ACalculating Angle of View (Continued)
The  DX (24 × 16)  angle of view is about 1.5 times smaller than the 
35 mm format angle of view, while the  1.2× (30 × 20) angle of view is 
about 1.2 times smaller and the  5 : 4 (30 × 24) angle of view is about 
1.1 times smaller.
 To calculate the focal length of lenses in 35 mm 
format when  DX (24 × 16) is selected, multiply the focal length of the 
lens by about 1.5, by about 1.2 when  1.2× (30 × 20) is selected, or by 
about 1.1 when  5 : 4 (30 × 24) is selected (for example, the effective 
focal length of a 50 mm lens in 35 mm format would be 75 mm when 
DX (24 × 16)  is selected, 60 mm when  1.2× (30 × 20) is selected, or 
55 mm when  5 : 4 (30 × 24) is selected).

The camera supports the Nikon Creative Lighting System (CLS) 
and can be used with CLS-compatible flash units.
 The built-in 
flash will not fire when an opt ional flash unit is attached.
The Nikon Creative Lighting System (CLS)
Nikon’s advanced Creative Lighting System (CLS) offers 
improved communication between the camera and compatible 
flash units for improved flash photography.
❚❚CLS-Compatible Flash Units
The camera can be used with the following CLS-compatible flash 
units:
•The SB-910, SB-900, SB-800, SB-700,  SB-600, SB-400, SB-300, and SB-R200 :

for white balance, the camera will automatically detect the filter and adjust white balance 
appropriately.
2 Wireless flash control is not available.

SB-800, or SB-700 flash unit or SU- 800 wireless Speedlight commander.

•SU-800 Wireless Speedlight Commander : When mounted on a CLS-
compatible camera, the SU-800  can be used as a commander 
for remote SB-910, SB-900, SB-800, SB-700, SB-600, or SB-R200 
flash units in up to three groups.
 The SU-800 itself is not 
equipped with a flash.
AGuide Number
To calculate the range of the flash  at full power, divide the Guide 
Number by the aperture.
 If, for example, the flash unit has a Guide 
Number of 34 m or 111 ft (ISO 100, 20 °C/68 °F); its range at an aperture 
of f/5.6 is 34 ÷ 5.6 or about 6.1 meters 
(or in feet, 111 ÷ 5.6 = approximately 19 ft 10 in.).
 For each twofold 
increase in ISO sensitivity, multip ly the Guide Number by the square 
root of two (approximately 1.4).
AThe Sync Terminal
A sync cable can be connected to the sync 
terminal as required.
 Do not connect 
another flash unit via a sync cable when 
performing rear-curtain sync flash 
photography with a flash unit mounted on 
the camera accessory shoe.

DNotes on Optional Flash Units
Refer to the flash unit manual for detailed instructions. If the unit 
supports CLS, refer to the section on CLS-compatible digital SLR 
cameras.
 The D810 is not included in the “digital SLR” category in the 
SB-80DX, SB-28DX, and SB-50DX manuals.
i-TTL flash control can be used at ISO sensitivities between 64 and 
12800.
 At high ISO sensitivities, noise (lines) may appear in photos 
taken with some optional flash unit s; if this occurs, choose a lower 
value.
 At values under 64 or over 128 00, the desired results may not be 
achieved at some ranges or aperture settings. If the flash-ready 
indicator flashes for about three seconds after a photograph is taken in 
i-TTL or non-TTL auto mode, the flash has fired at full power and the 
photograph may be underexposed (CLS-compatible flash units only; 
for information on the exposure and  flash charge indicators on other 
units, see the manual provided with the flash).
When an SC-series 17, 28, or 29 sync  cable is used for off-camera flash 
photography, correct exposure may not be achieved in i-TTL mode.
 We recommend that you select standard i-TTL flash control. Ta k e  a  t e s t  
shot and view the results in the monitor.
In i-TTL, use the flash panel or bounce adapter provided with the flash 
unit.
 Do not use other panels such as diffusion panels, as this may 
produce incorrect exposure.

The SB-910, SB-900, SB-800, SB-700, SB-600, and SB-400 provide red-
eye reduction, while the SB-910, SB-900, SB-800, SB-700, SB-600, and 
SU-800 provide AF-assist illumination with the following restrictions:
• SB-910 and SB-900 : AF-assist illumination is available when 
17–135 mm AF lenses are used with the focus points 
shown at right.
• SB-800, SB-600, and SU-800 : AF-assist 
illumination is available when 24–105 mm 
AF lenses are used with the focus points 
shown at right.
• SB-700 : AF-assist illumination is available when 24–
135 mm AF lenses are used with the focus points shown 
at right.
Depending on the lens used and scene recorded, the in-focus indicator 
( I ) may be displayed when the subject  is not in focus, or the camera 
may be unable to focus and the sh utter release will be disabled.
In exposure mode  e, the maximum aperture (minimum f-number) is 
limited according to ISO sensitivity, as shown below:
Maximum aperture at ISO equivalent of:
6410020040080016003200640012800
3.344.85.66.789.51113
If the maximum aperture of the lens  is smaller than given above, the 
maximum value for aperture will be the maximum aperture of the lens.
24–34 mm
35–49 mm
50–105 mm

Other Accessories
Power sources•
Rechargeable Li-ion Battery EN-EL15  (0 13, 14): Additional 
EN-EL15 batteries are available from local retailers and 
Nikon-authorized service representatives.
• Battery Charger MH-25a  (0 13): The MH-25a can be used 
to recharge EN-EL15 batteries.
 MH-25 battery chargers 
can also be used.
• Multi-Power Battery Pack MB-D12 : The MB-D12 is equipped 
with a shutter-release button,  B button, multi 
selector, and main- and sub-command dials for 
improved operation when taking photographs in 
portrait (tall) orientation.
 When attaching the MB-D12, 
remove the camera MB-D12 contact cover. A BL-5 
battery-chamber cover and an MH-26a or MH-26 
battery charger are required when using EN-EL18a and 
EN-EL18 batteries.
• Power Connector EP-5B, AC Adapter EH-5b : These accessories

see page 442 for details.
 Note that when the camera is 
used with an MB-D12, the EP-5B must be inserted into 
the MB-D12, not the camera.
 Do not attempt to use the 
camera with power connectors inserted into both the 
camera and MB-D12.
