I have the opportunity to acquire a Phase One H20 digital back for a reasonable price to use with my Rollei 6008, as my first step into medium format digital. Most of my photography is outdoors (landscape).
I note that this back has no viewing screen, but it does have a Firewire/IEEE 1394 interface. Is it possible that the latter interface can be used to connect to a small portable device (preferably smaller than a laptop) out in the field, rather than having to connect to PC located in a studio ? If so, is anyone using the H20 like this and how portable is the solution ?
