Could you please share a screenshot of your metadata panel?
Does this happen only with Nikon D7200 files? Or other camera files as well?
Since the last update of LR I have a problem. When import photos, are only part of the metadata is displayed. That Camera model is detected (Nikon D7200) BUT no objective data.
By "objective data" I think you mean "camera lens data"? (In German, "camera lens" is "Kameraobjektiv".) LR CC 2015.5 / 6.5 introduced a bug where the lens information for Nikons and perhaps other cameras is not properly imported. Please add your vote and opinion to the bug report: Lightroom: Lens metadata field missing on import | Photoshop Family Customer Community . Adobe has acknowledged this bug, but adding your vote will make it a little more likely that Adobe will prioritize a fix, and following the topic will notify you of any updates on the issue.
This is a known bug and a resolution is being worked on.
The data is not missing just not being read....
