series and functions as a part of the whole camera system. The IQ1 back

interface.

13.2 Mounting IQ1 back on the Phase One 645 AF &
Mamiya 645 AFD Series
Ensure that the camera mirror is up and the shutter is open when no digital
back is attached. When attaching the IQ1 back to the camera body the shutter
will close and the mirror will come down.
1. Place the bottom of the IQ1 back in the locking mechanism.
2. Press the button (circled above left) with your thumb and lever the back
into place.
3. Release the button to lock into position.
Failure to perform this procedure properly can cause an error with the camera
body where the shutter will continuously open and close. If this occurs, remove
the IQ1 back and follow steps 1 to 3 again.
