Restrictions
• 
Smart Photo Selector mode is not supported.
• Motion Snapshots can be recorded only when an AF-S lens is
attached and AF-S (Single AF) is selected for focus mode and
then only when the camera is in focus. Do not attempt to
adjust focus using the focus ring; if the ring is rotated, an error
message will be displayed and pictures can not be taken until
the message has cleared from the display and the camera has
been refocused by pressing the shutter-release button halfway.
• Shutter speeds of 1 s or slower are not available.
• The sound monitor switch and focus operation button (Focus
Lock/MEMORY RECALL/AF Start) have no effect.
Precautions for Use
• 
Lenses over 380 g (13.4 oz) should be supported at all times. Do
not hold the camera or carry the camera by the strap without
supporting the lens. Failure to observe this precaution could
damage the camera lens mount.
• Lines may appear in photographs taken with non-CPU lenses
stopped down to minimum aperture.
• The camera continues to adjust exposure during movie record-
ing. Select exposure mode A or M to prevent sounds made by
the lens being picked up by the microphone.
• Autofocus may be less precise when S Shutter-priority auto,
A
Aperture-priority auto, or M Manual is selected for Expo-
sure mode.
• During continuous shooting, focus is fixed at the position for
the first shot in each burst and frame rates will slow in modes
other than Electronic (Hi).
• The display may change during shooting when Electronic (Hi)
is selected, but this has no effect on photographs.
• Certain lenses will block the AF-assist illuminator and, at some
distances, the flash.
• The tops and bottoms may be missing from circular bokeh
shapes created at wide apertures using lenses with a maximum
aperture of f/1.4.
