at

the bottom

of

the Finder

to

a position. so

that

the figure

appears

in

the

aperture

window

on the bock

of

the Finder.

Then, mount the Finder

onto

the camero

fits the

groove

on the selectOf. The

selector

can

be

turned

together

with

the

EXPOSURE

MEASUREMENT

Full-aperture

measurement

The Photomic-T Finder

is

so ingeniously designed that,

so

for

as

the lens

is

coupled

to

the Finder

with

the

prong,

the

exposure

can be

determined

with

the

aperture

of

the lens

fully

open, no

consideration

being

required

as

to

the

pre-selected

aperture,

to

take

advantage

of

using the

"Auto"

lens,

which

permits

getting

view

of

the

brightest

nnder

image

in

focusing and composing.

Stap-down

measurement

When

a lens

which

is

not

provided

with

the coupling

prong

or

when

the

coupling

is

prevented

by

any

intermediate

attachment

between

the lens and the camera, the

ex-

pcsure setting should

be

made

with

the

operture

of

the lens

stopped

down

to

the

aperture

actually

being

used Isee p.

191.

[]

ORDER

OF

USING

THE

FINDER

The

use

of

the Finder proceeds

in

the

following

order

:

1)

LENS

APERTURE

Be

sure that the speed (ASA)

of

the film being used

is

_set

to

the max. aperture

of

the lens. If

it

is

not, turn the

DIm

speed

(ASA) dial

on

the top

of

the shutter speed selector,

using

two

pins,

so

that the film speed (ASA) lines

up

with

For

example, the

DETERMINING

THE

EXPOSURE

First, depress the side button

so

that the top button pops up,

showing a red band around.

The

red

color

will

serve

to

arouse

attention.

Viewing the finder field,

rotate

the shutter speed selector

and/or the aperture ring

of

the lens, until the pointer needle

inside the viewfinder

The

needle moves

in

the

same

direction

as

the shutter

speed selector and the aperture ring rotate.

The

meter

pointer needle

is

also visible

in

the outside top

window.

The

camero

is

now

ready

for

taking picture

of

the

subject.

11

12

IMPORTANT!

•

After

the camera

has

been used, depress the

tgp

bUllon so

that the side bUllon pops up,

to

avoid

unnecessary

drain

of

the mercury

ballery.

•

The

shuller speed

selector

clicks

at

each marked

selling.

The shuller does

not

give

an

intermediate

exposure time'.

Therefore,

if

the

needle

does

not

come

exactly

to

the

center

at the moment the shUller speed

selector

clicks,

correct

the

deviation

of

the

needle

by

slightly

revolving

the

aperture

ring

of

the lens.

•

When

the

needle

comes

to

the

center

at

B·2

selling

on the

shuller

speed

selector,

the COrrect exposure time

will

be

2 seconds. Depress the

sh

u

ller

bu"

lOn

for

2 seconds

at

the B·2 position.

In

this exposure,

use

a

tripod

to

avoid

camera movement.

T-exposure cannot be made

with

the Photomic-T Finder mounted on the camera. For

this purpose,

use

the B-2

selling

and a

cable

release.

[]

USING

FILTER

OR

ClOSE-UP

ATTACHMENT

It

is

one

of

the

great

advantages

of

the Photomic-T Finder

that

the exposure

factor

need

not

be considered

in

using-a

rllter

or

close-up attachment lens

attached

on the

lens, because the

exposure

decrease

caused

by

it

will

give

the same

effect

to

the

meter

and

to

the film. The

correct

exposure

is

always

obtained

by

the

meter

setteng

wit

ho

ut

any

alteration.

For the same reason, the adjustment

of

F-number, which

is

required

when

the lens

is

extended

for

close-ups

such

as

in

the case using

an

extension ring

or

bellows,

can

be

disregarded

.

In

these cases,

however,

it

is

necessary

to

observe the

order:

.Set the

exposure

after

focusing.

It

is

also important that no

picture

should be taken

with

the

filter

removed

after

the exposure

is

set

with

the

filter

attached.

13

n

BRIGHT

OR

DARK

SCENE

14

The

Photomic-T Finder measures the average brightness

over

the entire image

area

of

the finder. Therefore,

if

a subject

much

brighter

than-the main subject

is

included

in

the

finder viewfleld,

or

any bright

or

dark scene occupies a large part

of

the image field,

the measuring result

will

be incorrect.

For

example:

• Bright

sky;

snow;

white

wall;

sand

beach, etc. extending

over

one-thirds

of

the nnder

image area.

• Electric lamp; bright

window;

etc. illuminating

as

back light.

• Black

wall;

dark scene; etc. occupying one-thirds

of

the finder field.

Measurement should be made

by

slightly changing

direction

of

the camera

or

by

approaching

the subject, so that the aimed subject

or

scene

covers

a

large

part

of

the

finder

viewfleld.

DI

COUPLING

·

RANGE

OF

METER

It

may happen

that

by

an e

-1<

tremely

bright

or

dark scene, the

meter

needle

stops

or

make a discontinuous movement and con

not

be

set to the

center.

This

does not indicate

any

disorder

but the

fact

that

the brightness

of

the scene

is

out

of

the coupling range

of

the

meter.

For example, when using a lens

of

F/

1A

and a film

of

ASA

100, a

brightness

over

the

aperture

Fj22

at

the shutter speed 1/

500

sec.

or

under F/1A

at

sec.

will

not

be within. the coupling range.

The same movement

of

the

needle

may

be

possible even

within

the coupling

range

when

the combination

of

aperture

and shutter speed

is

selected

too

far

away

from

the

correct

exposure

toward

the

opposite

limit.

In

this case, reset the shutter speed

to

1/15

or

1/60 sec. and

try

again the measurement, then the

correct

centering

will

be

obtained.

Note:

The least coupling brightness

var

i

es

with

the max.

aperture

of

the lens in

use

.

Therefore,

for

example,

if

the F/ 4 lens

is

replaced

with

the F/ 1.4 lens, a

brightness under F/ 4, 1

sec.

will

become

out

of

the coupling range

of

the

meter

.

INFLUENCE

BY

FINDER

SCREEN

16

Some types

of

the

finder

screens

exert

on

influence

up.:>n

the measuring result

of

the

meter.

To

compensate the influence,

change

the

fi

lm

speed setting

to

the figure as

shown

by

the number

printed

in

bold

block in fhe

table

Isee

opposite

pagel,

depending

upon

the

type

of

the lens

being

used.

However,

for

the lenses

of

small max,

aperture,

where

such adjustment

goes

beyond

the

lim

it

of

the max.

aperture

adju

stment,

it

must

be

made

by

decreasing

the

exposure

determined

by

meter

as

many steps as shown

by

the

red numbers in the

table,

the film speed

being

set

to

the max.

aperture

of

the lens.

For example,

when

using the lens

300

mm

F/

4.5

and the

finder

screen

type

H2,

the

necessary adjustment

will

be 1

liz

steps

wi

th the

fi

lm speed set

to

F/4.5. Then,

provided

the

meter

setting

is

obtained

with

the shutter speed 1/ 125 sec.

and

the

aperture

of

lens

stopped

down

to

F/

8,

change

the shutter

sp~ed

to

1/250

sec.

and

the

aperture

setting to t

position

ha

lfway

between

F/8 and F/

,

or

with

the

shutter

speed

unchanged

,

set

th

When

LIGHT

ENTERING

THE

EYEPIECE

FROM

BEHIND

18

As

the Photomic-T Finder is designed ingeniously

to

eliminate

an

objectionable

influence

of

light coming from behind the finder

eyepieces

,

there

is

no

need

of

worrying

about

such

an influence under the normal conditions. Under the special conditions

as

below

,

the

use

of

the

eyecup

on

the

eyepiece

is

recommended

so

os

to

avoid

as

much

as

possible the entronce

of

is

measured from the camera

located

When

it

•

When

on the camera top,

cover

the finder

with

the hand.

STOP-DOWN

MEASUREMENT

Some interchangeable

Nikkor

lenses

ot

extremely

long focus

and

other

special purpose lenses have no coupling prong on

their

aperture

ring. Even

when

they

are

provided

with

the

coupling prong,

they

ore

sometimes used

with

the prong

not

coupled, on account

of

the attachment inserted

between

the

lens and the camero,

such

as

the extension ring,

bellows

or

for

any

other

reason.

In

these cases,

proceed

as

follows

Set the film speed (ASA)
