Mamiya RZ67 PRO IID
The P back for Mamiya 645 AFD also supports the
Mamiya RZ67 PRO IID via the 645 AFD adaptor plate
from Mamiya.
The mode selector
on the trigger button
should be turned to the
white dot when used
with the P back.
When the P back is placed on the body
and not in use, the selector should be
set to the orange dot, to avoid draining
the small battery. Even if the P back is
turned off, the battery will drain slowly
if selector is not at the orange dot.
