ALens Types
When using a CPU lens equipped with an aperture ring ( 0422), lock 
the aperture ring at the minimum aperture (highest f-number).
 Type G 
and E lenses are not equipped with an aperture ring.
When using non-CPU lenses ( 0229), select exposure mode  g 
(aperture-priority auto) or  h (manual).
 In other modes, exposure mode 
g  is automatically selected when a non-CPU lens is attached ( 0419, 
424).
 The exposure mode indicator ( e or  f) will flash in the control 
panel and  A will be displayed in the viewfinder.
ADepth-of-Field Preview
To preview the effects of aperture, press 
and hold the  Pv button.
 The lens will be 
stopped down to the aperture value 
selected by the camera (modes  e and  f) or 
the value chosen by the user (modes  g and 
h ), allowing depth of field to be previewed 
in the viewfinder.
ACustom Setting e5—Modeling Flash
This setting controls whether the buil t-in flash and optional flash units 
that support the Nikon Creative Lighting System (CLS;  0428) will emit 
a modeling flash when the  Pv button is pressed.

information. Pv

e: Programmed Auto
In this mode, the camera automatically adjusts shutter speed 
and aperture according to a built-in program to ensure optimal 
exposure in most situations.
AFlexible Program
In exposure mode  e, different 
combinations of shutter speed and 
aperture can be selected by rotating the 
main command dial while the exposure 
meters are on (“flexible program”).
 Rotate 
the dial to the right for large apertures (low 
f-numbers) that blur background details or 
fast shutter speeds that “freeze” motion.
 Rotate the dial to the left for small 
apertures (high f-numbers) that increase 
depth of field or slow shutter speeds that 
blur motion.
 All combinations produce 
the same exposure. While flexible 
program is in effect, an asterisk (“ U”) 
appears in the control panel.
 To  r e s t o r e  
default shutter speed and aperture settings, rotate the dial until the 
asterisk is no longer displayed,  choose another mode, or turn the 
camera off.

In shutter-priority auto, you choose the shutter speed while the 
camera automatically selects the aperture that will produce the 
optimal exposure.
To choose a shutter speed, rotate the 
main command dial while the exposure 
meters are on.
 Shutter speed can be set

g: Aperture-Priority Auto
In aperture-priority auto, you choose the aperture while the 
camera automatically selects the shutter speed that will produce 
the optimal exposure.
To choose an aperture between the 
minimum and maximum values for the 
lens, rotate the sub-command dial 
while the exposure meters are on.
 
Aperture can be locked at the selected 
setting (0126).
ANon-CPU Lenses ( 0419, 424)
Use the lens aperture ring to adjust 
aperture.
 If the maximum aperture of the 
lens has been specified using the  Non-
CPU lens data  item in setup menu ( 0230) 
when a non-CPU lens is attached, the 
current f-number will be displayed in the 
viewfinder and control panel, rounded to 
the nearest full stop.
 Otherwise the 
aperture displays will show  only the number of stops (F, with 
maximum aperture displayed as  FA) and the f-number must be read 
from the lens aperture ring. Sub-command dial

h: Manual
In manual exposure mode, you control both shutter speed and 
aperture.
 While the exposure meters are on, rotate the main 
command dial to choose a shutter speed, and the sub-command 
dial to set aperture.
 Shutter speed can be set to “ p” or to 
values between 30 s and 1/8000s, or the shutter can be held open 
indefinitely for a long time-exposure ( A or &, 0 123).
 
Aperture can be set to values between the minimum and 
maximum values for the lens.
 Use the exposure indicators to 
check exposure.
Shutter speed and aperture can be locked at the selected setting 
(
0126).

AAF Micro NIKKOR Lenses
Provided that an external exposure meter is used , the exposure ratio 
need only be taken into account when  the lens aperture ring is used to 
set aperture.
AExposure Indicators
If a shutter speed other than “bulb” or “time” is selected, the exposure 
indicators in the viewfinder and control panel show whether the 
photograph would be under- or over-exposed at current settings.
 Depending on the option chosen for Custom Setting b2 ( EV steps for 
exposure cntrl , 0 315), the amount of under- or over-exposure is 
shown in increments of 
1/3EV, 1/2EV, or 1 EV. If the limits of the exposure 
metering system are exceeded, the displays will flash.

with exposure ( 0106).
 Nikon recommends using a fully charged 
battery or an optional AC adapter and power connector to prevent 
loss of power while the shutter is open.
 Note that noise (bright 
spots, randomly-spaced bright pixels or fog) may be present in 
long exposures; before shooting, choose  On for the  Long 
exposure NR  option in the shooting menu ( 0299).
