P, S, A, and M Modes
P,  S,  A , and  M modes offer different degrees of control over shutter 
speed and aperture.
ModeDescription
P
Programmed auto  (0 48): Camera sets shutter speed and aperture for optimal exposure. 
Recommended for snapshots and in other situat ions in which there is little time to 
adjust camera settings.
SShutter-priority auto  (0 49): User chooses shutter speed; camera selects aperture for best 
results. Use to freeze or blur motion.
A
Aperture-priority auto  (0 50): User chooses aperture; camera selects shutter speed for 
best results. Use to blur background or bring both foreground and background into 
focus.
MManual  (0 51): User controls both shutter speed and aperture. Set shutter speed to 
Bulb ( A ) or Time ( %) for long time-exposures.
ALens Types
When using a CPU lens equipped with an aperture ring ( 0296), lock the aperture ring at the 
minimum aperture (highest f-number).
 Type G lenses are not equipped with an aperture 
ring.
Non-CPU lenses can only be used in modes  A (aperture-priority auto) and  M (manual), when 
aperture can only be adjusted using the lens aperture ring.
 Selecting any other mode 
disables the shutter release.
ANon-CPU Lenses ( 0295)
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 ( 0149) 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.

P: 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. This mode  is recommended for snapshots and 
other situations in which you want to leave the camera in charge of 
shutter speed and aperture.
AFlexible Program
In mode  P, 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, a  U indicator 
appears in the control panel.
 To restore default shutter speed and aperture settings, rotate 
the main command dial until the indicator is no  longer displayed, choose another mode, or 
turn the camera off.
AThe Shutter Speed and Aperture Displays
The shutter speed and aperture displays can be activated by pressing the shutter-release 
button halfway to start the standby timer ( 038).

S: Shutter-Priority Auto
In shutter-priority auto, you choose the shutter speed while the 
camera automatically selects the  aperture that will produce the 
optimal exposure.
 Use slow shutter speeds  to suggest motion by 
blurring moving subjects, fast shut ter speeds to “freeze” motion.
To choose a shutter speed, rotate the main 
command dial while the exposure meters are on. 
Shutter speed can be set to “ v” or to values 
between 30 s and 
1/8000s.
Fast shutter speed (1/1600s) Slow shutter speed (1/6s)

appear in the shutter-speed displays.

A: 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.
 Large apertures (low f-numbers) increase flash range 
( 0 123) and reduce depth of field, blurring objects behind and in front 
of the main subject.
 Small apertures (high f-numbers) increase depth 
of field, bringing out details in the background and foreground.
 Short 
field depths are generally used  in portraits to blur background details, long field 
depths in landscape photographs to bring the foreground and background into focus.
To choose an aperture between the minimum and 
maximum values for the lens, rotate the sub-
command dial while the exposure meters are on.
Large aperture (f/5.6) Small aperture (f/22)
ADepth-of-Field Preview
To preview the effects of aperture, press and hold the 
depth-of-field preview button.
 The lens will be 
stopped down to the current aperture value, allowing 
depth of field to be previewed in the viewfinder. 
ACustom Setting e5—Modeling Flash
This setting controls whether the built-in flas h and optional flash units such as the SB-910, 
SB-900, SB-800, SB-700, and SB-600 ( 0304) will emit a modeling flash when the depth-of-
field preview button is pressed.

M: Manual
In manual 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-co mmand dial to set aperture.
 Shutter 
speed can be set to “ v” or to values between 30 s and 1/8000s, or 
the shutter can be held open indefinitely for a long time-exposure 
(Bulb/ A  or Time/ %, 0 52).
 Aperture can be set to values 
between the minimum and maximum values for the lens.
 Use the exposure 
indicators to check exposure.

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.
AThe Exposure Indicator
If a shutter speed other than Bulb ( A) or Time ( %) is selected, the exposure indicator in 
the viewfinder shows 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 , 0 234), the amount of under- or over-e xposure is shown in increments of 1/3EV or 1/2EV (the illustrations below show the display in the viewfinder when  1/3 step is selected 
for Custom Setting b2).
 If the limits of the exposure metering  or live view exposure control 
system are exceeded, the indicator will flash.

the right and positive values on the left, see Custom Setting f8 ( Reverse indicators, 0 258).

❚❚Long Time-Exposures (M Mode Only)
Select the following shutter speeds for long time-
exposures of moving lights, the stars, night scenery, or 
fireworks.
• Bulb ( A ): The shutter remains open while the 
shutter-release button is held down.
 To prevent 
blur, use a tripod or an optional wireless remote 
controller ( 0309) or remote cord ( 0310).
• Time ( %): Start the exposure  by using the shutter-
release button on the camera or on an optional 
remote control, remote cord, or wireless remote 
controller.
 The shutter remains open for thirty 
minutes or until the button is pressed a second 
time.
1Ready the camera.
Mount the camera on a tripod or place it on a stable, level surface. To prevent 
light entering via the viewfinder interf ering with exposure, remove the rubber 
eyecup and cover the viewfinder with the supplied DK-5 eyepiece cap ( 060).
 
To prevent loss of power before the exposure is complete, use a fully charged 
EN-EL15 battery or an optional EH-5b AC adapter and EP-5B power connector.
 
Note that noise (bright spots, randomly-spaced bright pixels, or fog) may be 
present in long exposures; before shooting, choose  On for  Long exposure NR   
in the shooting menu ( 0228).
 If you will be using an ML-L3 remote control, 
select a remote control mode ( Delayed remote, Quick-response remote , or 
Remote mirror-up ) using the Remote control mode (ML-L3)  option in the 
shooting menu ( 0127).
