Finally, I've made my decision and got Fuji X-E3 camera with 23mm f/2 lens.
First impressions: the camera itself is beautiful, very well made, high quality materials are used, camera is quite heavy, and with lens it's quite front-heavy.
Operation is far from what I am used to. Sometimes it's confusing, sometimes counter-intuitive.
Good example is the shutter speed dial: in theory you can set your shutter speed this way, in practice, you can also adjust shutter speed with rear dial, making setting misaligned with each other.
Electronic shutter is a nice feature, making the camera completely silent. It's weird, as you can have the camera set to high speed burst mode, but the camera doesn't emit any sound at all. Nothing.
Viewfinder is decent, although there is a delay when switching between LCD and viewfinder, much longer delay than on my Sony A6000.
Some buttons and their functions are confusing, but that's a matter of getting used to it probably.
The camera is quite heavy, and I'm not sure if I like it.
Having used this camera for a couple of minutes just now, I miss my Ricoh GR II. Now I understand the benefits of having a minimalist camera. Some cameras have just too many features - this is overwhelming, and often unnecessary. A good example is the shutter speed dial - do we really need it? We have two dials in addition to that, which makes the camera highly customizable, but again: do we need that level of customizing the camera? I don't think so.
In most cases, we set the camera and shoot. That's it. If it gets darker, we might change aperture. When we need to freeze motion, we can change shutter speed. ISO can be auto. For some unusual scenes, we might just put a camera still, and use a very long shutter speed, take couple shots, and get back to 'normal' settings. That's all there is.
Still, it was good to have this camera, even if only to make me realize that minimalist, small camera is actually better. That's still a good outcome.
We want to be 'pro' photographers, who understand and use all those manual settings. But in reality, all we need is a simple A or S mode with exposure compensation and auto ISO, and M mode for special cases.
