I visited the Three Stage event and got to use the H4D40 for awhile and loved it! After I shot, Hassy USA gave me a thumb drive with 4 images on it and Phocus.
I really like the tools and layout. My question for you MF-D pros here, is do you or can you use Phocus for more than just Hasselblad produced images? I mainly shoot Nikon RAW (NEF).... well... until I can make the move to the dark side
