coin into the groove of the battery compart -
ment cover and turn to the left to remove.
2Face
the central contact of the mercury battery inwards
and insert.
3Replace the cover by turning it to the rig, ht .
• Before inserting,
wipe all battery poles clean of finger-
pr i nt s or stains with a dry cloth . Unclean poles may cause
corrosion and damage the contact points of the camera.
• A 1.
3v M20 (# 625) mercury battery should be used-
equivalent to Mallory PX-625, Eveready EPX - 625, Burgess
Hg-625R.
•

Battery Check
To check the power level of the mercury battery :
1Set
the film speed scale at ASA 100, the shutter speed
dial
at the "30" index. For the film speed setting, lift
up the outer ring of the shutter speed dial and turn.
2
Turn the EE/ Manual switching ring to "EE" and aim the
camera at the sky or other bright subject. If the exposure
indicator inside the viewfinder swings up to and over the
"16" index, the battery has sufficient power. Otherwise,
the battery must be replaced.

Checking Correct Film Loadin~
The film is properly loaded and advanced if the film rewind
c rank rotates when you wind the film advance lever. If
the rewind c rank does not rotate, take out the film as ex-
plained on the following page, and reload .
@

Film Winding
The film advance lever winds the film, cocks the shutter ,
and prepares the
mirror for the next shutter release all in
one motion.
1
Turn the film advance lever until it stops. The film
will be advanced one frame and the shutter cocked.
The frame
counter is simultaneously advanced to the next
number .
2When the
shutter release button is depressed, the mirror
flips up, the diaphragm simultaneously closes down to
the proper f/stop (in case of manual control, to the pre-set
f/stop) and the shutter operates. After the shutter is operated,
the advance lever can be wound for the next frame.
• Winding
may be done by moving the lever with several
short strokes.
•
After loading the film, make another wind, because only
with the first wind it may not be completed.
• The
shutter will not function when depressing the shutter
release. button unless the winding is completed. In such
a
case , check the winding once more .
Frame Counter
Each winding will advance the number of the frame counter,
indicating the number of pictures taken. Whim the back
cover
is opened, the indicator automatically returns to starting
position "S" .

Film Speed Setting
When loadi r;l g the film, be sure to set the film speed scale
at the proper position .
Lift the film speed set ring around the shutter speed dial,
and set the proper ASA film speed number.
• The film speed is indicated on the film box or on the
instruction sheet.
Photography with Electric Eye
For taking pictures with Electr ic Eye, set the aperture control
ring at "EE" .
•
The Electric Eye is fully coupled to the ASA film speed,
the shutter speed and the aperture. The diaphragm will
close down to the proper f/stop and exact exposure is
determ ined by simply depressing the shutter release button.

Shutter Speed Adjustment
Adjust the shutter speed by turning the shutter speed dial
to the desired index number. The index on the dial shows
the denominators of 1/500 sec ., 1/250 sec ., etc.
• Be sure
to set the index at a position where the click-
stop catches.
•
"B" indicates bulb exposure, and is used when making
indefinite timed exposures. When the shutter speed dial
is set at "B " , the shutter remains open as long as the shutter
release button is depressed.
•
Time exposure, making an exposure over an extended
time, is possible by using the lockable cable release and
setting
the shutter speed dial at " B" .
•
The " 60" index is used for synchronizing an electronic
flash unit such as Canolite D. Although the shutter speed
at " 60" is 1/60 sec ., it is equivalent to a very short exposure
time during the flash of the electronic flash unit .

Focusing
The center of the viewfinder (circular section) is a micro-
prism screen rangefinder made up of ' microscopic prisms for
fast and precise focusing .
While looking through the viewfinder, rotate the focusing
ring . It is in focus when the image in the rangefinder becomes
sharp and clear.

Viewfinder
The exact picture image to be photographed can be clearly
seen through the viewfinder without any parallax . T his
enables you to determine the exact composition of your
scene before depressing the · shutter release button .
• Canon Angle Finder A can be attached . to the eyepiece
for copying and close-up photographies . In these cases ,
images are reversed between left and right.
• The Canon Magnifier can be attached to the viewfinder
eyepiece of the Canon EX AUTO, with the separately available
adapter which magnifies the rangefinder section for accurate
focusing . Because it can be sprung up and clamped, the
entire field of view can easily be viewed after focusing .
• Dioptric adjustment lenses are available as optional attach-
ments . When a dioptric adjustment lens is attached to the
viewfinder eyepiece, those who are far-or near-sighted can
take pictures ' without glasses. Four different diopters of
+1.5, 0, -2.5 and -4 are available.
• When
photographing without the eye close to the eyepiece
such
as when using the self-timer, use the accessory shoel
eyepiece cover to prevent the incorrect exposure caused by the
influence of the reverse incoming light entering the eyepiece.

Checking the E~posure Indicator
Turn the aperture control ring to "EE". Point the camera
at the subject and check the position of the exposure indicator
inside the viewfinder.
1
You may depress the shutter release button if the indicator
is pointing inside the proper exposure range.
2
If the indicator is painting to the over-exposure warning
mark, either the shutter speed dial should be revolved
to the higher index side until the indicator moves to the
proper exposure range, or a neutral density (NO) filter must
be attached to restrict the incoming light.
3
If the indicator is pointing to the under -exposure warning
mark, either the shutter speed dial should be revolved
until the indicator moves to the proper exposure range, or
light source must be increased.
•
Upper splitted part of the under-exposure warning mark
applies only to the F3.5 lenses, i.e., the 35mm wide-angle,
95mm and 125mm telephoto lenses.
•
The Electric Eye mechanism functions only when the
aperture control ring is set at "EE".

Coupling Range of the Electric Eye
The Electric Eye couples to the following range of f/stops
and shutter speeds with respective film speeds. When using
the 50mm standard lens and ASA 100 film, for example,
the Electric Eye couples fully within the range of f/l.S
at l/S sec. and f/16 at 1/500 sec.
•
The Electric Eye does not function at " 8" of the shutter
speed di al because "8" is used for indefinite timed exposures.
• When the Electric Eye is outside the coupling range,
the exposure indicator will point to the over/under exposure
warning mark,
and will indicate that proper exposure cannot
be obtained.
