Like I said I am not expert but nice thing with Fuji GFX is that the focus stacking is built in unlike Sony.

My coworker has the GFX100 for a while now. I had been busy with work, home stuff so didn't get a change to test it out. And now I am not sure how long we are stuck indoors. The Fuji GF lenses were already made to handle 100MP fro the start. I am surprised how good corner to corner they are. The system is definitely more money but usage wise it is worth it, if you into landscapes and portraits. The GFX100 is little too big for me as I am getting older now and being handicapped it is harder for me to carry things. My last vacation I couldn't even walk but still took the GFX50s along with Sony A7rIV and for landscapes I honestly preferred to use GFX so much more. This was when I was walking with two crutches and each step hurt. All the buttons are thought through, flip LCD in both directions, pinch/swipe gestures and the list goes on. GFX100 kicks that a couple of notches higher with new digital control dials, much better AF (compared to GFX50 models) and IBIS. I thought I wouldn't like the new dials but shooting more tethered now, I can see why Fuji went that route.
I would of thought he might have tried the GFX50 after discovering the issue for his kind of shooting with the big brother.
You mentioned your able to shoot portrait and landscape with your GFX50, does it have the same issue with shallow DOF as the GFX100?
Do you have to use the in camera function for image stacking for your landscape, or can you use it like one would with a non medium format camera?
Does the GFX100 also that the in camera function for image stacking?
Any particular reason's you prefer the 50GFX over your A7rIV
