Difficult to say anything about the last image since we don't know how it should look. What I do notice is some CA here and there, this is absolutely not there when using HC lenses on a DAC enabled system.
Well, it was supposed to look like a swimsuit model!
This is a 100% crop, and you are viewing 1/3 the pixels per inch that it would print- but I still don't see where there is CA. However full aperture, at the edge, it is possible in a high contract situation (esp backlighting as we had here.)
Point was more on detail and sharpness (latter can be fixed, former not)
Anyway, what I have seen of HC lenses is impressive and possibility to do digital APO, well, if you need it...
For arch/interiors, why wouldn't a pro prefer a view camera? You get the movements and the great lenses, with the same back
BTW, can the hasselblad back come off? I thought only H1 and H2.
Anyway, All systems have their price point, and for the most part, commerce is efficient. Arguments that say a Mimayia or canon or Nikon lens are going to perform like a schneider, Zeiss or Hasselblad don't make sense. If they do make such a lens of comparable quality they will capture the market. But as I understand it the sheer cost of lens blanks, and the extra time in forming and the accuracy in positiong and testing all cost money. I am surprised some of the low volume lenses, like the schneider/Rodenstocks are as cheap as they are wil all the hand work assemby and testing.
That said, I have seen carpenders building fine million dollar homes with a $15 hammer, and others building junk with a $50 hammer (of course I am remembering back-they all use power nailers now :-)
I would assume same with photography; once you hit a certain level of performance, and Mamyia lenses mostly do that with a few exceptions noted here, you can get the quality product out you desire.
