The camera is not on the list of supported cameras. The workaround is to wait until Lightroom is updated to support the camera. There is a possibility that it could be included in the next update. But that is only a guess. You should have received software from Panasonic that enables you to open those raw files and save them as TIF files. Then those could be imported into Lightroom. Not the perfect solution, but it's something you could use in the interim.
I'll try that. Thank you for the advice!
