Since updating to the latest release via the Creative Cloud app, newly imported photos are displayed with the lens as 'unknown lens'. The focal length and aperture are correctly displayed but the lens is no longer known. This has started happening for lens and camera combinations that have had no problems in the past. The lens profile in the develop module is selected correctly though.
If I search through the images via the metadata in the library module then the lens is unknown. If I browse photos imported before the update then the lens is recognised.
Any ideas what has gone wrong?
This is a known bug with LR CC 2015.5 / 6.5; see this bug report: Lightroom: Lens metadata field missing on import | Photoshop Family Customer Community. Please add your vote and details about your camera and lens to that bug report, to make it more likely Adobe will prioritize a fix.
