I’ve taken my Fuji GFX100s (and 100ii) all over the world from Peru to Paris. It’s never been a practical choice but im addicted to the quality. Lens wise - the 45mm is the best ‘one lens’. The 35-64 is just too big to wear all day. The 55mm also works well but is a chonk. Conclusion after 25+ trips is that I need to downsize for travel. I’ve started resenting it as it’s too much camera & the heft is… considerable. Leica Q343 looks like the machine for the job, maybe time to sell some lenses
