Point-and-Shoot Photography and Movie Recording
❚❚
Recording Movies
The display shows the approximate amount of
recording
time
available; but note that the actual length that can be
recorded varies with the scene recorded and subject
movement. Recording may end before the time indicated to
prevent overheating. The maximum length for individual clips
is 29 minutes or 4 GB.
The camera may record sounds made by camera controls or
by the lens during focusing or when aperture is adjusted to
reflect changes in the brightness of the subject. Digital zoom
can be used, but footage shot with digital zoom will be
noticeably “grainy” (
13); optical zoom is not available.
Distortion may be visible in the monitor and the final movie if
the camera is panned horizontally or an object moves at high
speed through frame. Bright light sources may leave after-
images when the camera is panned while flicker and banding
may be visible under fluorescent, mercury vapor, or sodium
lamps. Depending on the zoom ratio and distance to the
subject, “moiré” may also be visible where the scene features
regular repeating patterns; this is a naturally-occurring
interference pattern arising from the interaction of the image
sensor grid with a regular repeating grid pattern in the subject
and does not indicate a malfunction.
The temperature of the camera
may rise if it is used for
extended periods or in hot environments. If there is risk of
overheating during movie recording, a count-down timer will
be displayed; recording will end automatically and the camera
will turn off when the timer expires. Wait for the camera to
cool.

Single AF
(the default setting;

Keeping the button pressed halfway, recompose the shot
with your original subject in the desired position.
