Lightroom doesn’t recognize raw files from the newest rx100, despite having the latest version of software.
I am using an iMac. I was using the second most recent OS, but I decided to update to Catalina today to see if that made a difference. It still didn't help. I have been using Lightroom CC 2.4.1. I found a workaround that seems to work, but is somewhat tedious. If I open the SD card in Finder, I can select all of the ARW files, select Open With, choose Adobe Photoshop. This will then open Camera Raw 11.4.1. I can select all of the images, click on Save Images, saving them as DNG files, which I can then import into Lightroom.
It's working on my Windows 10 system using LR Desktop 2.4.1. with the Sony DSC-RX100 VII ARW fle downloads available here:
