During Recording
• While pictures are being recorded to the memory or memory card, the green (AF) lamp will blink,
and at the same time, a
(wait) icon will be displayed in the monitor or the memory icon (
or
) will blink. Do not turn the camera off, eject the memory card, or remove or dis-
connect the power source while pictures are being recorded. Cutting power or removing
the memory card in these circumstances could result in loss of data or in damage to the camera,
internal memory, or card.
Getting Good Results with Autofocus
Autofocus performs best when there is contrast between the subject and the back-
ground and the subject is evenly lit. It does not perform well if the subject is very dark
or moving rapidly, if there are objects of sharply differing brightness in the scene (e.g.,
the sun is behind your subject and their features are in deep shadow), or if there are
several objects at different distances from the camera at the center of the frame (e.g.,
your subject is inside a cage).
Sensitivity (ISO Equivalency)
Sensitivity is a measure of how sensitive the camera responds
to light. Your Nikon digital camera normally has a sensitivity
roughly equivalent to film with an ISO 80 rating. When lighting
is poor and Sensitivity (
87) is Auto, the camera will automat-
ically increase sensitivity, permitting faster exposures and mini-
mizing blur caused by inadvertent camera movement (camera
shake). An ISO icon will appear in the monitor to warn that the
picture may be slightly mottled.
AF-Assist Illuminator
COOLPIX4200 is equipped with an AF-assist illuminator. If lighting is poor, the built-in
AF-assist illuminator will light when the shutter-release button is pressed halfway, al-
lowing the camera to focus even when the subject is poorly lit.
The AF-assist illuminator will light in the following cases:
• AF area mode is set to
Auto or
Off in the shooting menu, or the focus area in the
center of the frame is selected when AF area mode is set to
Manual.
• Selecting the focus area in the center of the frame when shooting in
(portrait assist) mode
without using a framing guide (
• Shooting in
(night portrait assist) mode without using a framing guide (
33).
• Selecting the focus area in the center of the frame when shooting in
(close up) mode.
The AF-assist illuminator provides the following range:
• Zoom out: within approx. 2 m (6'6")
• Zoom in: within approx. 1.5 m (4'11")
Low Battery
If the flash fires when the low battery icon is displayed, the monitor will turn off while
the Speedlight recharges.
