Hello! Im having an issue that I cant figure out. I always shoot RAW with my D850. With my drone I shoot raw as well but they are .DNG instead of .NEF. My issue is that when I put a memory card in to import it wants to import them as DNG. I have been importing from D850 and Drone for a month now with no issues until last night. I popped my SD card in and it would only let me copy the files as DNG. I looked through all the menus and cant figure out where to change it!
As far as workflow goes, I always import from my D850 directly to an external SSD, but with my drone I copy those photos to a folder on my desktop which I then import to lightroom.
