Film plane indicator

The film plane indicator

(-e-)

is engraved in white

the

top deck just behind the shutter

speed

dial. It indicates

the exact position of the film plane inside the

camera.

Whenever

it becomes necessary to measure the exact

distance

between the

subject

and film plane, such as in

macrophotography,

use

the film

plane indicator. The

distance

between the film plane

and the

lens mounting

flange@

is exactly 46.5mm

Infrared focusing index

When you shoot infrared

film

note that

the

plane

sharpest

focus is

slightly

farther

away

than that

visible-

light photography. As

rule of thumb, you can com-

pensate

for

this

shift

focus by referring to the infrared

compensation

index

(in the

form

of either

a red

dot

red

line)

near the

focusing index on

the lens

barrel.

(Some lenses, including the

Reflex

Nikkor, do not

need

compensation. )

After

focusing

the

image sharply through

the viewfinder,

check the

focused

distance

and turn the

focusing

ring to

the left until the

red infrared

compensation

index

lines

with the prefocused distance.

sure to shoot with

the

appropriate

filter,

such as

R60,

etc.
