I went to my photo dealer to check out systems.
The Sony is great with a lens like the 1.8/55mm.
But:
1) 35mm and 90mm are huge & heavy although I hear IQ is top notch
2) I still cannot befriend the EVF. This might be due to all the clutter switched on
in the demo cameras in the shop. I like a clean view on my subject with some
nevessary info devently placed. An OVF like EVF so to say.
Typically, you can customize what you see in the EVF. I have everything but the histogram turned on in my EVFs. When I'm shooting, I mentally make them visible or invisible per my needs.
I am very intrigued with the Sony's. But I also fundamentally believe that I need to use my equipment until I harmonize with camera and lenses to a point where the equipment is an extension of my eyes and hands. To a point where adjustments are done in an automatic ... semiconscious fashion. I'm not there yet with my Fuji's and I'm reluctant to add a completely new camera, that would dilute my time behind the Fuji EVF, until I feel that I have harmonized with my existing equipment.
