Fuji was always a curiosity, but they didn’t have a reasonably-light long lens…until they came out with the 70-300. Only problem is availability. Seems like you can’t find it anywhere, and it’s a long wait to order one. I’d like to see more hands-on reviews from everyday folks before going I would want to go all-in.
If it helps, the only real reason I moved away from them was I couldn't motivate myself to learn Capture One and LR was mangling the images. LR has been made to work now so when I go back to look at the images I wonder why I switched again - this time to Nikon. I have no regrets moving to Nikon, the Z6 (first gen) is a great camera but now looking back at the images I got, I really didnt need to switch systems and I was completely overtaken by the hubbub about the artefacts from lightroom.
What I still miss is the muscle memory of the physical dials and simple things like the countdown on the long exposures and decent weather resistance, then lets not forget the brilliant implementation of timer mode for dialling in long exposures.
There is a lot to like there.
