INSTRUCTIONS

2
The Canon Servo EE Finder is interchanged with the
pentaprism section
of the Canon F- ', cou pled to the
full aperture metering mechanism and preset to the
proper f/stop
automatically with shutter speed pri-
ority. It is vibration- and shock-proof, and has fast
response
to light intensity because of the use of a
servo-
motor . Metering information can be read off
inside the viewfinder. Since the Centr al Emphasis
Metering system is used, a most satisfactory
exposure
can be obtained when shooting scenery
that includes the sky.
Unmanned continuous shooting, such as recording
for ecological and other experiments, is possible
through the combi ned use of the Motor Drive Unit .

Loading Batteries
The Battery Case, conta ining Battery Magazine 12V
with eight penlight (size AA) batteries or Battery
Magazine 15V with ten penlight batteries, is used
as
the power source for the Servo EE Finder .
1 To load the penlight batteries into the Battery
Magazine 12V, first remove its cover by loosening
the two knobs. I nsert the batteries properly accord-
ing to the diagram outside the Magazine. And then
replace the cover by matching its three projections
with the holes on the Magazine and by tightening
the knobs .
• Load the batteries into Battery Magazine 15V by
inserting minus
(-) poles first.
• The NiCd batteries come as a unit .
2Remove the bottom cover of the Battery Case
by sliding it either to left or right. Facing the
battery contacts upwards, load Battery Magazine
12V
properly by matching the groove on Battery
Magazine 12V and the gu ide line inside the Battery
Case, and replace the bottom cover.
The Battery Magazine 15V can be loaded by match-
ing the green marks on the Magazine and inside
the Battery Case.
3Replace the bottom cover of the Battery Case.

The Battery Case and the Servo EE Finder are
connected by the Cord 12V 2E .

A ttaching Procedure
1
While depressing the EE lock pin, set the
aperture ring of the lens at the "A" mark for EE
use.
2Slide the pentaprism section of the camera
backwards
and remove it by depressing the at -
tachment stoppers. Remove the dust cover of the
Servo EE Finder.
3 Set the shutter speed dial of the camera any-
where between "'" and "30". The shutter speed
dial of the Servo EE Finder can be set anywhere .
4Align
the attachment rails of the Servo EE Finder
and sl ide in from the rear.
5
Turn the shutter speed dial slightly to left or
right, so that it will couple with the shutter speed
dial of the camera.

6 Set the film speed scale on the Servo EE Finder
at the film speed of the film to be used Lift and
turn the ring around the shutter speed dial. This
can be
performed more easily while ' pressing the
center of the dial.
• When detaching, slide the Servo EEFinder back-
wards while depressing the attachment stoppers.
7 Connect the Battery Case to Servo EE Finder by
using
the Cord 12V 2E. Plug the connectors into
the Finder and the Battery Case, and then tighten
the connector of the Battery Case side by turning
its outer ring.
8 By setting the main switch at "M", the servo
operation pin will descend to its attachment
position.
• The Servo EE Finder will function properly only
when the servo operation pin is at its attachment
position. Be sure to perform the above operation
before attaching the EE Coupler.
9 Open the cover for the servo operation pin, situ-
ated
on the camera by the side of the mirror box,
insert the EE Coupler while aligning its attachment
position, and tightening it with the coupler attach -
ment screw.
10Adjust the lens speed adjustment dial by set-
ting
the proper lens speed, i.e., the full opening
f/number of the lens to be used.
• The lens speed scale of the adjustment dial:
(1.2)
1.4 (1.8) 2 (2.5) 2.8 (3. 5) 4 5.6
Figures in parentheses denote values for white
dots.

11 When the lens speed adjustment dial is turned,
the f/stop scale of the meter readjng window
slides and the lens speed is indicated just below
the under-exposure warning mark as a maximum
f/stop.
When the aperture needle points to the under- or
over-exposure warning mark, change the shutter
speed.
Use
the auxiliary warning mark as an over-exposure
warning
when u~ing lenses with the minimum f/stop
of f/16.
12 Set the main switch to the red mark.
13
Press the battery check button on the rear
section
of the Finder. If the indicator lights up,
it means there is sufficient power level in the bat-
teries. Otherwise, replace all
of the batteries simu 1-
taneously with the same make.

Operation
1First, decide the speed.
2Use either the main switch or lever switch. Full
aperture metering is used.
3When
the main switch is at the red dot position,
the power circuit is disconnected . However, if the
lever switch is depressed, the circuit is connected and
metering starts by motor drive.
When
the proper f/stop is obtained, the motor. and
aperture needle will stop. When you release your
finger from the lever switch, the aperture needle
becomes
clamped . Proper exposure is obtained when
the shutter release button is depressed.
• This method is convenient when shooting is con ·
tinued with a fixed f/stop .
4When
the main switch is set at "L", the lever
switch
is also fixed at "L" position, and contin°
uous metering becomes possible. Depress the shutter
release button after the motor drive has stopped
and the aperture needle has pointed to the proper
value.
When
the lever switch is returned to its former
position, the main switch is released from its locked
condition and reset at the red dot .
• When shooting with the main switch in a locked
condition, use a shutter speed faster than 1/ 15 sec.
If slower shutter speeds than 1/8 sec. are used,
the picture will be over·exposed because the mirror
sprinQs up
and cuts off the light coming to the

17

18
CdS photocell which in turn activates the motor and,
shifts the aperture to the full opening side.
5When the main switch is set at "M", the EE
circuit is disconnected and the aperture can be
set manually:
• This
method is not recommendable because the
servo motor circuit is not disconnected and the
power is consumed.
• The aperture cannot be manually closed down
beyond the flstop indicated in the meter reading
window, if the main switch is not set at "M".
6When the shutter dial is set at "B", the EE
circuit is disconnected and the aperture needle
points to the bottom of the meter reading window.
In this case, the aperture can be also present manu-
ally.
• When using a
shutter speed at or slower than 1/8
sec., be sure to use the method as described in
item If 3 by setting the main switch at the red dot.
Detaching Procedure
1When removing, be sure to first detach the EE
Coupler before removing the Servo EE Finder.
Otherwise, the coupling socket will be damaged.
2Slide the Servo EE Finder towards the rear while
pressing
down on the attachment stoppers.

Joint Use with Motor Drive
When used jointly with the Motor Drive MF, con-
nect
the MF to the Servo EE Finder by using the
Connecting Cord MF for Servo-EE. When used with
the Film Chamber 250 at the same time time, con-
nect
the Motor Drive MF to the MF's grip (fgr the
battery case) by using the Connecting Cord MF.
When used
jointly with the Motor Drive Unit,
attach the Battery Connector MD to the Battery
Case, and then connect the Connector MD to the
Servo EE Finder by using the Cord 12V 2E. The
cord of Battery Connector MD is connected to the
Motor Drive Unit.
The setting of continuous, single-frame and high
speed
photography and the selection of the shutter
speed is performed by the Motor Drive.
• Continuous lock of 1/8 sec. or under is not
possible when the Servo EE Finder is used in-
dependently. However, when it is used jointly with
the Motor Drive, slow shutter speeds can be selected.
