Your CANON CAMERA and CANON LENS are the praducts of the highest
grade of precision engineering and optical research.
The camera is sträng, compact and simple ta operate. As it is a precision
instrument, it is advisable that you understand how to operate it by
studying the direction carefully.

The superior resolving power of the CANON LENS will produce negatives

of extreme sharpness; the lens will resolve to a higher degree than the
emulsion of modern high-grade film.

• USE YOUR CAMERA INTELLIGENTLY

• LEARN TO USE IT IN EVERY POSSIBLE WAY

• TREAT IT WITH RESPECT
Although fully guaranteed for five (5) years, it will, with care, last you
a lifetime and give you photographs you will be proud to own.

HOW TO OPERATE YOUR CATION CAAiERA

1. Remove the Lens Cap. By sure to replooe this Cap when your comero is not in use.

2. See that the Reversing Lever is at the "A" (Advance^ position.

Then turn the Film Winding Knob one complete turn when it will stop By doing so you

will advance one film frame and wind the shutter ot the same time,

NOTE: Always wind the Film Winding Knob just before taking a pi:ture. Do not leave it wound

L

over long periods as this may weaken the Shutter Spring and may cause accidental exposure if
the Shutter Release Button is pressed by mistake.

Setting The Shutter Speed Dials

There are two Shutter Speed Dials:

fnJet: Msrk

High : for speeds between 1

(1/500 sec. on Model I

Slow : for speeds between

T (Time)

/25 to 1/1000 sec,
l-D)& B (Bulb)

1 '25 to 1 sec. &

High Shutter Speed Dial

Correct exposures ore best obtained with on exposure meter or by following the instruction
supplied with the film.
To operate the camera at any of the speeds shown on the High Shutter Speed Dial, first
turn the Film Winding Knob. Raise the dial with thumb and forefinger and turn until the

speed required is exactly opposite the Index Mark and let the dial fall. For 1/1000 sec.,

the dial drops only half the distance of the other speeds. Intermediate speeds can not be used.

N0TE: When the High Shutter Speed Dial is in use the Slow Shutter Speed Dial must be set at 25

{l/25 sec.).

A

Slow Shutter Speed Dial

The Slow Shutter Speed Dial will offer speeds between 1/25 to 1 sec. and T (Time) by
turning the dial to the correct position so that the required speed registers uppermost
opposite the index mark. The Dial is locked only at 25, to release it press Spring Lock
with your thumbnail and turn the Dial to your left. Be sure that the High Shutter Speed
Dial is set at 25-1 (1/25 sec.).

NOTE: Speeds intermediate between l/25, //d, //4, //2 and I sec. may be obtained by setting the dial

to the estimated position.

Time Exposures Longer Than One Second

A time exposure may be obtained by using the B (Bulb) position
on the High Shutter Speed Dial. The shutter remains open
from the time you press the Shutter Release Button until the
pressure is removed.
You may olso obtain a time exposure with the Slow Shutter
Speed Dial or T (Time). Press the Shutter Release Button and

the shutter will open and remain open until you turn the
Slow Shutter Speed Dial to 1. The shutter will close only
when this method is used.

NOTE: For speed slower ihen I/25 sec. a solid tripod is essential,
and preferably a Canon Camera Holder and Canon Cable Release.

Lens Aperture Scale

The Lens Aperture controls the amount of light entering
the lens and also the Depth of Field. Set ih« Letrs

Aperture (f-stop) by turning the Aperture Scale i.knurled
ring) to the proper position. This is best determined

with an exposure meter or by following the instructions

given with the film.
When the Lens Aperture is closed by one stop; the
amount of light entering the Lens is decreased by one
half, two stops, by one quarter and so on. Therefore

you should adjust the Lens Aperture in conjunction
with your shutter speed. Suppose your exposure meter
indicates a speed of 1/200 sec. at f : 5.6. If you want
to expose for a slower speed say 1/100 sec., then you
must close down the Lens Aperture to f ; 8. In other
words, as you have doubled the time of the shutter
opening, you must reduce the amount of light entering
the lens by half to obtain the correct exposure.

Knurled Ring

r

Depth of Field Scale

The Distonce Scale and the Depth of Field Scale are used
together.
Depth of Field means the range of objects which will be in
focus on your film. This range varies with the distance of the
object of sharp focus and the Lens Aperture. It extends from
in front of the object of sharp focus to beyond it. The
greater the Lens Aperture, the less will be the Depth of Field.
Depth of Field also diminishes as the distance of the object
of sharp focus from the film plone decreases.
The illustrotlon shows the Lens Aperture at f:1.8 and the
Distance Scale at 25 feet. An object at 25 ft is in sharp focus.
The Depth of Field Scale shows that the nearest object also
in focus is approximately 21 feet and the farthest object in
focus is approximately 30 feet. If the Lens Aperture Scale is
set at f : 11 the object in focus will extend from 12 feet to
infinity (to). See illustration on next page.

Infrared Index

R marking indicates the position at which focusing should be set when using an

infrared film. Be sure to use proper infrared filter which is reco.mmended by
manufacturer of infrared films, After accurate focusing is done in the usual man
ner read the object distance off the Distance Scale of the lens. Then turn the lens
so that the object distance will be exactly opposite the R index mark. The lens is
now in focus for infrared photography.

Index Marie

Distance Scale

When accurate focus (see page 10) has been
made on any object, the actual distance
from the film* to the object is shown by
the Distance Scale which is marked from

3.5 to infinity (oo) in feet. Lenses with metric
scales are provided when specially ordered.

*Shown by fhe Red Doi near the Accessory Clip.

Focusing

If is recommended that the camera be held as illustrated. It should rest comfortably on
the heel of the left hand and be balanced by the right hand. Hold the camera to your
cheek to keep it steady while sighting through the Range-View Finder* Eyepiece. Manipulate
the Focusing Lever with either your left or right forefinger whichever is more comfortable.
More precise focusing is possible by setting the Magnification Control Lever at 1.5 x (see

page 12) and rotating the Milled Focusing Ring as shown in right illustration.

NOTE: The Focusing Lever is released from the infinity Catch on the lens by depressing the knob and

turning. » JPN. PAT. 176637 175722

10

In correct focus

As you look through the Range-View Finder Eyepiece and rotate the Focusing Lever you

will see two images of the same object. The images move apart or together as the lever

is rotated. Turn the Focusing Lever until the two images of the object on which you are
focusing coincide exactly. Your lens is now in sharp focus on the object. At the same time
all objects in the range shown on the Depth of Field Scale will also be in focus at the
f-stop you select for the exposure.

1 1

Magnification Control'

There are three positions for the Magnification Control Lever;
F, lx, and 1.5x. When really sharp focusing is required,
turn the Lever to 1.5x when the object will be magnified 1.5
times. Remember, however, the actual image recorded on the
film will be the picture seen at the F position of the Lever.

The lx position corresponds to the image seen and recorded
by any CANON LENS with a focal length of 100mm. The 1 .5x
position shows the image for any CANON LENS with a focal
length of 1 35mm.

A certain difference between the picture seen through the

Range-View Finder Eyepiece and the image recorded by the
lens is inevitable. For normal photography the difference is immaterial being so slight.
But for certain work compensation should be allowed.

JPN PAT. 379444

12

When the Lever is set at lx for CANON
LENSES with focal length of 100mm, and the
object distance is less than 13 feet a special
viewfinder with parallax compensation adjust
ment should be used.

NOT£: Specially designed Viewfinders to
compensate for parallax are available for all
CANON LENSES except for the Standaid
50 mm CANON LENSES.

At 1 .5 X with 135 mm CANON LENSES for
distance less than 14 feet it is essential to
use the special viewfinder available for each
type of lens

13

Exposure & Composition

To expose and compose your picture are the lost steps
and perhaps the most important. Be sure lhat the main
object in the scene you are photographing is in sharp
focus,

For 50 mm CANON LENSES, the image recorded on the
fìlnì will be the one seen through the Eyepiece with the
Magnification Control Lever at " F Having composed
your picture gently press the Shutter Release Butlon with
your forefinger. Never jerk while making an exposure.
The slightest movement foi an exposure made at 1 25 sec.

or slower will give you a bluried picture
By pressing the camera to your cheek, keeping your

elbows into your side and by holding your breath just

before and duiing the actual instant of exposure you
will get ail extiemely shai p pictuie.

Theie are two ways to liold the camera. One is for
horizontal pictures as shown in this page and the other
is for verticol pictures as shown in next page,

14

NOTE: Make sure your finger does not touch the High

Shutter Speed Dial as it will alter the correct speed.
Give particular attention to this when gloves are

NOTE: When taking vertical picture care should be taken

that the cover does not swing in front of the
lens, lb is recommended to detach the flap from
the case.

16

Double Exposures

Double exposures are normally quite impossible on the CANON CAMERA, but for
special effects they are sometimes needed. Expose the first picture as usual. Then
while keeping the Shutter Release Button pressed down, turn the High Shutter Speed
Dial COUNTER-CLOCK-WISE without lifting the Dial until you hear a "Click” and the
Dial turns no further. Release the Shutter Release Button first then the Dial. The
Shutter is now completely rewound and the second exposure may be made.
This action may be repeated any number of times, and be adjusted to another

speed, if required.

The Take-up Spool has a spring catch to facilitate

its easier removal from the camera body. By turning
the top of the Take-up Spool slightly, it v/ill jump up

and allow you to get a better grip. Re-lock this
spring as shown in the illustration after you have
loaded your camera and before you replace the
Baseplate.

Replace the Baseplate by hooking it into the
lug first and lock the Baseplate.

21

Keep the Reversing Lever still
at '"A". Pull up and turn the
Rewinding Lever gently in the
direction shown by the arrow
in the diagram. When it will
not turn further, your film is
taut, having taken up the
slack film in the magazine.
Lastly, turn the Film Winding
Knob and press the Shutter
Release Button. Repeat this
process once again. By doing
this you ensure that you will
not use the first two frames
which have been exposed to

light while you were loading.

See note on page 23 to verify

that you have correctly loaded

the film.

Next set the Exposure Counting
Dial at the base of the Film Wind

ing Knob to "1" by turning it

counterclockwise with your thumb

nail catching one of the lugs on
the Dial. Each time the Winding

Knob is turned this Dial automa
tically registers the next number.

22

Next set the Film Speed Indi
cator* at the top of the Film

Winding Knob to the speed of
your film. This will serve as a
reminder that your camera is
loaded and will show speed of

the film you are using.

23

« JPN. PAT.

NOTE: Each time the Winding Knob is turned the

Rewinding Knob rotates in a reverse direction.

This indicates that the film is properly

passing to the Take-up Spool for the next

exposure, provided you have taken care to
make the film taut by tightening the film
wound in the magazine. Should the Rewind
ing Knob not turn, obviously the sprockets
are not engaging the film perforations. You
should then rewind the film until it disengages
the Take-up Spool, open the Baseplate and
reload again.

STOP THE REWINDING MOTION (SEE NEXT PAGE) AS SOON
AS THE REVOLVING OF THE SHUTTER RELEASE BUTTON
CEASES. THIS WILL PREVENT THE LEADER FROM DRAWING
COMPLETELY INTO THE MAGAZINE.

Unloading

When the Film Winding Knob no longer turns, you
have come to the end of your film roll. DO NOT
FORCE IT. Make sure to release the shutter first
and then turn the Reversing Lever from '"A" to "'R"
(Rewind). Raise the Rewinding Knob and rewind the
whole film back into its original magazine. When
you have done this, you may open the Baseplate
and take out the flm magazine. The film is now
ready for developing.

During the rewinding operation the Shutter Release
Button turns and stops the moment the film leader is
pulled off from the Take-up Spool, Rewind a few

more turns so that the leader will be drawn com

pletely into the magazine.

BRIEF HISTORY OF CANON CAMERA COMPANY, INC.

Canon Camera Company, Inc. was first established as a Research Institute in the year of 1933 for the objacLi\’e of
studying and manufacturing the very best miniature cameras in Japan. In 1935, through intensive researches and

designes, the first model named as “ Kannon ” Goddess of Mercy! was produced and put on market with pride

and confidence under the trade name “CANON”.
Very little number of cameras were being produced during the early stage but continued efforts have been made

to improve the quality and to increase the production as well as to put out variety of accessories for Canon cameras.
Canon Camera Company, Inc. is now equipped with various superfine precision machineries, testing instruments,

and operated by a number of top grade engineers, technicians, and designers. Lifelong experience and natural skill
of these staff enable the company to fabricate the entire works within the company. Optical glass dissolving,
lens polishing as well as shutter and metal assembling are all done through modern steamlined operation.

I.enses produced by Canon Camera Company, Inc. have been called “SERENAR” but they are now named as
“CANON LENSES”.

Canon Camera Company, Inc. is the largest camera manufacturer in Japan with the longest history and the greatest
reputation.
