Just treated myself to the Sony A7 III full frame camera but mortified to find it is not supported by my version of Adobe's Lightroom (4.4). Despite spending my life savings on my camera (& lens), I don't have the cash to spend a fortune on Adobe's Cloud Based Lightroom monthly subscription option and cannot find a standalone version to buy that supports the .ARW extension. I've found and tried some free software from Sony but I miss some of the features of my (old version) of Lightroom. Some forum has told me I need Lightroom Classic CC 7.3 but cannot find it available online. Does anyone know where I can get this version of Lightroom - does it exist? Are there some good alternatives?
