Originally posted by falconeye Actually, K-7 and 645D have identical electronics. Identical down to the two main processors, buffer memory, 4 channel read-out DACs, HDMI and 921k LCD drivers. The K-7 has additional electronics for audio, the 645D for 2nd SD card.
I believe this is exactly how they did the first Pentax 645. It shared electronics with the 35mm Super-A, the first Pentax camera with the KA mount. Both got the same set of program mode, Tv, Av and manual. It must make sence productionwise and economically, a trick non of the other medium format makers can do since they only make MF systems.
Wonder if any of these new models will get the double SD card ability from the 645D, perhaps with the option to set it up so that video goes to one card and still pictures to the other.
