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. Introduction 3.
Installation 26 pin socket 8
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 runup, which is usually not used anyway.
Installation 4.2 Preparing the Film Gate format mask film gate locking lever knurled knob filter holder movement locking lever 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.

• Remove the three screws from the magazine locking cover ➪ photo. • Remove the magazine locking cover. • Hold the film recognition module tightly to prevent it from falling onto the movement block and damaging the module’s surface. screws Installation • Switch off the main camera switch and remove the camera from the power supply. • Unscrew both fastening screws ➪ photo.
Installation • Remove the film recognition module ➪ photo by pulling it towards the movement block. TC- or film recognition module When attaching the new module, ensure correct plug positioning as otherwise damage could be caused to the plug contacts! • Attach the singleframe film recognition module ➪ photo. • Screw tight the two fastening screws ➪ photo (page 13). • Replace the magazine locking cover and fasten with the three screws ➪ photo (page 13).
screws 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.
Installation • Press the control knob ➪ photo on the Integrated Capping Shutter and turn until the black plate reaches the ICS-Guide. Note: control knob shutter plate 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 ICSGuide, as this could damage the plate or the guide. ICS-guide hex screw for height adjustment • Check that the plate can be pushed into the ICS-Guide easily and without catching.
door locked 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 ICSGuide. Pay attention to proper and smooth operation. Installation • Press the control knob of the Integrated Capping Shutter and turn it until the black plate disappears in the ICS door. Close and lock the ICS door.
Installation 4.5 Attaching the Singleframe Hand Control Unit SFHC-1 SF ON / OFF switch 1x / INT switch 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.

The camera, once modified for singleframe operation, can be used normally with some restrictions. The following points should be taken into consideration: The camera may be operated at max. 120 fps with the special singleframe film recognition module, as at higher speeds the camera is in danger of switching off while running or may damage the film. Switching on Normal Operation • Turn the SF ON/OFF switch to the OFF position. The camera can be used normally.
6.1 Light-Tightness 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 runup, which is usually not used anyway. On singleframe shots however, the stray light, which can fall onto the film around the mirror shutter during interval time, can affect the quality of the exposed singleframes.
Integrated Capping Shutter 24 The following five important rules result: Never shoot singleframe shots without the Integrated Capping Shutter. During interval times of over an hour use an external Capping Shutter in addition to the Integrated Capping Shutter. To ensure that the light-tightness of the camera is sufficient, check for light-tightness under the same conditions as the intended shots.
Attaching the Integrated Capping Shutter has already been described in the chapter Attaching the Integrated Capping Shutter. LED CAP OPEN / CLOSE LED CAP-MANUAL key CAP-MANUAL 6.2.1 Singleframe Operation switched off SF ON / OFF switch As long as the singleframe function is switched off by the Singleframe Hand Control (SF switch in position OFF), the Integrated Capping Shutter can be opened or closed by pressing the CAP-MANUAL key ➪ photo.
Integrated Capping Shutter 26 control knob 6.2.3 Manual Operation (only in case of failure or while attaching) To open the camera door in case or power failure, and when attaching the Integrated Capping Shutter, it is possible to manually operate the plate on the Integrated Capping Shutter. • Switch off the camera’s main switch and remove the camera from the power supply.
The Singleframe Hand Control Unit SFHC-1 facilitates setting all parameters necessary for the exposure of singleframe shots. The Singleframe Hand Control takes over control of the camera and the attached Capping Shutter as soon as the SF switch is ON ➪ photo. In the position SF OFF, only the Capping Shutter can be operated.
Singleframe Handcontrol 28 7.1 Switching on Singleframe Operation SF ON / OFF switch Before switching on singleframe operation, ensure that the singleframe guide is correctly installed, that the plate on the Integrated Capping Shutter can be moved easily, that the Singleframe Film Recognition module is attached, that the cover for the openings in the film gate is correctly attached and that the eyepiece is closed (see chapter Preparing the ARRIFLEX 435 for Singleframe Shots).

Then the Singleframe Hand Control waits until the exposure key is pressed again. • The 1x / INT switch ➪ photo must be at the 1x position. 1x / INT switch 7.2.1 Setting the Repeat Counter (burst) The repeat counter ➪ photo sets the number of singleframes which will be recorded each time the exposure key ➪ photo is pressed.
Singleframe Handcontrol 30 7.2.2 Setting the Exposure Time EXPOSURE key 1/SEC SEC switch exposure time 1x / INT switch The shortest exposure time with a camera shutter angle of 180° is 1/8 second. All shorter exposure times are set by adjusting the angle of the mirror shutter on the camera. The ARRIFLEX 435ES is equipped with an electronically adjustable mirror shutter. This enables the shutter angle to be automatically adjusted for shorter exposure times by the Singleframe Hand Control.
7.2.3 Recording Singleframes • Press the exposure key ➪ photo. • With the 1/SEC SEC switch ➪ photo, select if the exposure time is displayed as whole seconds or as fractions of a second. After pressing the exposure key the Integrated Capping Shutter opens. Then the number of singleframes set on the BURST FRAMES switch will be recorded with the set exposure time. After the last singleframe the Integrated Capping Shutter closes again. • For further singleframes press the exposure key again.
Singleframe Handcontrol 7.3 Intervallometer Operation EXPOSURE key 1/SEC SEC switch 1x / INT switch The interval time is defined as follows: it extends from the opening of the Integrated Capping Shutter for the first singleframe of a singleframe cycle to the opening of the Integrated Capping Shutter for the first singleframe of the next singleframe cycle. exposure time Interval Time HRS:MIN / MIN:SEC BURST FRAMES For intervallometer operation the 1x / INT switch ➪ photo is set to the INT position.
Note: If the repeat counter is set to 0, one frame will still be recorded when the exposure key is pressed. 7.3.2 Setting the Exposure Time The shortest exposure time with a camera shutter angle of 180° is 1/8 second. All shorter exposure times are set by adjusting the angle of the mirror shutter on the camera. The ARRIFLEX 435ES is equipped with an electronically adjustable mirror shutter. This enables automatic adjustment of the shutter angle for shorter exposure times by the Singleframe Hand Control.
