I currently have LR 5.7 standalone. I recently purchased two new Sony cameras - a Sony A6000 & a Sony RX100 IV. Looking at the supported camera list it looks like the a6000 needs min. Camera Raw 8.4 and min. Lightroom 5.4. The Sony RX100 IV needs min. Camera Raw 9.1.1 and min Lightroom 6.1.1. Does this mean that I need to upgrade to Lightroom 6 or the Creative Cloud in order to use Raw in LR with the RX100 IV?
Yes, for Sony RX100 IV, you need to either upgrade to Lightroom 6 or you can download Adobe DNG converter to convert raw files into DNG and then, access them in Lightroom.
Thanks for the quick response. I guess I will be downloading the Adobe DNG converter for now.
