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

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.).

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

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

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.

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

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
