Mamiya RZ Pro II D internal battery rapidly depletes when a camera back is attached.

Last updated: 06-01-2016


When using a Mamiya RZ Pro II D with a digital-back the internal battery is exhausted faster than when using a film-back. A new battery will last for approximately 3 days before it is exhausted. This happens when a back is attached to the camera body although the camera and back are turned off.


The design of the Mamiya RZ Pro II D camerabody is made in a way where the body continuously uses power from the internal battery when a digital back is attached. (When filmbacks are attached the camera body goes to sleep 20 sec. after no activity.)


You can prevent the internal battery drain by the following methods.
