I think this is absolutely amazing. I originally had a Hasselblad H3Dii-39ms and it was a good camera to learn medium format with but I outgrew it and didn't like the ergonomics of it the way I did my Mamiya 645AFD. Which is why I switched to Phase. But Hasselblad makes some absolutely amazing lenses, my favorites were the 120mm macro, 100mm 2.2, 35-90mm, and 300mm. When I looked at cameras to switch to from my Hasselblad, I looked at the S2, but with my trade in I could get 80mp from P1 (which I already had all the lenses for) for the same price as 37mp from Leica. I loved the S but the P1 won on simple math.
I think its absolutely amazing that they came out with an autofocus adapter!! I had often day-dreamed thinking about having an adapter like this for the Hasselblad lenses to any other system, but knew there weren't any adapters that had the electronic contacts etc. I think this is a huge step for Leica expanding their lens range hugely. I may have to take an S2 home with me now and pick up some H lenses!
I don't know if Hasselblad helped with this...I can only see it taking business away from them, and will be shocked if they helped with this adapter personally...
