The RZ is a great camera, but The real limitation of shooting digital with it is the 50% crop.
You lose most of the magic of the 110 2.8, but most of all the viewfinders are optimized for 6x7 not a crop sensor.
You would think that Phase Mamiya would make a better viewfinder with a magnification that is appropriate for the precision
required due to the higher definition crammed into smaller sensors that the original 6x7 film.
It seems that the MF camera manufactures have been taken over by scanner makers or something.
Using the RZ prism was already a stretch with 6x7 film....
Hasselblad used to make a moving high magnification loup, but dumped that..
Fuji in my opinion got the viewfinders right.
Very large rear elements and multiple prisms as well as a mobile high magnification loup.
Before packing up the camera in the studio today I took a quick video of the loup.Fuji loup video
The loup moves around without touching the focusing screen and It opens up to view the whole screen including beyond the composition.
