Problems and solutions

• Wait for recording and other operations to end.
• If the problem persists, turn the camera off.
• If the camera does not turn off, remove and reinsert the battery.
• If you are using an AC adapter, disconnect and reconnect the AC adapter.
  • Any data currently being recorded will be lost.
  • Data that have already been recorded are not affected by removing or disconnecting the power source.

• Have you changed the monitor mode? Choose a different monitor mode using the M button.
• Have you limited the choice of monitor modes available using the [Limit monitor mode selection] item in the setup menu? Adjust settings as required.
• Dust, lint, or other foreign matter on the eye sensor may prevent it functioning normally. Clean the eye sensor with a blower.

Was the DISP button pressed? If the DISP button is pressed during playback or shooting, the display of the viewfinder or monitor changes (Photo information, d19: Custom monitor shooting display, d20: Custom viewfinder shooting display).

• Rotate the diopter adjustment control to adjust viewfinder focus.
• If adjusting viewfinder focus does not correct the problem, set the focus mode to AF-S and the AF-area mode to single-point AF. Next, select the center focus point, choose a high-contrast subject, and focus using autofocus. With the camera in focus, use the diopter adjustment control to bring the subject into clear focus in the viewfinder.

Choose longer delays for Custom Setting c3 [Power off delay].

The display refresh rate may drop about 20 seconds before the standby timer turns off. The length of time before the standby timer expires automatically can be selected using Custom Setting c3 [Power off delay] > [Standby timer].

More time will be needed to find files if the memory card contains large numbers of files or folders.

• Is a memory card inserted, and if so, does it have space available?
• If you selected mode S after selecting a shutter speed of “Bulb” or “Time” in mode M, choose a different shutter speed.
• Is [Release locked] selected for [Slot empty release lock] in the setup menu?

Select [Off] for Custom Setting d5 [Exposure delay mode].

• Burst shooting cannot be used in conjunction with HDR.
• If the built-in flash is used with [Continuous L], [Continuous H], or [Continuous H (extended)] selected for release mode, only one picture will be taken each time the shutter-release button is pressed. If high-speed frame capture + is selected for release mode, the flash is disabled and burst photography is enabled.

• Is the camera in manual focus mode? To enable autofocus, select AF-A, AF-S, AF-C, or AF-F for focus mode.
• The camera may be unable to focus if:
  • the subject contains lines parallel to the long edge of the frame,
  • the subject lacks contrast,
  • the subject in the focus point contains areas of sharply contrasting brightness,
  • the focus point includes night-time spot lighting or a neon sign or other light source that changes in brightness,
  • flicker or banding appears under fluorescent, mercury-vapor, sodium-vapor, or similar lighting,
  • a cross (star) filter or other special filter is used,
  • the subject appears smaller than the focus point, or
  • the subject is dominated by regular geometric patterns (e.g., blinds or a row of windows in a skyscraper).
• In focus mode AF-C, the focus point may flash while the shutter-release button is pressed halfway, indicating that the camera is no longer able to focus. The focus operation can be resumed by releasing and then pressing the button again.

• If AF-C is selected for focus mode or if AF-A is selected and you are shooting in AF-C, a beep will not sound when the camera focuses.
• The beep does not sound if [ON] is selected for [Silent mode] in the setup menu.
• A beep will sound if an option other than [Off] is selected for [Camera sounds] > [Beep on/off] in the setup menu.
• The beep does not sound in video mode.

Using a flash restricts the range of shutter speeds available. Flash sync speed can be set to values of 1/200–1/60 s using Custom Setting e1 [Flash sync speed]. When using optional flash units that support auto FP high-speed sync, choose [1/250 s (Auto FP)] or [1/200 s (Auto FP)] for shutter speeds as fast as 1/4000 s (or 1/2000 s if [Electronic front-curtain shutter] is selected for Custom Setting d6 [Shutter type]).

If AF-C is selected for focus mode or if AF-A is selected and you are shooting in AF-C, press the A (g) button to lock the focus.

Focus-point selection is not available when [Auto-area AF] is selected for AF-area mode.

Is [ON] selected for [Long exposure NR] in the photo shooting menu?

• The effects of changes to settings that affect exposure and color are not visible in the display when [Adjust for ease of viewing] is selected for Custom Setting d10 [View mode (photo Lv)]. If Custom Setting d10 is set to [Show effects of settings] > [Only when flash is not used], display brightness is adjusted for ease of viewing (as per [Adjust for ease of viewing]) even when using the built-in flash or when a flash unit is attached and ready to fire.
• Note that changes to [Monitor brightness] and [Viewfinder brightness] have no effect on images recorded with the camera.

Select [Video flicker reduction] in the video recording menu and choose an option that matches the frequency of the local AC power supply.

Bright regions or bands may occur if the subject is lit by a flashing sign, flash, or other light source with brief duration.

• Are there smudges on the front or rear (mount-side) lens elements?
• Is there foreign matter on the image sensor? See “Manual cleaning” (Manual cleaning), or consult a Nikon-authorized service representative.

You may notice ghosting or flare in shots that include the sun or other bright light sources. These effects can be mitigated by attaching a lens hood or by composing shots with bright light sources well out of the frame. You can also try such techniques as removing lens filters or choosing a different shutter speed.

With fast shutter speeds and/or fast lenses, you may notice irregularities in how Bokeh is shaped. The effect can be mitigated by choosing slower shutter speeds and/or higher f-numbers.

• Shooting may end automatically to prevent the camera overheating, for example if:
  • the ambient temperature is high,
  • the camera has been used for extended periods to record videos, or
  • the camera has been used in continuous release modes for extended periods.
• If photographs cannot be taken because the camera is running hot, turn the camera off and wait for it to cool before trying to take photographs again. Note that the camera may feel warm to the touch, but this does not indicate a malfunction.

• To reduce noise, adjust settings such as ISO sensitivity, shutter speed, or Active D-Lighting.
• At high ISO sensitivities, noise may become more noticeable in long exposures or in pictures recorded when the camera temperature is elevated.
• Randomly-spaced bright pixels, fog, or bright spots may arise as a result of increases in the temperature of the camera’s internal circuits. Turn the camera off when it is not in use.
• Randomly-spaced bright pixels, fog, lines or unexpected colors may appear if you press the X button to zoom in on the view through the lens during shooting.
• Note that the distribution of noise in the display may differ from that in the final picture.
• This issue can sometimes be addressed by checking and optimizing the image sensor. Perform pixel mapping using [Pixel mapping] in the setup menu.

The subject is too dark or too bright.

Pictures created with cameras of other types cannot serve as sources for preset manual white balance.

• White balance bracketing is not available when an NEF (RAW) or RAW + JPEG/HEIF option is selected for image quality.
• White balance bracketing cannot be used in multiple exposure and HDR overlay modes.

[Auto] is selected for [Set Picture Control] or as the basis for a Custom Picture Control created using [Manage Picture Control], or [A] (auto) is selected for [Quick sharp], [Contrast], or [Saturation]. For consistent results over a series of photographs, choose a setting other than [A] (auto).

The option selected for metering cannot be changed during exposure lock.

Changes to exposure compensation in mode M apply only to the exposure indicator and have no effect on shutter speed or aperture.

Uneven shading may appear in long exposures shot at shutter speeds of “Bulb” or “Time”. The effect can be mitigated by selecting [ON] for [Long exposure NR] in the photo shooting menu.

• Is [OFF] selected for Custom Setting a11 [Built-in AF-assist illuminator]?
• The illuminator does not light in video mode.
• If AF-C is selected for focus mode, if AF-A is selected and you are shooting in AF-C, or if MF is selected, the illuminator does not light.

• Is [Microphone off] selected for [Microphone sensitivity] in the video recording menu?
• Was the video recorded with [Manual] chosen for [Microphone sensitivity] in the video recording menu and a low sensitivity selected?
