I recently bought a Lumix Panasonic DMC-ZS50. When I first imported to LR, I had no problem, but now i get the messaged that this file is not recognized by the raw support program in LR. Any ideas?
Your camera was first supported in Lightroom 6.0. There will be no more updates to Lightroom 5 that will provide support for your camera. You will either have to upgrade to Lightroom 6, or download and use the free DNG converter to create DNG copies that you can use with Lightroom 5.
