Image Quality and Size
Together, image quality and size determine how much space each photograph 
occupies on the memory card.
 Larger, higher quality images can be printed at larger 
sizes but also require more memory, meanin g that fewer such images can be stored 
on the memory card ( 0348).
Image Quality
Choose a file format and compression ratio (image quality).
Image quality can be set by pressing the  X (T ) button and rotating the main 
command dial until the desired setting  is displayed in the control panel.

OptionDescription
O Size priority
Images are compressed to produce relatively uniform file size.
P Optimal quality Optimal image quality.
 File size varies with scene recorded.
OptionDescription
N Lossless 
compressed NEF images are compressed using a reversible algorithm, reducing 
file size by about 20–40% with no effect on image quality.
O Compressed NEF images are compressed using a non-reversible algorithm, 
reducing file size by about 35–55% with almost no effect on image 
quality.
OptionDescription
q 12-bit NEF (RAW ) images are recorded at a bit-depth of 12 bits.
r 14-bit NEF (RAW ) images are recorded at a bit depth of 14 bits, producing 
files larger than those with a bit depth of 12 bits but increasing the 
color data recorded.
ANEF (RAW) Images
NEF (RAW ) images can be viewed on the camera or using software such as Capture NX 2 
(available separately;  0309) or ViewNX 2 (available on the supplied ViewNX 2 CD).
 Note 
that the option selected for image size does not affect the size of NEF (RAW ) images; when 
viewed on a computer, NEF (RAW ) images have the dimensions given for large ( #-size) 
images in the table on page 68.
 JPEG copies of NEF (RAW ) images can be created using the 
NEF (RAW) processing  option in the retouch menu ( 0282).
ANEF+JPEG 
When photographs taken at settings of NEF (R AW ) + JPEG are viewed on the camera with 
only one memory card inserted, only the JPEG image will be displayed.
 If both copies are 
recorded to the same memory card, both copies will be erased when the photo is deleted.
 If 
the JPEG copy is recorded to a separate memory card using the  Role played by card in 
Slot 2 > RAW Slot 1—JPEG Slot 2  option, deleting the JPEG copy will not delete the NEF 
(RAW ) image.

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 ( 0169).

Focus
This section describes the focus options available when photographs are framed in 
the viewfinder.
 Focus can be adjusted automatically (see below) or manually ( 078). 
The user can also select the focus po int for automatic or manual focus (075) or use 
focus lock to focus to recompose photographs after focusing ( 076).
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 ( I) is 
displayed ( focus priority ; 0 231).
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  to predict final distance to subject and adjust focus as necessary.
 At default 
settings, shutter can be released whether or not subject is in focus ( release priority; 
0 231).
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.

Autofocus mode can be selected by pressing the AF-
mode button and rotating the main command dial 
until the desired setting is displayed in the viewfinder 
or control panel.

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 ( 078) or use focus lock 
( 0 76) 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.
