STOP-DOWN EXPOSURE MEASUREMENT
28
With some Nikkor lenses, full-aperture exposure mea-
surement is not possible, either because the lens has no
automatic diaphragm, or because the lens does not cou-
ple with the finder's meter; with certain accessories, too,
lens/finder coupling is not possible, thus, preventing full-
aperture
measurement. However, the camera's Photomic
meter can still be used for
exposure
measurement via
the
stop-down
method. Before mounting the lens (or
accessory)
on the
camera
body, push the meter coupling
lever up
and
to
the
right; with this action, the lever will
remain locked up
for stop-down exposure
measurement
(to
release the lever
after
removing the lens/accessory,
push the release to the right
as
described in
"Coupling
Lever Lock/Release Operation" on page 39). After set-
ting the finder, mount the lens
or
lens/accessory com-
bination
on
the camera, switch
on
the meter by moving
the film-advance lever to the
standoff
position,
and
then
set the controls
for
correct exposure
as follows:
For automatic diaphragm lenses with no coupling ridge,
set
the camera
to
the desired shutter
speed;
then, depress
the depth-of-field preview button to
stop
down the lens
diaphragm
and,
while holding
the
button depressed,
adjust
the
aperture
ring until the center LED indicator
comes on. Be sure to release the depth-of-field button
prior to making the
exposure.
