Using Two Memory Cards
When two memory cards are inserted in the camera, you can use the Role played by 
card in Slot 2  item in the shooting menu to choose the role played by the card in Slot 
2.
 Choose from  Overflow (the card in Slot 2 is used only when the card in Slot 1 is 
full),  Backup  (each picture is recorded twice, once to the card in Slot 1 and again to 
the card in Slot 2), and  RAW Slot 1—JPEG Slot 2  (as for Backup , except that the NEF/
RAW copies of photos recorded at settings of NEF/RAW + JPEG are recorded only to 
the card in Slot 1 and the JPEG copies only to the card in Slot 2).
A“Backup” and “RAW Slot 1—JPEG Slot 2”
The camera shows the number of exposures remaining on the card with the least amount of 
memory.
 Shutter release will be disabled when either card is full.
ARecording Movies
When two memory cards are inserted in the camera, the slot used to record movies can be 
selected using the  Movie settings> Destination  option in the shooting menu ( 065).

Focus
This section describes the focus options available when photographs are framed in 
the viewfinder.
 Focus can be adjusted automatica lly (see below) or manually 
( 0 103).
 The user can also select the focus  point for automatic or manual focus 
( 0 101) or use focus lock to focus to recompose photographs after focusing ( 0102).
To use autofocus, rotate the focus-mode selector to  AF.
Autofocus Mode
Choose from the following autofocus modes:
Autofocus
ModeDescription 
AF-A Auto-servo AF
: Camera automatically selects single-ser vo autofocus if subject is stationary, 
continuous-servo autofocus if subject is moving.
AF-S Single-servo AF
: For stationary subjects. Focus locks when shutter-release button is pressed 
halfway.
 At default settings, shutter can only be released when in-focus indicator is 
displayed ( focus priority ; 0 221).
AF-C Continuous-servo AF
: For moving subjects. Camera focuses continuously while shutter-
release button is pressed halfway; if subject moves, camera will engage  predictive focus 
tracking  (0 100) to predict final distance to su bject and adjust focus as necessary.
 At 
default settings, shutter can be released whether or not subject is in focus ( release 
priority ; 0 221).
APredictive Focus Tracking
In  AF-C  mode or when continuous-servo autofocus is selected in  AF-A mode, the camera will 
initiate predictive focus tracking if the subject moves toward or away from the camera while 
the shutter-release button is pressed halfway.
 This allows the camera to track focus while 
attempting to predict where the subject will be when the shutter is released.

AGetting Good Results with Autofocus
Autofocus does not perform well under the conditions listed below.
 The shutter release may 
be disabled if the camera is unable to focus  under these conditions, or the in-focus indicator 
( I ) may be displayed and the camera may sound a beep, allowing the shutter to be released 
even when the subject is not in focus.
 In these cases, focus manually ( 0103) or use focus 
lock ( 0102) to focus on another subject at the same distance and then recompose the 
photograph.
There is little or no contrast 
between the subject and the 
background .
Example : Subject is the same 
color as the background.  The focus point contains 
areas of sharply contrasting 
brightness
.
Example : Subject is half in 
the shade. 
The focus point contains 
objects at different distances 
from the camera .
Example : Subject is inside a 
cage.  Background objects appear 
larger than the subject.
Example
: A building is in the 
frame behind the subject.
The subject is dominated by 
regular geometric patterns .
Example : Blinds or a row of 
windows in a skyscraper. The subject contains many 
fine details
.
Example : A field of flowers or 
other subjects that are 
small or lack variation in 
brightness.

AF-Area Mode
Choose how the focus point for autofocus is selected.
•Single-point AF : Select the focus point as descri bed on page 101; the camera will 
focus on the subject in the selected focus point only.
 Use with stationary subjects.
• Dynamic-area AF : Select the focus point as  described on page 101.
 In AF-A  and  AF-C 
focus modes, the camera will focus base d on information from surrounding focus 
points if the subject briefly leaves the selected point.
 The number of focus points 
varies with the mode selected:
- 9-point dynamic-area AF : Choose when there is time  to compose the photograph or 
when photographing subjects that are mo ving predictably (e.g., runners or race 
cars on a track).
- 21-point dynamic-area AF : Choose when photographin g subjects that are moving 
unpredictably (e.g., players at a football game).
- 39-point dynamic-area AF : Choose when photographin g subjects that are moving 
quickly and can not be easily framed  in the viewfinder (e.g., birds).
• 3D-tracking : Select the focus point as  described on page 101.
 In AF-A  and  AF-C focus 
modes, the camera will track subjects that  leave the selected focus point and select 
new focus points as required.
 Use to quickly compose pictures with subjects that 
are moving erratically from side to  side (e.g., tennis players).
 If the subject leaves 
viewfinder, remove your finger from th e shutter-release button and recompose 
the photograph with the subject in the selected focus point.
• Auto-area AF : The camera automatically detects the subject and 
selects the focus point.
 I f a t ype G, E, or D lens is used ( 0287), 
the camera can distinguish human subjects from the 
background for improved subject detection.
 The active focus 
points are highlighted briefly after the camera focuses; in  AF-C 
mode or when continuous-servo autofocus is selected in  AF-A 
mode, the main focus point re mains highlighted after the 
other focus points have turned off.

AF-area mode can be selected by pressing 
the AF-mode button and rotating the sub-
command dial until the desired setting is 
displayed in the viewfinder or control panel.
A3D-tracking
When the shutter-release button is pressed half way, the colors in the area surrounding the 
focus point are stored in the camera.
 Consequently 3D-tracking may not produce the 
desired results with subjects that are the same  color as the background or that occupy a very 
small area of the frame.

Focus Lock
Focus lock can be used to change the composition after focusing, making it possible 
to focus on a subject that will not be in  a focus point in the final composition.
 If the 
camera is unable to focus using autofocus ( 098), focus lock can also be used to 
recompose the photograph after focusing on another object at the same distance as 
your original subject.
 Focus lock is most effective when an option other than auto-
area AF is selected for AF-area mode ( 099).
1Focus.
Position the subject in the selected focus point 
and press the shutter-release button halfway to 
initiate focus.
 Check that the in-focus indicator 
( I ) appears in the viewfinder.
2Lock focus.
AF-A and AF-C focus modes : With the shutter-release 
button pressed halfway ( q), press the  AAE-L/AF-L  
button ( w) to lock both focus and exposure (an 
AE-L  icon will be displayed in the viewfinder).
 
Focus will remain locked while the  AAE-L/AF-L  
button is pressed, even if you later remove your 
finger from the shutter-release button.
AF-S focus mode : Focus locks automatically when 
the in-focus indicator appears, and remain 
locked until you remove your finger from the 
shutter-release button.
 Focus can also be locked 
by pressing the  AAE-L/AF-L  button (see above).
3Recompose the photograph and shoot.
Focus will remain locked between shots if you 
keep the shutter-release button pressed halfway 
(AF-S ) or keep the  AAE-L/AF-L  button pressed, 
allowing several photogra phs in succession to 
be taken at the same focus setting. 
Do not change the distance between the camera and the subject while focus lock is 
in effect.
 If the subject moves, focus again at the new distance.

Manual Focus
Manual focus is available for lenses that do not support autofocus (non-AF NIKKOR 
lenses) or when the autofocus does not produce the desired results ( 098).
• AF-S lenses : Set the lens focus mode switch to  M.
• AF lenses : Set the lens focus mode switch (if present) 
and camera focus-mode selector to  M.
• Manual focus lenses : Set the camera focus-mode selector to  M.
To focus manually, adjust the lens focus ring until the 
image displayed on the clear matte field in the 
viewfinder is in focus.
 Photographs can be taken at 
any time, even when the image is not in focus.
❚❚ The Electronic Rangefinder
If the lens has a maximum aperture of f/5.6 or faster, 
the viewfinder focus indicator can be used to confirm 
whether the subject in the selected focus point is in 
focus (the focus point can be  selected from any of the 
39 focus points).
 After positioning the subject in the 
selected focus point, press  the shutter-release button 
halfway and rotate the lens focus ring until the in-focus indicator ( I) is displayed.
 
Note that with the subjects listed on pa ge 98, the in-focus indicator may sometimes 
be displayed when the subject is not in fo cus; confirm focus in the viewfinder before 
shooting.
DAF Lenses
Do not use AF lenses with the lens focus mode switch 
set to  M and the camera focus-mode selector set to  AF.
 
Failure to observe this precaution could damage the 
camera or lens.
AFocal Plane Position
To determine the distance between your subject and the 
camera, measure from the focal plane mark ( E) on the 
camera body.
 The distance between the lens mounting 
flange and the focal plan e is 46.5 mm (1.83 in.).
