PREFACE
Preface
At the beginning of the 21st century, the entertainment
industry more than ever demands broader knowledge
and greater skill from contemporary cinematographers.
Being used for feature films, miniseries, documentary
films, music promos or advertisements, all these different
kinds of productions request dedicated and versatile
cinematographic equipment. Because of the variety of
assignments today and tomorrow, cameras must be
mounted on dollies and cranes, on tripods and special
rigs, on Steadicam and sophisticated three axis remote
controlled heads, operated from the shoulder or on the
lap, in several extreme atmospheric conditions – these
are only a few out of a wide range of different tasks –
nowadays equipment must be flexible enough to allow
the best possible work without having to accept compro-
mises. So far, the inventive and creative cinematograp-
her and his/her crew have to get hold of cameras and
accessories suitable for all kinds of working situations.
Based on the huge amount of expertise collected during
designing and producing such cameras as the ARRIFLEX
435, 535 and 765 or the MOVIECAM Compact and
SL as well as with the intention to fulfil most of the desi-
res of today’s customers, the two leading companies in
the field, ARRI and MOVIECAM, have joined their
knowledge and inventive power to build a new line of
equipment, unifying the best of two worlds.
It was a real challenge for us to develop a system which
allows each cinematographer to set up the appropriate
equipment for each particular job more easily than ever
before.

01/2003 ARRICAM System Users’ Guide
PREFACE
The solution was to build up a wide range of
compatible accessories around two camera bodies,
each one optimised for dedicated operations.
The ARRICAM System Users’ Guide we herewith
present to you is not simply an instruction manual to a
new camera, but a handbook of an equipment line that
includes the most quiet compact 35 mm camera for
multiple applications and increased utilization.
Please take time to read the following pages carefully.
You will see that the ARRICAM System offers you a
great variety of possibilities. Like the camera system
itself, its System Users’ Guide consists of several inter-
changeable parts that will continuously be updated.
In visiting our home page www.arri.com, you will find
all updated information about all components of the
system. Furthermore, interesting news and publications
can be downloaded from there.
Frédéric-Gérard Kaczek AAC and the ARRICAM Team
Preliminary Remarks
The ARRICAM System is based on two different camera
bodies, each one with special characteristics. Even
though there are some important differences, several
parts of the two bodies are comparable in function and
design. Therefore, you will find some common descrip-
tions in the following pages.
Design and technical data are subject to change!

CARE AND CLEANING
Care and Cleaning
The ARRICAM System is almost maintenance-free.
There is only one requirement for a smooth operation:
the cameras and the accessories have to be meticulous-
ly clean. Therefore you should protect them against any
dirt or smudges.
Clean the camera exterior with a glass cleaner. Only
when really necessary, e.g. to remove camera tape
gum, alcohol or benzine should be used.
Caution!
1. When cleaning the equipment, do not moisten
connectors!
2. Never use acetone!
When applied properly, compressed air is the best
cleaner; a vacuum cleaner or an air syringe will do fine.
Cotton tips, orangesticks, soft and hard brushes may be
used for gentle cleaning.
Caution!
1. Compressed air should only be used for
blowing the magazines! Apart from this, high
pressure does more harm than good,
especially to glass surfaces.
2. The camera should only be lubricated at a
ARRICAM Maintenance Centre!

THE ARRICAM CAMERA BODIES
STUDIO LITE

The Camera Bodies
The cameras’ front
On the front of both cameras, an LDS 54 mm ARRI PL
(positive lock) lens port accepts lenses (spherical or
anamorphic) fitted with either LDS PL or with the well
established regular PL mounts. Depending on the way
the lens port is fitted to the camera front, the ARRICAM
Cameras will either allow shooting in Standard 35 or in
Super 35 format. The shooting mode is shown by the
number 1(for 35) or 2(for S35) facing the index.
Notice
It is recommended to ask a competent ARRICAM
Maintenance Centre or rental house to change the
format 35 to S35 or vice versa. If you have to do it
yourself, please see the related instructions in chapter
11 – Miscellaneous.
Different to the regular PL mounts of the ARRIFLEX and
MOVIECAM cameras, the LDS PL mounts of the ARRI-
CAM Cameras are equipped with little electric contacts
required to communicate lens data to the camera. Two
sets of LDS contacts are integrated in each lens port to
allow the fitting of the lens according to the need of the
focus puller. So the indexes of the lens can be seen
wherever it is requested depending on the shooting situ-
ations: from the top and the bottom or from the left and
the right side of the camera.
Notice
Even though there is a difference between the LDS
PL mount and the PL mount, all lenses fitted with
PL mounts can be mounted in the new LDS PL port.

To remove a lens (or a lens port cover), rotate the two bayo-
net levers counter-clockwise as far as possible while grasping
the lens firmly. Then carefully slide the lens out of the port.
To fit a lens, align guide groove in the lens flange with
locating pin in the lens port. Insert the lens flange flat on
the receptacle, making certain the stud engages the lens-
flange hole easily. Rotate lens lock gently clockwise to
secure until the lens is seated properly. Do not use force!
Notice
1. Especially because of the weight of some lenses,
great care must be taken that the lens is mounted
in (or removed from) a straight line port.
2. The LDS Lens must be mounted in the 12 o’clock
or 3 o’clock position to enable the LDS functions.
3. When attaching the lens or a cover, take great
care not to harm any elements (e.g. LDS contacts).
4. Heavy and long lenses, such as ZEISS Variable
Prime Lenses or zoom lenses, must be supported
at all times by means of dedicated accessories.
5. When mounting an LDS Lens, one must be sure
that the little contacts and the mount itself are per-
fectly clean in order to assure good electric com-
munication as well as an even fit of the lens on
the camera port.
On the STUDIO and LITE
THE DUST CHECK BUTTON
Because the mirror and the movement are driven sepa-
rately, moving the mirror by means of the inching knob
is not possible. It is also recommended not to move it
manually, there is danger of damage. To check the
gate, either by looking through the lens or by removing
it, turn the mirror out of the way by pushing briefly the
19
01/2003 ARRICAM System Users’ Guide
1 – THE CAMERA BODIES

DUST CHECK button. Even though the shutter opening
is preset to a value other than 180°, while operating
the DUST CHECK button, the shutter will open to 180°
and DC will appear on the FPS display(s).
Caution!
In case you need to clean the gate, it is impera-
tive to turn OFF the camera power first.
After having cleaned the gate, turn the power ON and
briefly push the DUST CHECK button to turn the mirror in
the viewing position – the shutter will be set to the preset
angle again automatically.
On the STUDIO and LITE
24V OUTLET RS CONNECTOR
Left of the lens port there is a 24 V outlet marked RS
(RUN/STOP). This three-pin Fischer connector is protec-
ted by a 1.6 A multifuse and may be used to remote con-
trol the camera status RUN or STOP as well as for supply
power to any kind of 24 V accessory, e.g. a zoom drive.

Only the ARRICAM Studio is equipped with a beeper.
Its volume can be increased in three steps by turning the
switch clockwise. The number shown on the switch will
indicate the adjustment: 1=low, 2=medium and
3=loud. When selecting the position 0, the beeper is
OFF. When the beeper is not turned OFF, it will sound
briefly when the camera is in RUN UP or RUN DOWN
status. It will beep intermittently as long as the camera is
RUNNING in ASYNC status.
On the STUDIO
LDB CONNECTOR
Hidden behind the front right side camera cover (fig.
1/3), a large connector is mounted on the camera
front. When the cover is removed, either a Lens Data
Box Cable Adaptor or the ST Lens Data Box itself can
be attached to this connector.
On the LITE
24 V HEATED EYECUP/WORK LIGHT OUTLETS
On both sides of the lens port, small connectors supply
the 24 V dc power for the following two accessories:
the Work Light and the Heated Eyecup.

CAC CONNECTOR FOR ACCESSORIES
The 16-pin Fischer connector, mounted oblique to facili-
tate the plug-in and labelled CAC (camera accessory
connector) is the main communication port of the
cameras. Several accessories can be attached there.
For further information see the accessory descriptions
and the fig. 1/8 and 1/9 on page 27.
POWER RECEPTACLE
The 2-pin Fischer power receptacle, mounted oblique to
facilitate the plug-in, is used to connect a 24 V battery
or a 24 V dc Power Supply Unit. Further information
about the power supply and power distribution of the
ARRICAM System is described in chapter 10 – Power
Management.
MAIN SWITCH
Protected by two flanges, the MAIN switch will interrupt
the power supply of all electronic components, except
the one of the clock in the In-camera Slate Box – it re-
mains powered to keep the clock working.
SCREWS FOR MAINTENANCE PURPOSES ONLY
On both camera bodies, there are several screws which
are dedicated to maintenance work only. These screws
are marked with a special seal lacquer and/or a safety
label.
25
01/2003 ARRICAM System Users’ Guide
1 – THE CAMERA BODIES

Caution!
Do not touch these screws, otherwise severe
damage can occur!
CAMERA OPENINGS
One of the main differences between both camera
bodies is that you are able to mount ST Magazines eit-
her on top or on back of the STUDIO by means of a
magazine adapter while the LITE allows the attachment
of the lightweight LT Magazines on the rear side only. In
order to install ST Magazines on the LITE, you will have
to use the LT Magazine Adapter.
On the STUDIO only
REAR CAMERA OPENING AND MAGAZINE ADAPTER
ATTACHMENTS
In order to mount one of the three ST Magazine Adap-
ters, swing the adapter towards the camera body while
taking care that the two adjusting pins enter the gauged
holes easily. Then you will have to screw the six retai-
ning screws firmly – see caution on page 88.
On the STUDIO only
CONNECTOR FOR THE SCB AND MCB
These two connectors allow the mounting of the Speed
Control Box (SCB) and the Manual Control Box (MCB)
– see chapter 7.
