Since the last update for Lightroom 6 the lensinformation is missing in the metadata. What has changed here? The lensinformation is available in the EXIF file.
It's a known bug in CC 2015.5 / 6.5: Lightroom: Lens metadata field missing on import | Photoshop Family Customer Community. Adobe has acknowledged the bug, but it's important that you add your vote and details (e.g. camera model). That will make it (a little) more likely that Adobe will prioritize a fix.
Thanks for the information. I've added my vote and details.
