Rollei ended up in an interesting position at the start of the medium format digital revolution. See, Rollei has generally made cameras that are even higher-end than the notationally high-end Hasselblad, giving you a bunch of really nifty features that weren’t available elsewhere. And, instead of developing a 645 system, like Hasselblad’s H-mount, they kept at their 6x6 format, merely offering decent 645 backs for it.
