Import von Fotos von Sony Alpha 4

So, your Sony has 1-5 stars, LrC has 0-5 stars. That does not match.

In the back of my mind is a earlier posting, not necessarily Sony, but a difference in available rating led to LrC not supporting the in camera rating. This may have been a issue between another app being used to cull photos and LrC after that app was used to rate photos pre import. Issue is a difference in standard used.

Also, in what metadata field does the Sony store the star rating in vs where LrC thinks they should be?

Does your camera have two card slots? Are you using both slots? If so, did the star rating get saved to just the photos on one slot, likely the primary slot? Might not apply to Sony, appears it can apply to Canon.

In Lightroom Classic Library Module you can select what Metadata is displayed in the Right side panel.

 See the screen capture.

Hopefully another Sony user could explain how they deal with that setting.
