PROPER CARE OF YOUR CAMERA

Storage of Camera

Moisture and dust are harmful to your camera. It should be taken out into the fresh air from time to time. If your camera is to be stored for a long time, it should be removed from its case. Silica gel or another drying agent should be placed along side it.

^ □

Cleaning of the Camera

When you use your camera on a rainy day, or

at the beach, moisture and salt air adhere to it, which can result in stains, rust, and corrosion. Use a soft brush to rid the body of dust and

a dry, soft cloth for wiping.

Cleaning of the Lens

Use a blower with a rubbur ball to blow away dust on the lens or brush lightly with a brush. Do not touch the lens. If you should inadvertently get a finger print on your lens, follow this procedure : use a little pure alcohol or ether, if available, on

special lens tissue. Then wrap the tissue around a wooden matchstick and wipe the lens in a cir cular motion. . . lightly and systematically.

• In extremely cold areas, expose the camera to the outer air only when in use. Put it back im mediately after use. When using, expose the camera gradually to the outer air to prevent the lens from clouding.

MERCURY BATTERY LOADING

Load the mercury battery into the battery com partment. Since the mercury battery powers the built-in CdS meter, the meter will not function unless the battery is in position.

1. To remove the battery cover, turn to the left by using a coin.

2. Face the central tery inwards and back in.

When inserting, do only will the meter fail to function in case of re-

contact of the mercury bat

insert, then screw the cover

not confuse the r’-fj Not

verse insertion, in properly.

For mercury battery, the National M ID or the Toshiba TH MC is used—equivalent to the United States Mallory RM-625R, Eveready E 625, GE :625. Life of the battery in continuous use is over one year. Before insertion, clean mercury battery thor oughly with a dry cloth. Perspiration or finger marks may cause corrosion and may prove particularly harmful to center of contact. Un clean battery may also damage the contact point of camera. When not in use for a long period, remove the mercury battery and keep in a dry place.

but the cover cannot be screwed

Battery Check

Check the mercury battery after loading it. Es pecially when loading a new battery, be sure to check the voltage.

1. Turn the revolving switch to match the “C” indicator.

2. Check the efficiency of the battery by reading the meter needle. Voltage is sufficient if the needle swings to the right side within the blue colored section. If the needle stops on the left side, the battery must be replaced.

FILM WINDING

Turn the film winding lever until it stops. The film will be advanced to the next exposure and the shutter cocked. At the same time, the exposure counter dial is advanced to the next number.

When the shutter button is pressed, the film

can be wound again with the lever after the

shutter is actuated.

• Before winding the lever, be sure to return the film rewind ring index to the “A"

position. The winding may be done by moving the

lever with several short strokes. After loading the film, make another wind, since there is the possibility of the very first winding not catching. Unless the winding is completed, the shutter will not be actuated, even though the shutter button is pressed. Check the winding once more. When the camera is not in use, return the

lever to its original position against the body.

Shutter Button Safety Lock

If you put the index of the rewind ring on the red dot after the shutter is cocked, the shutter button is locked. This is an added safety device when carrying the camera with shutter cocked. This also enables you to attach the cable release after the shutter is cocked without fear of actuating it.

Exposure Counter Dial

The film is advanced whenever the film winding lever is completely wound and the exposure coun ter dial is advanced by one number indicating the number of exposed films. The exposure coun ter dial returns to starting position "S” auto matically when the back cover is opened.

Attaching the Cable Release

A cable release can be attached to the shutter button.

SHUTTER AND APERTURE ADJUSTMENT

Exposure adjustment is done by adjusting the

shutter speed and the lens aperture. Correct exposure is easily determined by the coupled, built-in exposure meter.

How to Set the Shutter Speed

Turn the shutter speed dial and set the desired shutter speed figure to the index mark. The shutter can be adjusted to speed of 1 second, 1 2, 1 4, 1 8, 1 15, 1 30, 1 60, 1 125,

Make reverse turn when

it stops at X.

Make reverse turn when

it stops at 1000.

The dial cannot be turned between 1000 and X.

1 250, 1 500, and 1 1000 of a seconds as well as “B” (bulb) and "T” (time) exposures and "X".

The “B” exposure is used for exposures of over

1 second. The shutter stays open as long as

the shutter button is kept depressed. The "T” exposure is used for long exposure.

When the shutter button is pressed, it will remain depressed, even after your finger is removed,

leaving the shutter open. By turning the shutter speed dial slightly in either “B” or "X” direction, the shutter button snaps back into its former position and the shutter closes.

The “X” scale reading is used for speedlight synchronization. The shutter speed is 1 '60 of a second. However, the effective time of the ex posure in this case depends on the peak perform ance of the speedlight used.

•

• Do not set the shutter speed dial between two figures. It must be set exactly on a

“click” stop.

How to Set the Lens Aperture

The lens aperture adjusts the light volume that reaches the film and also the depth-of-field. (See page 35.) The desired aperture stop can be obtained by turning the lens aperture ring until the figures align with the index mark. Canon 7S, by using the built-in meter, can easily determine the lens aperture which sets the shut ter speed.

• In the case of the aperture, as the numerical value gets larger the amount of light reaching the film becomes correspondingly less. For

each aperture, the light is reduced one-half. Accordingly, when the aperture is increased by one index point, the exposure is doubled, and when it is increased by two index points the exposure is quadrupled. The lens aperture ring can also be set to intermediate values. The ratio between aperture and the amount of exposure, using F 2 as the basis, is as follows : Lens Aperture

0.95 1.2 1.4 1.8 2 2.8(3.5)4 5.6 8 11 16 22 Exposure Ratio 1'4 1 3 1 2 1/1.2 1 2 (3) 4 8 16 32 64 128

BUILT-IN EXPOSURE METER

The Canon 7S Exposure Meter, which is the match-

needie type, is coupled to the shutter dial. The

exact exposure may be easily determined accord

ing to the brightness of the subject to be photo graphed. There are two ways of determining the exposure, either by first selecting the shutter speed or by first selecting the lens aperture.

Preparations

1. Show the film speed of the film used in the small window. To do this, turn the shutter

speed dial while pressing the film speed in dicator button.

• When ASA 6 appears in the small window, this is as far as it will turn to the left. The right turn extremity reads 400.

• The following film speeds may be used:

2. Turn the switch to ON.

3. Determine the meter sensitivity. In ordinary brightness outdoors, turn the sen

sitivity shifting knob to match "L" for low sensitivity use. Make adjustments to "H" for indoors or outdoors just before sunset.

• The sensitivity of the meter is based on a two-stage high and low system. For low sensitivity (bright subject), the setting should be EV 10-19 IF 1.4 1'500 sec.-F 22 1 1000 sec.). For high sensitivity (dark subject), the setting should be EV 2-11 (FI 1,4 sec.-F 2

1 ,'500 sec.).
