STOP-DOWN EXPOSURE MEASUREMENT

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 built-in meter; with certain accessories,

too, lens/meter coupling is not possible, thus, prevent

ing full-aperture measurement. However, the camera’s

meter can still be used for exposure measurement via

the stop-down method. Before mounting the lens (or

accessory) on the camera body, lock the meter cou

pling lever in the up position, as described in “Cou

pling Lever Lock/Release Operation” on page 43; the

lever must remain up as long as stop-down measure

ment is being performed. After setting the lever, mount

the lens or lens/accessory combination on the camera,

switch on the meter by moving the film-advance lever

to the standoff position (or moving the shutter-release

button lock to the left), and then set the controls for

correct exposure as follows:

For fixed-aperture lenses, such as Reflex-Nikkor lenses,

choose the desired shutter speed operation mode (ei

ther automatic or manual selection) first. When auto

matic shutter speed selection is used, no additional set

tings are required; when manual speed selection is used,

adjust the shutter-speed dial until the meter needles in

the finder overlap. The exposure can additionally be

controlled via built-in or accessory ND filters.
