PROPER CARE OF YOUR CAMERA

Storage of Camera

Moisture

and

dust

are

harmful

to

your

camera.

It

be

taken

out

into

the

air

from

time to time.

If

your

is

to be stored

for

a

long

time,

it

should

be

removed

from

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.

contact of the mercury bat insert, then screw the cover

not confuse the r’-fj Not only will the meter fail to function in case of re-

verse	insertion,		but the cover cannot be screwed
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.

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.

2. 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.

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.

10

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:

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.).
