I have been a Fuji user only relatively recently. My previous system was Canon and the weight was becoming a factor. Sold it all and now a Fuji convert. I have tried to keep it simple and small. XT2 AND XT3 with 16-55, 50-140 plus Samyang 8mm fisheye and 100mm macro. Still making mistakes but hey ho there's always the delete button. I live in Dundee, Scotland and have settled here until my toes point to the sky.
pixel shift would be nice to be able to get higher resolution files but from what i've read the x-trans pixel pattern makes it harder to achieve this compared to the bayer arrangement...
the GFX100 i think does have pixel shift but i'm not sure whether it's bayer or x-trans
That is simply not true. It makes the camera more complicated and more expensive, and the camera usually ends up being a compromise. So there's more to break, more stuff to cool (so the camera is going to be heavier than needed for photography), and more to pay.
I wish Fujifilm would resist the market pressure of the Youtube generation, and focus on creating the most usable and best photo cameras possible.
