Fantasea FP-4 Operator's manual - Zoom Control:
15
Zoom in for telephoto photos and larger subject size. Zoom out
for wide-angle scenes. It is generally not recommended to use
the zoom underwater as it is preferable to get physically closer
to your subject. The digital zoom has no value at all.
Zoom Control:
For capturing the tiny and exotic subjects that require close focus.
Macro focus is possible when the lens is in the wide-angle position.
Macro Focus:
Immediate review of most recent image is available that will
confirm that you captured the shot you want. However, if you
want to scroll through your images, or delete images from the
memory card, this should be done when you are topside and the
camera is out of the housing.
Quick Review:
Camera Standby Mode:
You can access the camera's menu to choose how long a period
of inactivity before the camera goes into standby mode. Options
are 30 seconds, one minute, five minutes, and 30 minutes. This
feature allows you to conserve battery power by placing the LCD
monitor on standby [sleep mode]. It is recommended that this
option is set for 30 seconds for the following reasons: to conserve
battery power and longer periods of time will cause a warming
of the LCD screen. This will cause heating of housing and this
can produce condensation and fogging of the lens port. If this
occurs and the condensation appears on the lens port then it will
have a negative impact on the quality of the images taken.
When you want to resume shooting, pressing any button will re-
activate the camera. However, if after the camera goes into standby,
a further period of three minutes goes by without any activity,
the camera will turn off [deep sleep mode]. You can turn it back
on by pressing and holding the triangular icon button--
Review/Restore [Playback] for about five seconds. The Welcome
to Nikon Coolpix screen will appear then it will display last image
taken. One additional press of the Review button will then return
the camera to active shooting mode.
