A DSLR (Nikon D810) as a digital back on the Linhof Technika. A medium-format mirrorless camera would make a better combo because of the shorter flange-focal distance and the larger sensor.
I wouldn’t comment on product announcement unless the product is exceptionally interesting, or as the teaser said, a game changer. However, those words have been (ab)used before, in particular in the mirrorless* world, and have eventually left something to be desired.
For everyone who missed it: Hasselblad have announced a 50 MP medium format** (44×33 mm) mirrorless camera with a 2.36 MP electronic viewfinder (EVF). There also will be a new lens line with leaf shutters, for a large range of shutter speeds (60 minutes to 1/2000 seconds) and with full flash synchronization to boot. Rumors had it for Sony and Fuji for a while and I would not be surprised to see a similar offering by Pentax; possibly at Photokina in September (my flight is booked).
*They really should come up with a new name for those cameras, on the same footing that we are not driving horseless coaches.
**Well, not quite to medium-format film standards ranging from 60×45 to 60×90 and even 60×170 panoramic.
