Exactly. The adapter in this set up uses the Hasselblad lens' leaf shutter. So synchronising to the back is required.
!? so you don't use the CFV-50c II electronic shutter? it's like using the back with 907x+"native" XCD lens? (or you have to use it, set it to a value slower than lens shutter and let the cambo start the leaf-shutter at the right time!?)
(btw then why couldn't hasselblad provide an adapter that fully uses V lenses including their shutter, like they did on the H system with CF adapter, if even another brand could)
and obviously
live view is possible?
and how do you re-cock the lens shutter?
... OK I see it
in this page it's on "WRS-HVSA" adapter itself
I see on
this Cambo page :
As the shutter inside the lens can be activated and released, this adapter can be used with virtually any digital back that can be synced by means of the flash contact. This includes Hasselblad's new CFV II 50C model.
But I still don't fully understand ... (except that I probably need that!

)
And how expensive is this beautiful "toy"?
(I mean WRC-400 + WRS-HVSA + SLW-80 + WRC-H61(grip) =>
WRC-HVSA kit)
... OK 3500$ (in this
digitalback.com page )
And how one would get that in Switzerland?
