For automatic diaphragm lenses with no cou
pling ridge
AUTO:
Hold in the depth-of-field preview lever to stop-
down the lens diaphragm. Then, adjust the aperture ring
until the black meter needle indicates the desired shutter
speed. Trip the shutter with the preview lever fully
depressed toward the camera body until the completion
of the exposure. An alternative way is to use the built-in
memory lock function. In this case, after reading the
meter in the same method as mentioned above, use the
memory lock to freeze the reading (be sure the preview
lever is still depressed when “locking in’" the reading),
and then free the preview lever. Release the shutter
while keeping the memory lock depressed.
MANUAL:
Select the desired shutter speed, depress and
hold the depth-of-field preview lever, and while keeping
it depressed, adjust the aperture ring until the needles in
the viewfinder overlap.
You may free the preview lever before releasing the
shutter.
For fixed-aperture lenses such as Reflex-Nikkors,
photomicrography or astrophotography
AUTO:
As the lens aperture is fixed, no additional
control is necessary.
MANUAL:
Adjust the shutter-speed dial until the
needles in the viewfinder overlap.
For additional control of exposure in either mode of
operation, use ND‘ filters, or adjust the illumination,
or switch to a higher or slower speed film.
