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)
En
b Set the camera's exposure mode to M.
c Set the desired aperture via the lens' aperture ring or the
camera's command dial and read the aperture value
displayed in the camera's LCD panel or selected aperture
ring value. Input the aperture value to the external
exposure meter to determine exposure, and set the
shutter speed.
• When using a camera other than the D4, D3-Series, Df,
D800-Series, D700, D610, D600, D300-Series, D90, D7100,
D7000, D5300, D5200, D5100, D5000, D3200, D3100 or
D3000, 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.
7. The shift/tilt function
Important
• Use of a tripod is recommended for correct shooting.
• Turning each knob too tightly can cause damage.
• Use of tilt/shift function can cause some vignetting.
(Vignetting is the darkening of the corners around the
image.) To counteract this, close the aperture (choose a
larger f-number), or compensate the exposure before
shooting.
• Determining correct exposure with shift and/or tilt use
requires experience. We recommend that you take a
series of test shots until you feel comfortable with the
operation.
