Hasselblad promised, some time ago now, that all products including Ixpress backs, CF as well as H3 would get a speed bump. Both ISO as well as maximum exposure would be doubled.
This is already taking a very long time to materialize and at this moment there has been a very minor FW released that appears to only double the ISO for the H3DII family. Owners of CF, Ixpress or H3D products are not benefitting of the ISO bump.
The longer exposure time is still not here.
I assume, the ISO bump for other back owners as well as the bump in maximum exposure time for every Hasselblad back will be released in the near future like it has been promised on several occasions.
