I guess most members here don't know it, but if you want a "state-of-the art" modern, sophisticated medium format SLR for both 4,5x6 and 6x6 format from new
production, you can get the Hy6 Mod.2, produced by DW Photo (former DHW = former Franke&Heidecke). Despite the insolvency of first F&H, and the successor company DHW, the current successor company DW Photo is continuing the production of the Hy6 Mod.2 medium format SLR and lenses.
Another option are the current Hasselblad H5 and H6 cameras with the dedicated film back.
Hasselblad brought the film compatibility back some years ago because of customer demand.
