exposure
measurement
This exposure measurement method
is
used when the dia-
phragm
on
the lens does not link with the meter coupling lever
on the camera body, such as when a non-AI lens or
an
exten-
sion ring
is
mounted
on
the camera. The procedure
is
as follows:
1)
Set the
ASA
/
ISO
number.
2)
Compose your picture and·secure subject focus.
3)
Press the shutter release button lightly to turn the meter
on
.
4) Perform exposure measurement, depending
on
the type of
lens used:
• Lens with automatic diaphragm
Determine the correct exposure while pressi
ng
the depth-
of-field preview lever
® , then take your finger off the lever
and depress the
sh
utter release button.
• Lens without automatic d
ia
phragm (
PC
-Nikkor lens)
First, determine the correct exposure
by
adjusting the
shutter speed and aperture. Then, focus at full aperture.
Shift the lens so that you get the desired composition.
Re-
turn the aperture setting to the preset po
si
tion and shoot.
• Lens with fixed aperture (Reflex-Nikkor lens)
Exposure cannot
be
changed according
to
the aperture be-
cause
in
this type of lens, the aperture
is
fixed. Determine
the correct exposure
by
turning the shutter speed dial. If
correct exposure is unobtainable, use
an
ND
(neutral den-
sity) filter or change the illumination
to
adjust the exposure.
