Is this for the ZD camera or ZD back? FWIW, the Minolta np-400 battery is identical to the Mamiya PB-401 battery for the ZD back (don't know what the ZD camera uses), and this charger will work: http://www.bhphotovideo.com/c/product/3875...r_100_240v.html
Many thanks for the link Jack, looks like the very item required. I'm puzzled by the price difference between the NP400 at $30 and PB401 at $169 though. Are they the same animal or does the whiff of a rip off scent the air?
As far as I am aware the ZD camera and back use the same battery.
