To use

the Memar

as

a

fixed

focus

camera,

set

the

focusing

ring

at either

10 or

30

feet

(the

numbers

in

red)'

Then

set

the diaphragm

ring

at

the red

dot on

the

diaphragm

aperture

(f

stop)

scale

and the

shutter

at

1/50th of

a

sec-

ond.

With

the

camera

focused

at

10 feet,

everything

from 7

to

15

feet will

be in

focus:

at

30 feet,

everYthing

from

15

feet to

infinity

will be

in

focus.

Sharpest

pictures

of

any specific

sub-

ject

will

result, of

course,

if

the lens

is

focused

at

the exact

camera-to-subject

distance.

the

diaphragm

The

diaphragm,

or

Iens oPening

as it

is often

called,

governs

the

amount

ot

Iisht

which

passes

through

the

lens

while

the shutter

is open.

The

diaphragm

opening

is set

by

turning

the

wide

dia-

phragm

ring

which

has

an index

mark

on

top.

Turn

this

ring so

the

index

mark

coincides

exactly

with

the line

opposite

the f

number on

the

diaphragm

aperture

scale.

As it

moves

from

the lower

num-

ber

(f,23.5)

to

the higher

(f/16),

the

size

of

the opening

decreases

and

the dia-

phragm

is

said to be

"stopped

down".

Remember,

the lower

the

number,

the

Iarger

the

aperture

and the

greater

the

amount

of light

admitted.

To observe

the action

of the diaphragm,

set

the

shutter

at B, open

the back

of

the camera

and

press

and

hold down

the

shutter

release button.

Looking

into the

back

of the

camera

toward

light, revolve

the diaphra8m

ring back

and

forth. No-

tice

how the size

of the

opening

varies.
