THE MULTIDUTY MOTOR (MIVAR)
This brushiess motor (6) has a very
high efficiency (from 0.8 to 1.2 amp. con-
sumption at 12 volts to drive the camera at
20°C (68° F) and has permitted a weight
reduction not only in the camera but also in
the battery (37) - page 12 - which weighs only
640 grammes enabling one hour of filming
between recharges, i.e. eight to ten 60 m
magazines.
The incorporated electronics (7)
control the sync. speed by crystal ; changing
from 24 to 25 f.p.s. or vice-versa is made by
shifting switch (38) so that the white spot
mark is adjacent to the desired speed. Others
speeds : 8.12.50 and 75 are obtained by
setting the engraved button 35 accordingly.
The MIVAR will stop the camera
automatically in viewing position,
i.e. the mirror being in the aperture axis
allows the cameraman to frame and focus
without
loss of time. See pages 24 and 30.
The motor will only operate when it is
attached to the camera.
The lamp (47) on the motor lights up
until the marked speed is attained. In the
event of speed reduction (flat battery for

THE 60 m MAGAZI N E
The two chambers of this snap-on co-
axial magazine are separated by a median
partition and are connected by a light tight
ramp for the passage of the film from the feed
side to the take-up side (Fig F).
THE 120 m MAGAZINE
Bearing in mind the versatility and light
weight of the 60 m magazine which can be
changed almost instantaneously, there are
occasions where a « long take » in excess of
60 m is required and for this purpose a 120 m
capacity magazine is available.
This co-axial magazine retains all the
characteristics of simple threading and snap-
on action for which the Eclair equipment is
famous.

THE HAND-GRIP
The portability of the ACL is increased by
the use of the hand-grip (36) supplied with the
camera.
Adjustable in the horizontal and the
vertical plane, it permits the choice of the most
confortable position. It can be screwed either
under the camera base or on the right hand side
of the camera (fig K).
To carry the camera, the hand-grip (36)
with its knurled knob (79) - fig. QR - can also be
screwed on top of the camera head.
MOUNTS AND LENSES
The ACL has been designed to accept
« C » mount lenses (fig Q, the mechanical back
focal distance of which are 17.52 mm, and also
other professional mounts such as Eclair CA (fig
M) Arriflex, Nikon, etc... the mechanical back
focal distances of which are greater than 17.52
mm.

sional equipment manufacturers 48 mm for
ECLAIR (Eclair CA), 52 mm for
Arriflex, 46 mm for Nikon, corresponding
intermediate Eclair TS mounts (Fig P-P’-P”-)
can be supplied for these different makes of
lenses for use with the ACL camera. For Arrif
lex, specify « normal mount » or « new steel
bayonet mount ».
Hence, the ACL lens support (1)
comprises an internal threading (21) the
diameter and the thread pitch or which corre-
spond to the C lenses standards and an
external threading (22) for the Eclair TS
mounts (Fig P-P’-P”); the orientation of the
lens is ensured by the slot (23) at tfie top of
the flange.

• Its position, away from the fi I m plane en-
sures any small dust or finger marks on the
gelatine that may occur are out of focus on the
final result and rarely visible.
Shutter
Contrary to reflex cameras in which the
mirror mounted at 45' acts as a shutter, the
ACL has a plane shutter of large diameter
completely independant of the mirror (14). It is
placed very close to the film plane with an
opening of 175'. Cutting the image in the
direction of the smallest dimension gives a
perfect exposure, maximum definition and
reduction of jerky effect on some panning
shots. The exposure time is 1 /51 of a second
at 25 frames per second and 1 / 49 of a sec-
ond at 24 frames per second (page 33).
GENERAL INFORMATION
REFLEX SIGHT
The reflex image is obtained with an
oscillating mirror (14) moving at half camera
speed, which transmits the image formed by
the lens onto the ground glass during the
descent of the film.
The viewf inder (focussing tube) is a
new mechanical /optical realization which
gives an exceptionally bright image.
As on the Eclair 16, the ground glass
gives a field of view greater than the recorded
image, which eliminates the possible intrusion
of microphones, etc... into the recorded
picture. (Fig Q).
This viewfinder - 10 x enlargement -
can be used for left eye or right eye viewing it
can pivot through 360' parallel to the camera
thus allowing the cameraman to frame and to
focus in the most comfortable conditions
whatever the position of the camera; for
example, he can shoot with his back facing
the subject. The eyepiece is adjustable of ±
5dioptres.
The standard ground glass is en-
graved with the 16 mm frame (10,2
x 7,4 mm), the TV frame and a cross in the
centre (UER standard).
Gelatine filter holder
Each ACL is equipped with a gelatine
holder 2 (Fig A and R) which is located between
the C mount and the reflex mirror close to the
rear element of the taking lens. Its advantages
are :
• It is not necessary to change filter at each lens
change.
• It is possible to check the presence and type of
gelatine through the viewf inder.
• It eliminates the requirement for front glass
filters for each lens diameter, the price of which
is very high compared to that of gelatine filters
which are readily obtainable.

Mechanism
The complete silent mechanism is
mounted on the mechanism plate which
greatly reduces the time required for the
normal overhaul and cleaning which we
would strongly recommend to be carried out
by one of our agents.
The claw movement (13) is controlled
by an excentric and a fixed cam (39), the
security is ensured by a counter-cam.
The four drive shafts run in self-
lubrificated bearings and the camera mecha-
nism should NEVER be oiled.
As already indicated page (4), the
aperture plate of hard chromium-plated steel
has, on the left, a fixed guide (11) which is the
edge reference for the film and a spring
loaded guide (12) on the right, which main-
tains the film against the fixed guide.
The two guides (29-30) fig B position
the magazine nose onto the mechanism
plate.
adjusting the diaphragm if he needs a special
effect by under or over exposure, e.g. contrast.
Before filming, the operator sets the
exposure indicator with the aid of his profes-
sional photo- cell exposure meter indicating the
diaphragm opening (stop) of the lens; it gives
him a reference lighting intensity « EO ». The
camera being connected to the battery, he
adjusts the sensitivity potentiometer (34) so that
only the middle diode EO, visible in the
viewfinder, lights up. Thus the camera is now
matched to the exposure meter.
During filming, if the lighting intensity of
the subject varies, the control diodes visible in
the viewf inder will be seen light up either + or -
. The operator wiII then correct the diaphragm
of his lens so as to maintain the lighting inten-
sity on the film to a value of EO, if he deems it
necessary.

Exposure indicator
The ACL camera had to have a very
safe « Exposure Indicator device » because
of the professional work it must ensure. It
could not be question of an ordinary photo-
cell system due to the fragility of moving
parts; on the other hand, a 100% automatic
device leaves the cameraman no change of
artistic creation.
The basic idea is to leave the camera-
man freedom to determine the exposure of
the film and thus give him the possiblility of
working according to his own technique; in
other words he must have the possibility of

ELECTRONIC BASE 150 E
This unit (8) forms a flat base
for the camera body and consists of:
• 1 Jaeger socket (19) for power supply
to the camera.
• 1 Sliding on/off switch (32) at the front part.
• 1 Cannon socket (33) for the accessory
power supply.
• The stabilized 5 volt supply.
• 1 Souriau socket for electrical connections
with the camera head.
• 1 sensitivity potentiometer (34)
for adjustment of the exposure indicator.
• 1 Clapper switch (20).
This flat base is provided with the stan-
dard congress 3/8 tapped hole for tripod mount-
ing or hand- grip mounting (36).
PILOTONE MODULE
The ACL servo-control led crystal motor
allows the shooting of sync. sound without any
cable connection between the camera and the
tape recorder if the latter is equipped with a
crystal controlled motor (e.g. Nagra 4,
Perfectone E P 6 A2, Stellavox). Such a system
(diagram KL) does not permit the use of the
clapper.
If, however, the two units Camera and
recorder are connected by a cable, the clapper
will function (diagram L M). See additional
information page 29 for connection and use.
When the recorder has no crystal, the
synchronization can be ensured by using the
Eclair pilotone- module (option) which contains
its own signal.
THE ECLAIR PILOTONE MODULE is
contained in a metal cover. Its size: 92 x 66 x 23
mm is slightly larger than a packet of 20 ciga-
rettes (fig. Y and Z). it is a crystal pilot f req
uency generator 50-60 and 100 H Z.

THE BATTERY (MIBAC)
The low torque ot the camera and the
high efficiency output of the motor have
allowed the construction of a low power
battery (1,2 amp-hour) which at 20°C (68°F)
provides power for ten 60 m (200 ft) maga-
zines i.e. for about 600 meter of film. This
battery (37) weighs less than 1-4 lbs (640
grammes). It is a Saft type VIR 1.2 ten cell
cadmium-nickel which is enclosed in a poly-
urethane case (48) fig. AB.
The battery is equipped with a textile
shoulder strap although its small size will
allow it to be slipped into a coat or trousers
pocket.The connections with the camera and
the pilotone-module can be made from either
of the Jaeger 4 pin-sockets (49). The central
Socapex socket (50) is provided for the rapid
charger.
CABLE. The same type of cable
(MIBLE) is required for connecting the cam-
era, the battery and the pilotone-module. It is
fitted with two Jaeger plugs ref : No 530800.
Our V.R. mini-cell battery has been
conceived for a recharge in less than 30
minutes by means of our MIRAP charger
connected to the mains between 115 and 220
volts A.C.
THE CHARGER (MIRAP)
The MK2 charger specially made for our
MIBAC battery is automatic and very simple to
use. It ensures a charge feed regulation of
± 20 % for a variation of the main supply tension
of ± 10 %. It stops the high speed automatically
as soon as the battery has attained a tension
which is related to the charge rate and the
temperature of the battery.
The cut-off precision is approximately 1
Immediately after the high speed charge has
been cut-off, the charger switches automatically
to the low charge rate.
The thermostatic protection is ensured
by a thermal limiting device which cuts off the
charge if the battery temperature becomes
abnormaly high e.g. because of irregularity in
the cut off safety circuit

BATTERY (BAKEL)
CHARGER (CIBRE)
If a battery having a larger capacity
than the MIBAC battery is desired, especially
if the camera is often used at higher speed
than the standard, we can supply the BAKEL
battery (of the Eclair NPR 16) type VR 4 (4
amp-hour). It is a 12 volts cadmium-nickel
battery - Fig EF - with a discharge controller
(Schoeller galvanometer) and is supplied in a
plastic box made of unbreakable black poly-
ethylene with a carrying textile belt.
It is composed of 10 insulated cells
SAFT type and weighs 1,650 kg; its dimen-
sions are 230 x 150 x--40-mm and its capac-
ity is equivalent to ten to fifteen 120 m (400 ft)
reels. Its use necessitates a connection cable
« Camera/ Battery » (BABAC), a 220/110 v -
12 V charger (CIBRE) and a connection cable
« Charger-battery » (COURT).
The BAKEL battery can be also suppl
ied in a leather belt with built-in charger, its
code is BACHA. Its weight 2.750 Kg; only the
connection cable « Camera/ Battery »
(BABAC) is necessary.
The new compact charger CIBRE type
76 is very smal I : 125 x 64 x 40 mrn and
weighs only 420 grammes.
An internal tension selector permits its
utilization on 220 or 110 volts; safety is en-
sured by a 500 mA fuse. A 2 metre connec-
tion cable « Main/Charger » is supplied.
The CIBRE charger bears, at one end,
a 3 pin socket (mains side) and at the other
end a 4 pin Amphenol socket for connection
to the battery; two control lamps : one red and
one green light up as soon as the charger is
connected to the main. The green light cuts
off when the load is over.
The select the voltage in the charger
(110 or 220 volts) or to replace the safety fuse,
unscrew the 4 screws of the lid ; take- off the lid
without dropping the screws, select the tension
or replace the fuse, put the lid back and tighten
the screws.
CARRYING CASE
Made in shape of a rigid suit-case(fig
GH) and not like an ordinary transport case, the
framework is anodized aluminium supporting
two shells in ABS which is a very high impact
resistance material. The inside is entirely pad-
ded with expanded polyethylene cut out to the
form of a complete ACL equipment : Camera

INSTRUCTION MANUAL 2nd PART -
When you receive your equipment for
the first time we recommend you examine
every unit individually in accordance with the
information given in this brochure.
After that, you will be able to follow the
instructions for use more easily.
MOUNTING A “C” LENS
• Remove from the camera the protective cap
of the lens mount.
• Remove from the lens the cap protecting the
thread.
• Remove any dust from the flange with your
finger.
• Screw in the lens in 21. Fig. 0.
If the distances and stops engraved
on the lens barrel cannot be read by the
cameraman in the normal operating position :
take the lens off the camera.
The threaded ring at the bottom of the
lens is mounted in contact with a special
spring washer. Without touching the rear lens
element, press down firmly on that threaded
ring and turn it to modify the orientation of the
distances and stop marks with respect to the
thread start.
MOUNTING AN ECLAIR “CA”
MOUNT LENS
• Remove the protective cap and the guard ring.
• Remove any dust from the flange with your
finger.
• Locate the intermediate TS-CA mount (fig. P)
on the lens support plate ensuring that the
locating pin (24) enters the slot (23) of the
flange.
• Screw up the retaining ring (25).
• Position the lens so that the slot (26) in the CA
mount is vertical. 9 Push the lens into the TS
intermediate mount and lock by turning the lens
clockwise.
As you will notice the Eclair intermediate
TS mount is exceptionally robust with a large
locating diameter and thrust face. The use of
lens supports with the mount is not necessary.
It is strongly recommended that each
zoom lens is fitted with an intermediate TS
mount to prevent the deterioration of the limit
stops on the lens after repeated locking in place
on the camera.

DIOPTRY ADJUSTMENT
OF THE VIEWFINDER
Legend of the external parts of the viewfinder:
Ll - Eyepiece with shutter and rotatable rubber
eyecup.
L2 - Control ring of eyepiece shutter.
L3 - Locking knob of the dioptry adjustment ring.
L4 - 360' rotatable viewf 1 nder unit.
L5 - Eyepiece support with rocking motion
for left and right eye sight.
L6 - Locking ring of the rotation of the eyepiece
support.
L7 - Adjusting ring for partial positioning
of the ground glass image.
L8 - Clutch for final adjustment of the ground
glass image.
Everyone having a different keenness of sight, it
is necessary for the camera user to set exactly and then
lock the dioptry adjustment which corresponds to his
vision. This can be done with or without lens mounted
on the camera.
Adjustment with a lens:
1. Place L5 to the right or to the left according to the eye
you normally use.
2. Make sure that the reflex mirror is in the front of the
aperture, if not, turn knurled button 31 which controls the
motor axle (see page 24, par. 5)
3. Turn control ring L2 to open the eyepiece shutter.
4. Focus the lens on infinity.
5. Diaphragm wide open or slightly closed to darken the
ground glass.
6. Loosen knob L3 and turn slowly in one way and in the
other the dioptry control ring until the frame and cross
engraved on the ground glass are perfectly sharp.
7. Take note of the number of dioptries in + or - that
corresponds to your sight. Lock the dioptry control ring in
that position by tightening the button L3.
This setting should always be kept as it will permit
you to focus sharply at any distance.
18
Fig. PQ

Adjustment without lens :
Direct the camera towards a well
lighted part (sky, for example) and follow the
preceding instruction 1-2-3-6- and 7.
Instruction for use
Position L5 for your left or your right
eye, as needed. Make sure the dioptry adjust-
ment is correct and the button L3 is perfectly
tightened.
If the image on the ground glass is not
optically horizontal, turn ring L7 in one way or
the other to level the image. If you.come to
the thrust before the image is in the right
position, turn L8 in the reverse way and move
again L7. Once the image has been so
erected the viewf inder can be pivoted
through 3600, a Wollaston prism will keep it in
the correct position.
If you shift L5 from left to right or vice-
versa the image will reverse gradually until it
is up side down; just turn L8 to declutch L7
and turn same to reset the image to its nor-
mal position. A positioning "clic-stop" is
provided in L6 to set the eyepiece Ll in hori-
zontal and vertical positions.
GELATINE HOLDER
Fitting a gelatine to the holder
• Pull out the gelatine holder
• Open the holder by pressing the button (27)
• Place a 2" margin (5Ox5O mm) gelatine
in the holder and close it.
• Cut the gelatine closely to the shape
of the holder with a razor blade.
• Replace the holder in the camera, chamfered
side forward.
• The correct positioning of the holder can be
verified by checking that the aperture
is concentric with the C mount aperture.
NB. Never place more the one gelatine in the
holder. Always film with the holder in place (with
or without a gelatine) to avoid the possible
fogging of the film.
The fact of filtering behind the rear
element of the taking lens may cause a slight
alteration of the focussing distances engraved
on the lens which will be automatically compen-
sated if focussing is done through the reflex
viewfinder.
FITTING THE HANDGRIP
Under the camera :
• Screw the handgrip support - Fig. QR -
into the electronic base using the knurled
ring (27)
• Fix the handgrip (36) in the hole (80)
of the support.
• Loosen the ring (79), set the position
of the handgrip and tighten the ring (79).
• Loosen the half-moon (81), set the handgrip
at the desired angle and retighten lock (81).
Onto the right hand side of the camera:
• Fix the handgrip (36) to the side support (75)
and lock it in the best position by means of lock
(81).
NB. The unit (79-80) - Fig. QR - is not used in
this case.

FUNCTIONS OF THE
ELECTRONIC BASE 150 E
a) On/off switch (32)
This is a double action switch : it puts
under tension the diodes of the exposure
indicator, without starting the camera. Or it
sends the power supply to the motor to start
the camera. tee page 24 detailed instruction.
b) The clapper switch (20)
In the central position this switch
provides no clapper.
In outside right position : the clapper is
automatic and provides fogging of the film for
0,3 secondes at each start.
In inside left position : the clapper
functions (0,3 seconds) at every manual
pressure when the camera is running; this
allows, for example, to clap at the end of
filming, before switching off the motor.
Thus, the clapper ensures two func-
tions 1 0 - Automatic fogging of the film during
0,3 seconds at each start of the camera or
manually at any moment. 20 - The supply of
an 8 volt signal to the battery during 0,3
seconds (bloop) if the pilotone module is
connected to the battery and the recorder, the
signal triggers a 1 Kc signal on the recording
tape.
c) The running signal:
A 12 volt signal available from the Jeager
socket supplies the pilotone module and
ensures that the module only produces a 12
volt signal when the camera is running.
This signal can also be used to start a
sound recorder from a distance.
d) The output signal :
1 - Tachometric signal
This 3,8 volts square signal (peak to
peak) is supplied by the motor. Its frequency is
given by the motor speed multiplied by 40, that
is to say 1000 Hz for 25 images per second and
960 Hz for 24 images per second. This signal
directly supplied by the motor can be used for
various purposes after it has been divided.
2 - Crystal signal (for MIALA motor only) :
This is a 100 mV sine signal (peak to
peak). Its frequency is 1024 KHz for 25 frames
per second and 983.04 KHz for 24 frames
persecond.
