Reference Manual
When using the P+ back on a Mamiya RZ67 PRO IID, the flash
sync should be connected on the Mamiya lens shutter. The
flash sync connector on the P+ back is for use with Large format
cameras where no digital interface is available.
The Mamiya RZ PRO IID should be used with Short latency.
Default your P+ back is set to Short latency, which means that
the P+ back will respond fast on triggering at the cost of battery
time.
To learn how to setup latency please consult the Menu mode
section.
