I am pretty sure you can use the CF adapter on any H camera, film or digital. But I'd check with Hasselblad Tech on that just to be safe.
It's a pretty ingenious device. Because the CF lenses are mechanical, there is a lever on the left side that you use to cock the lens after each shot. Hasselblad designed it so you push it up with your left thumb which is actually faster than winding a 500. If you don't cock it, the H camera won't fire, and "Cock The Lens" shows up on the grip LCD.
If you mount any CFE lens the camera automatically knows what lens it is for metering and TTL flash control. With other lenses you use the grip menu to tell the camera which lens is mounted ... the list includes all the lenses and extenders. You do NOT have to stop down meter.
What's really cool is that there is focus confirmation in the viewfinder ... really helpful with those wide angle optics in lower light. You also have full TTL flash control in the camera with any Metz flash and the proper H module. In those ways, it's actually better than the 500 camera.
