Stop-down exposure measurement
Full-aperture exposure measurement is not possi-
ble with
the following lenses and accessories.
either because the lenses nave no auto diaphragms
or because the diaphragms will not couple with the
meter. Therefore, the stop -down method of
measuring exposure with the lens aperture dia-
phr agm manually stopped down to the taking
a
perture must be user! . First , push the coupling pin
as far
to the right as it will go. Mount a lens or
lens/accessory setup to the camera and switch on
the meter .
Auto lenses without coupling prong
With automatic exposure control: Use the depth-
of-fiekl preview button to stop down the lens and
turn the aperture ring until the black needle is in
the shutter-speed scale (Take note of the meter's
EV range).
With manual override: Use
the same procedure as
above.
Then turn the shutter -speed dial until the
green needle matches the black one. At manual
setting, pressure
on the depth -of-field preview
button is no longer necessary since the correct
exposure is set mechanically.
Caution: Never advance the fi lm with the depth-of -field
preview
button in the depressed position .

coupling prong.
Preset lenses (e. g. PC-Nikkor 28 mm)
Set the shutter-speed dial at " A" and turn the aperture
ring until the black needle swings to an appropriate shut-
ter speed .
