Hi,
And Kodak had APS-H models, using Nikon N90 and F5 and Canon EOS-1N film bodies. I had them all. Even monochrome versions.
However, no one made a digital APS-P (Panoramic, the third form of APS film).....
By the time anything came out of Fuji by way of designed to be APS-C, the APS film standard was already dead and buried. Perhaps they ought to call it their small format to line up with the way they call the GFX large format. Maybe they already do. Fuji happily marches to the beat of their own drum. :)
As far as the 44x33mm sensor being cropped medium format, there is no way around that. Pentax was first to use it in 2010 and they opted to make use of their 645 bodies and lenses.
What I see in regards to Fuji is they locked themselves into that size with their system, so they can't make use of the physically larger 150 MP sensor. Not that I think they need it. 100 MP seems to do just fine. And we don't know what's coming next for that size. Sony has a new fab. Right now, only for industrial uses, but we all know they won't be stopping there.
