Sony A7-III HDMI output disabled when tethered to USB

[leolabs]

I just tried setting this project up, but my Sony A7-III is wrongly recognized as an A7S-III and no controls are available. I've set the camera to be in "PC Control" mode and connected it to my Mac via USB.

Here's the camera report:

Is there a way to fix this or make it work? I'd be glad to help if there's anything I can do :)

For completeness, here are the logs I get when I connect my camera. The camera is stuck in "Connecting...".

I also see that Google Chrome and Google Backup & Sync are trying to access the camera in the logs. Could that be a problem?

[leolabs]

I think I found the culprit. I'm running Micro Snitch in the background to be notified when apps use my webcam or microphone, but it seems to collide with PTP Webcam. Closing Micro Snitch and re-connecting the camera seems to do it.

I got two more errors though:

1. When I connect my camera, I get this message:
2. It seems that the ISO value isn't read correctly. It seems a bit high :D Could this be because my ISO is set to Auto?

[leolabs]

Another issue I'm seeing (but that might be more related to the camera) is that my camera's HDMI output is disabled as soon as I connect it to PTP Webcam. I don't really need the camera's video feed over USB, only the controls, since a capture card has a higher quality.

Is there a way to disable your app's video feed functionality and just use it to control the camera's settings?

[dognotdog]

@leolabs I am not sure what to do about the HDMI feed. PTP Webcam does not do anything special to Sony cameras to change LiveView output, as it's always on, and only initiates the tethering connection to the camera to be able to control the settings.

There's a dpreview thread about other cameras having the same issue, and a thread on the Sony forums about the A7-III, but I can see no clear resolution.

As for the other issues, apparently there was a mixup with the A7-III USB product ID, so that'll be fixed in the next release, as well as the error dialog. I've also added a human readable name for the Auto-ISO value.

Hey @dognotdog,

Thanks for your quick response and thanks for working on this project and making it freely available :)

I've just checked and noticed that my camera's firmware is waaay outdated:

I'll do an update and report back whether that solves the HDMI issue. Maybe the simultaneous output via HDMI and PTP control could be a column in your camera matrix so others can check it as well.

Regarding the other issues, thanks for fixing them. I'm looking forward to the next version!

[dognotdog]

@leolabs did you manage to get things to work?

[leolabs]

I stopped trying after a while, but I see that you've just released a new version. Do you think I should try it again now?

[dognotdog]

@leolabs I haven't done anything to resolve the HDMI issue, as that seems to be a camera feature/bug, but I was wondering if you tried with the updated camera firmware?

[leolabs]

Ah, no, that didn't help, unfortunately :/

I'm still using my HDMI capture card but just left the camera settings on auto while adding more light so I have fewer issues with white balance.

[JMY1000]

Pretty sure the HDMI thing is a camera firmware restriction. Otherwise, my a7 III works great.
