Nope, I would not recommend the H2F with anything other than a CF back. Maybe other backs will work with a sync cable. Sofar I have not heard from anyone they have done so, even if it is possible it will be a pain in the b*tt. Maybe Hasselblad will open up the H in the future. I don't know. It does seem to be a good move at this stage. Nobody knows but at this moment your options in this area are limited to a few.
