Introduction
3. General Description
System Overview
The system comprises the following components:
• The Singleframe Hand Control Unit SFHC-1 ➪ photo,
which facilitates setting all important parameters for
singleframe shots.
• The Integrated Capping Shutter (ICS), which ensures that
the camera is light-tight around the mirror shutter for a
period of approx. one hour for taking singleframe shots.
• The Singleframe Film Recognition Module ➪ photo,
which is used instead of the standard film recognition
module or the time code module to reduce the curvature
of the film loop.
• The Singleframe Software, which controls all singleframe
functions in the ARRIFLEX 435.
• The Slide-In Mask ➪ photo and the ICS-Guide ➪ photo
to modify the film gate.
• A light-tight cover ➪ photo for the pull-down claw
slits and the register-pin holes in the film gate.

4. Modifying the ARRIFLEX 435
for Singleframe Takes
First, check that a 26-pin socket is visible on the right lower
side of the camera, as this is necessary for singleframe takes.
If there is no socket, the camera must be modified by an
authorised ARRI service center.
4.1 General
Due to the design of mirror-reflex film cameras, stray light
may pass around the mirror shutter onto the film when the
camera is not running. For normal film shots this is not a
problem, as the affected images fall into the camera run-
up, which is usually not used anyway. On singleframe shots
however, the stray light which during interval time can fall
onto the film around the mirror shutter can affect the quality
of the exposed singleframes.
The ARRI Integrated Capping Shutter covers the film during
the interval time with a thin metal plate. The metal plate is
pushed into the film gate after exposure. Before the next
exposure the plate is removed.

4.2 Preparing
the Film Gate
To accomodate the movement of the pulldown claw during
film-transport, the film gate is designed with vertical slits
on both sides. Furthermore, there are two holes for the
register-pins. These openings must be covered to prevent
stray light from reaching the film.
To enable the shutter plate of the Integrated Capping Shutter
to slide into the film gate, a special guide is inserted into the
film gate in place of the filter holder. The plate then slides
into this ICS-Guide. Due to the form of the ICS-Guide it is
necessary to use special format masks.
• Before removing the film gate turn off the camera’s main
switch and remove the camera from the power supply.
• Turn the knurled knob ➪ photo until its marking
matches that on the movement block.
• Turn the movement locking lever ➪ photo to the “OPEN”
position. This will cause the movement block to swing
away from the film gate.

Installation
• Press the film gate locking lever ➪ photo towards the
magazine throat assembly and push the film gate ➪
photo towards the movement block, pressing lightly
on the lower end of the film gate ➪ photo and paying
attention that the film gate does not hit the movement
block.
• Grasp the film gate by the filter holder ➪ photo and
remove it by pulling upwards.
• Pull the filter holder sideways out of the film gate.
• Press the format mask ➪ photo on its side plate
backwards slightly and pull out of the film gate.
The filter holder and the format mask are held in position
by leaf springs. These leaf springs are each held by two
screws to the film gate.
• Entirely remove the screws holding the lower single
leaf spring, leaving the spring in place.
• Place the cover for the film gate openings over the
fastening holes of the leaf spring. The cover will
deform slightly. Then screw in the cover and the leaf
spring with the two screws.

12
Installation
• Slide the new singleframe format mask sideways into
the film gate ➪ photo (page 11).
• Slide the ICS-Guide ➪ photo (page 11) sideways into
the film gate.
• Check that the film gate and the film gate shaft are
free of dust and dirt.
• Grasp the film gate by the ICS guide and place it from
above onto the film gate shaft.
• Check that the film gate is placed correctly on its shaft.
• Press the lever towards the magazine throat assembly
and flip the film gate back into its correct position.
• Ensure that the lever swings back fully.
Note: The film gate can only be locked if the format
mask and filter holder are correctly inserted.
Swinging the movement block forwards when
the film gate is not correctly in place can cause
damage to the equipment!
4.3 Attaching the
Singleframe Film
Recognition Module
• The Singleframe Film Recognition Module is used
instead of the standard film recognition module or the
time code module to reduce the loop curvature.
On singleframe shots with the standard film end
recognition module or time code module, the
film curvature can cause unfocused images.
The Singleframe Film Recognition Module may
only be used up to max. 120 fps in normal
camera operation, as otherwise the camera may
switch off while running or damage the film.

4.4 Attaching the
Integrated Capping
Shutter
To prevent stray light from falling on the film during the
interval time, the ARRI Integrated Capping Shutter covers the
film with a thin metal plate. After each exposure the metal
plate is pushed into the film gate and removed immediately
before the next exposure. The metal plate slides into the
ICS-Guide attached to the film gate. To ensure optimum
operation, the plate of the Capping Shutter must be aligned
with the ICS-Guide.
• Switch off the main camera switch and remove the
camera from the power supply.
• Open the camera door and remove the two fastening
screws ➪ photo. Any spacers between the hinge and
the camera housing should on inside the housing.
• Attach the Integrated Capping Shutter door by its hinge
to the camera housing and tighten slightly the two screws.
• Position the Integrated Capping Shutter door so that
there is an even gap to the housing and the door can
be correctly opened and closed.
• Tighten the two screws ➪ photo.
• Open the Integrated Capping Shutter door by approx.
30°and turn the door lock to the shut position.

• Press the control knob ➪ photo on the Integrated

the ICS-Guide.
Note: If the knob cannot be turned check if the door
lock is really in the shut position.
Do not use force to push the plate into the ICS-
Guide, as this could damage the plate or the guide.
• Check that the plate can be pushed into the ICS-Guide
easily and without catching. The height of the plate can
be set on the side of the ICS with the hex key ➪ photo.
Note: If the height of the plate is correctly set but it still
catches when being pushed in, the positioning
of the entire ICS door on the camera should be
re-checked.
• Check again that the plate slides into the ICS-Guide
easily and without catching.

door. Close and lock the ICS door.
To prevent inadvertent opening of the camera
door, it can only be opened when the Integrated
Capping Shutter is open.
• Press the control knob of the Integrated Capping Shutter
and turn. The plate will be pushed slowly into the ICS-
Guide. Pay attention to proper and smooth operation.
• Plug the cable of the Integrated Capping Shutter into
the 26-pin socket ➪ photo on the lower right side of
the camera and screw tight.

4.5 Attaching the
Singleframe Hand
Control Unit SFHC-1
When attaching the Singleframe Hand Control,
damage can be caused to the shutter plate if it
does not slide into the ICS-Guide correctly.
Therefore check manually before attaching the
Singleframe Hand Control to see if the Capping
Shutter plate slides easily into the ICS-Guide
(see chapter Attaching the Integrated Capping
Shutter).
• Turn the SF or CAP switch ➪ photo to the OFF or
MAN position. Turn the 1x / INT switch ➪ photo to
the 1x position.
This switches off singleframe operation and the
Integrated Capping Shutter can later be operated by
the CAP-MANUAL key.
