ture opening.
Remove both the port cap and the aperture cover. Power the camera,
preferably using a powercable so that a battery is not onboard.
Open the eyepiece shutter and direct light into the eyepiece by poin-
ting its opening at a desk lamp or an overhead light source.
Situate the body so that the lens port is angled to face you. Run the
camera at normal speed; the opening of the aperture plate should be
easy to detect. If this is not the case, place a white piece of paper be-
hind the camera in your field of view.
With a loupe, closely inspect the frame area. If the light through the
eyepiece is strong enough, you should be able to see the reflection of
the viewing screen superimposed over the aperture opening when
the camera is running. If this is not the case, adjust the amount of
light through the finder by moving the eyepiece in or out of the
light.
When both the viewing
screen and aperture opening
can be distinguished, check
that the viewing screen image
is properly aligned to the
aperture opening (indicated below in grey).
Regardless of the screen or format, the entire full frame indicated on
all screens, should be centered to the entire aperture opening of the
camera gate.
The tolerance for this alignment is approximately the thickness of a
line of the screen. If the viewing screen does not seem to be aligned
properly, check its seating by pressing against the threaded hole with
your thumb.
• 3. Shifting the Viewfinder
The viewing optics of the camera need to be set to the new optical
center of the shifted viewing screen.
Remove the viewfinder assembly from the camera by removing the
four allen screws and spacer that hold the base of the viewfinder to
