I don't see this mentioned in previous ZD threads. The ZD back's user manual is silent on this also...
Does anyone know, what's the purpose of the recessed vertical strip of 12 electronic contacts on the ZD back?
There are no corresponding contacts on the 645AFD series bodies.
There are no corresponding contacts on the RZ67 ProIID ZD adapter (HX701).
There is a corresponding protrusion with 2 (not 12!) contacts on the RB67 ZD adapter (HX702), and on the 4x5 ZD adapter (HX401).
Hmm...this might be a wake-up thing, but since the 645AFD and ProIID/HX701 wake the back up through the usual horizontal contacts, and since the RB67 and 4x5 adapters also have these horizontal contacts and their own built-in power source, why are the 2 vertical contacts also needed?
Related question - has anyone managed to use any digital back other than the ZD
on the RB67, using the HX702
adapter directly (no lens-to-back cables)? In particular, I'm thinking of the Phase One backs that need a wake-up signal?
