Nikon PC-E Micro NIKKOR 85mm f/2.8D Manuel D'utilisation page 28

When using other Nikon cameras
a
Set the shift and tilt amount to 0 by rotating the shift
and tilt knobs. (Fig. 2)
b
Set the camera's exposure mode to M.
En
c
Press the aperture stop-down button to fully open the
aperture, set the aperture ring to "2.8" (maximum
aperture), and set the shutter speed for correct
exposure.
d
Set the desired aperture by rotating the aperture ring
and shift the shutter speed by the same number of
changed steps.
• Setting the aperture ring to minimum aperture lock (L)
fixes the aperture at f/32 (minimum aperture). (Fig. 6)
• Set the aperture with the lens' aperture ring even on a
camera that requires aperture to be set via its command
dial. With a camera that has the custom setting menu
"aperture setting with lens' aperture ring," this setting
is not required.
Determining exposure (with an external exposure
meter)
a
Set the shift and tilt amount to 0 by rotating the shift
and tilt knobs. (Fig. 2)
b
Set the camera's exposure mode to M.
c
Set the desired aperture using either the lens aperture
ring or the camera's command dial, input the aperture
value on the camera's LCD panel to the external
exposure meter to determine exposure, and set the
shutter speed. If you cannot read the aperture value on
the camera's LCD panel or cannot determine exposure
because the camera does not have an LCD panel,
choose a shutter speed appropriate for the f-number
(p. 256). With this lens, the brightness of the image on
the film (image sensing device) will decrease by 1 stop
and the effective f-number will increase by 1 stop at the
closest focusing distance.
