Pure speculations: The G4433 - the digital exchangable lens folder

Do you remember this?

That is the GS645, Fuji's pocketable 6x4.5cm rangefinder from the mid 80s. Folding rangefinders are usually single lens cameras. The lenses are usually neither tele nor wide angle designs, but sits at the same distance from the film as their focal length. That way the lenses can be kept very small even if they are of the best possible quality, much like large format lenses. Up until now, digital folders and interchangeable folders have been scarce. It is very hard to create a rangefinder system that is reliable with different lenses. Every lens needs its own cam and they also need different infinity stops.

However, now we have EVF and phase detection pixels on digital sensors. We neither need a proper rangefinder nor a big mirror flapping around to focus. The implications are very interesting. One now could build a folder with swappable lenses or even with an extending telescopic tube like on pocket cameras or the ga645 cameras, only with a mount at the end where one could attach very light and small lenses. And we still could focus them just as well as with an x-t1 or x-e2.

The current rumours says Fujis next camera system will be a digital one with a large 50Mp sensor. That fits perfectly with the excellent dwarfed medium format sensor of the Pentax 645Z. (Dont worry, with its 44x33mm it's still almost twice the size of a full small frame sensor.  Put an xtrans filter on it and put it in a ga- or gs645 package and it will be an excellent sony a7 killer.

Ofcourse I could be totally wrong or the Fuji MF rumour could be nothing but a rumour, but a G4433 fits the specs well and it would be very very Fujiesque.
