So if I'm over simplifying it a little bit, for me it's all about the IQ in relation to price point. Technologically everything else is already "good enough" in the current days' camera market. And since we're talking about only minor improvements in IQ when going from roughly 2k (A7III) to 6k (GFX) in price, there's no way I can justify it for myself.
Don't know what shops you are shopping for cameras in but for me the prices are not even close 4K apart, between the A7-iii and the GFX-50r
A7r-iii is €1770 + Tax
GFX 50r is €3464 + tax
Absolutely agree on value being relevant to self need though, get the best fit for what you can spend, for many that is a 135mm camera is it is good at everything.
It's more forward looking for me and not necessarily where MF is relative to FF right now.
To me MF is currently at the place was where the FF mirrorless was 7 years ago....and with the a7 cameras, the performance improvements in things like AF and even sensor performance improved pretty dramatically between generations, and at a very fast pace. I expect the trajectory of MF cameras to follow a similar trend. I rode the a7 train from the very beginning so I experienced first hand how expensive that can get. Much harder to ride that train though when a ticket at each stop is $6k. Better to jump on the train later in the life cycle.
I also think Sony will jump into the MF space sometime soon as they will have a harder to time differentiating themselves now that Canikon have entered the FF mirrorless space, because their FF have hit a mature point in the upgrade cycles, and because they are already making MF sensors for Pentax/Hasselblad/Fuji.
Don't forget Sony also make the sensors for Phase one, all 150mp of the 54x40mm. I don't know if I fully agree with that 7 year loss, that's comparing a medium format camera to a 135mm one. If you compare the GFX to something like the H6D-50c or the Pentax 645z or the Phase One IQ250 (all the same sensor) you can see how the development of the other things that a camera great have moved on. But if you take it from a camera is a camera point of view then sure I can see that time difference.
