So I had to look for alternatives, and although my lovely Fujifilm X-E3 is still supported in Lightroom standalone, I figured out that, since I am going to leave Lightroom anyway at some point, I better do it now.

And after a summer spent at home hiking my mountains (you can see my wife and me caching sunrise at 8,200 feet here) and editing pictures with a mix of different software, I decided to make Capture One Pro my main software of choice.
In times, where tons of Fujifilm X shooters are migrating to Capture One Pro 12 (including myself) due to a massive 50% discount, I thought to publish a Capture One Pro 12 centric Fujifilm X Trans roundup.
Personally I currently use the last standalone Lightroom version (which still supports my Fujifilm X-E3) and Capture One Pro 12.
