it is simply a joke...they did not even upgrade the back...leaf, phase and sinar all have backs that shoot faster, to higher asa and with more mature software (without color problems)...all their backs were a little step up from the imacon backs anyway...and they all improved them even more...better screen, faster shooting, even higher asa....it really looks like the only R&D that went into the H3D was to make it propriatory...great..a big step in the right direction...
