I seriously doubt that H are more expensive. Lance what's the price of that new DF+ body again? I have found that Hasselblad is offering some great deals. I have already too many cameras, but was tempted by the end of year deals Hasselblad is making on their CPO store. Some camera+back+lens deals under $10k.
btw - I am totally biased so my opinion is only that of myself, so best to demo them both for yourself. In my case, using the DF for a week last year firmed up my opinion as I literally had nothing positive to say for the camera after using it. I like the phase backs and use a Leaf back.
One big factor besides the camera (and lens choice) is the software, Phocus and Capture One, as that is part of the equation. I use both regularly as I still feel they are better than LR4 and while I get around in both ok, I think C1 is easier.
Yes the regular prices between the H4x (with trade in Body) and DF+ Body only are similar:
H4x Body Only $5,695 (requires trade in of H1/H2 body and you need a VF)
So lets say you do not owen a H1/H2 to trade average cost to purchase a used on w/ VF is $1500
Total outlay for H4X body: $7,195
Phase One DF+ Body only: $5990
Phase One DF+ Body / 80mm LS Lens when purchased with a Refurbished System (during winter Promo ) $3500
Phase One DF+ Body / 80mm LS Lens when purchased with a new or upgrade/trade in $4,000 to $5000
So the Phase One is priced more attractive in all scenarios.
I think if we look at the bundled systems H4D 31,40,50,60 the H4D body you get is probably in the same range as the Phase One DF+;s,
but these bodies cannot be used with anything besides that particular back.
We do have clients who do prefer the H4x and we find them an H1/H2 to trade in . They do not mind paying a premium because they like that system.
So it comes back to you do have options when you are using a MamiyaLeaf or PhaseOne Digital Back.
