If you turn the film winding
lever until it stops, the
film is advanced one frame
and the shutter is set.
" Through the film winding
operation, the operating
mechanism of the mirror
and the automatic pre-
set aperture mechanism
of the lens are set at
the same time,
, When you wind the film
for the first time after
loading film, the lever
may slip , so wind once
more,

Exposure Counter Dial
As the film is advanced one frame , the ex-
posure counter dial advances one number
to show how many pictures have been
taken_ When the back cover is opened ,
the exposure counter dial automaticall y
returns to "5", the starting mark .
When the shutter release
button is pressed , the
mirror snaps up , the lens
is stopped down at the
same time to the pre-set
aperture and the shutter
is released . The winding

• If the film winding is not complete, the
shutter will not be released eve~ if the
shutter but ton is pressed . In such cases,
wind the lever once more .
• A cable release
can be . attached
to the sh utter
button .

The shutter and aperture opening decide the
exposure , and if the coupled expasure meter
is used, the correct exposure can be easily
set .
If the dial stops at B, turn
in the opposite direction.
If the dial stops at 1000,
turn in the opposite
direction.
• The dial cannot be
turned
between Band
1000 .
• The numbers on the
shutter speed dial are
the denominators for
such fractions of a
second as 1/ 1000 and
1/15.

• B is used for bulb exposure. The lens re-
mains open as long as the shutter button is
kept pressed. It is used for long exposure
of over 1 second .
• When time exposure is required , set the dial
to B, use a cable release with a lock and
lock the cable release during exposure .
• The 1/ 60 scale on the dial is concurrently
used for X flash synchronization. It is used
for speedlight ( electronic flash) photography.
The actual exposure time is the time of
speed light flash duration . (such as 1/ 1000,
1/ 500, see your speedlight instruction ) .
• Avoid setting the dial for an intermediate
speed other than calibrated . Turn the lens
automatic pre-set aperture ring to the required
aperture stop . This adjusts the light volume
and brightness of the photographic object.
Be sure to set the manual aperture setting
at the full opening .
Lens Aperture
Exposure ratio
• Leave the manual aperture setting at the
full - opening position .
• The ratio between the aperture and the
exposure volume is as follows, F 2 as the
standard:
11
.2 1

.41 1 .8 12.°12.81 (3 .5 ) 14.°15 . 618.°111 1161 22
• The aperture ring can be set at po s itions between
numbers.

The Super Canomatic lens is equipped with the
automatic pre-set diaphragm. Ordinarily, the lens
is wide open, but when the shutter is actuated, the
lens is closed down automatically to the pre-selected
aperture stop. When the shutter operation is com-
ple t ed, it automatically reopens to full aperture.
Automatic Pre-Set Diaphragm
This is the mechanism for adjusting the size of the
aperture which is automatically closed down. If
thi s ring is turned and set to the mark, the lens is
closed down to the pre-selected aperture stop for
the instant that the shutter is released.
Manual Aperture Ring
If this ring is turned , the lens can be opened or
closed without relation to the pre-selected aperture
stop. Through use of this ring, you can see the
actual sharpness of picture. When using the manual
aperture mechanism , always have the automatic
pre-set aperture ring at the full opening position,
otherwise internal automatic mechanism will be
strained.

Supe r Canomat ic Me chanism
Through this mechan is m, the opening and clo s ing of
the apertur e cannot be seen with the human eye
at high shut ter speed . However , t he mo v ement
can be seen w i th the eye at B or slow speeds .
The
larger the aperture number , (e.g. smalle r lens
opening ,) the less light w ill reach the film, as y ou
advance one stop on the aperture ring, the light
vol u me is reduced to one-half . Consequentl y, whe n
you stop down one stop on the aperture stop ,
double the exposure time . if you stop down two
stops , you must increase the exposure time by four
times . Positions between numbers on the aperture
ring can be used . Depending on the lens, this halving
of t he light volume does not effectively apply bet-
ween full ope n and the st op next to it (e. g. F 1.8
and F 2) Since t he Canonflex RM has a bu ilt-in

Preparations
Set the film speed indi-
cator to the speed of
the film being used. To
do this, lift up the outer
sensitivity ring of the
shutter dial and turn .
ASA Ind ica tor
. Only the outer ring of the shutter dial can
be lifted and turned. After 10 appears
in the indicator, the dial cannot be turned
any further to the right. If 800 appears,
the dial cannot be turned any further to the
left .
• The film speed is noted on the film box or
in the instruction included the film.

Deciding the shutter speed (1)
Set the desired aperture stop . Aim your
camera toward the object to be photo-
graphed .
Turn the shutter speed dial and align the
lens aperture reading with the needle .
Be sure to set the shutter dial to a click stop.
• When reading the light meter, take care
not to cover the photo-cell with the hand .
• The reading of the aperture stop is carried
out along the guide line .
Deciding the Aperture (2)
Set the desired shutter
speed as recommended in
the film instruction. Point
the camera at the object
to be photographed. Read
the aperture stop indicat-
ed by the exposure meter
needle and set the auto-
matic pre-set aperture ring
accordingly . Be sure to
read corresponding posi-
tion of the zebra pattern
edges .
• Positions between numbers on the shutter
speed dial cannot be used, but positions
between numbers on the aperture ring
can be used. Consequently, in the strict
sense of correct exposure, it is strongly
recommended to set the shutter speed
first and then adjust the lens aperture
accordingly.

Zero Adlustment of Exposure
Adjust the exposure meter so that the needle always
points to "0 " when the photo-cell is covered .
Adlustment Angle
Adlustment Method
1. First , turn the zero adjustment cover
to the left and remove ( easily
possible if a rubber plate is used .)
2. An adjustment pin with a groove
can be seen in the hole, so use a
screwdriver or stick to turn the
pin to the left or right so that the
needle points to "0 ".
During this operation , the photo-
cell must be completely covered.
• When the background of the object being
photographed is very bright as in the case
of blue sky, there is the tendency that the
main object being photographed will be
under-exposed if the photo-cell is faced too
far upward . When reading the exposure
meter, it is necessary to avoid the camera
from tilting upward .
• When shooting against the light, it is important
to decide which to emphasize , the background
or the main object, in order to determine the
exposure .

The camera can be in the
positions shown in the
photographs on the right,
depending on whether you
are taking vertical or hori-
zontal pictures . While
looking through the finder,
focus and decide the com-
position of the picture and
then press the shutter
button.
At this time, the following
points are particularly im-
portant :
1.
Grasp the camera as
deeply as possible with
both hands.
2. Steady the camera
against either the cheek
or forehead .
3. When taking a horizon-
tal picture, have both el-
bows tight against the
body. When taking a
v' ertical picture, have at
least one elbow tight
against the body .
Pressing
the shutter button
roughly will result in shaking
the camera and blurred
pictures .
it
is best to use a tripod
and a cable release. This
is particularly true when
shoot ing at speeds slower
than 1/ 30 sec .

Remove the lens cap
and look through the
finder. Turn the focus-
ing ring.
When the picture in
the circle in the finder
is split in two by the
center line, then the
object is out of focus.
The object is in focus
when the image seen
in
the center aligns
vertically .

• Almost entire picture that will appear on the finished
film can be seen in the focusing glass, so there will
be no parallax even if the lens is interchanged or the
distance is altered.
• When focusing, disregarding the split-image method
for special effects or under a certain required situa-
tion, focus the subject on the part outside the circle.
• A waist-level viewer can be attached to the eye-level
finder. The waist-level viewer is best suited for ultra
telephoto lens, copying work and microphotography.
4kinds of adjustment
eyesight lenses are avail-
able for CanonAex RM.
It is recommended to a-
dapt suitable one for
those who wear glasses.
They are +1. 5,0, -2.5,
-4 .

Either daylight loading film (film in cartridge ) or
film looded in special Canon magazine V can be
used.
1. Turn up the back cover
ope~ng key and make a
half-turn to the left.
The film magazine cannot be
inserted unless the opening
key is in the complete open
position.
2. The back cover will
float up slightly, open door
completely the rest of the
way by hand.
3. Lift up the rewind crank
and pull out the rewind
knob completely .

4. Pull out the end of the
film and insert fully into the
film take-up spool. While
turning the flange of the
spool slightly in arrow direc-
tion, hook the protuber-
ance on the groove side
with the perforation of the
film.
5. At this stage, have the
both sides of film perfora-
tions accurately fit the teeth
of the sprocket. Also, if
there is slack in the film,
turn the rewind crank slow-
ly to the right to remove
the slack.
6. Close the back cover.
While holding down the
bock cover, turn the back
cover opening key to the
right. The rewind crank
should be folded.
7 . Keeping the lens cap
on, wind the film and re-
lease the shutter twice .
8. The exposure counter
dial will be at the S ( starting
point ) position, but after
two blank shots , it will in·
dicate o. The camera will
be ready for taking pictures
when you wind the film for
the next shot, i.e. film
counter at No.1 position.
