You accept this limitation and get full feature support for photo OR video, but not both at the same time, via the hardware switch. This is optimal if you don’t plan to do hybrid shooting within the same session.
    • We allow you to do both at the same time in either switch mode, however when you are capturing in the “wrong” mode” (e.g. you start recording a video while in photo mode), the on-screen display on your camera will be blank and say “Connected to Computer.”
  4. A physical α6700 test found no advertised persistent USB-mode property or USBConnectionModeRequest control. Sending the unadvertised request returned PTP OK but the next reconnect still opened the mode chooser; requesting the advertised OSD image restarted the body into its pre-PTP HID mode. With USB unplugged, setting Setup → USB → USB Connection Mode → Remote Shoot (PC Remote) on the body was then verified to make the next connection enumerate automatically without a prompt. PTP cannot configure the mode that must be selected before the PTP interface exists.
  5. The physical α6700 verified mode-aware focus, still-format, movie-format, and aspect-ratio round trips. White balance was display-only in the tested body mode. The attached lens advertised remote zoom but did not move through either control method, so the API returned an error. Modern α6700 PC Remote uses Sony access authentication and is not implemented by the standard PTP/IP transport. See Sony Wi-Fi WIP. Canon PTP/IP passes simulator tests but EOS 80D first pairing remains physically unverified.
  6. The physical E-PL5 MTP mode publishes battery and date/time but no exposure, focus, or capture property. Darkgrade exposes the capability boundary instead of treating Olympus recognition as proof of control support.
