SPECIAL TECHNIQUES
Zooming
When the focal length of the lens is varied by turning the zoom ring, the image appears to come nearer to or
retreat from the viewer.
Power zooming
Press "T" for zooming in and "W" for zooming out.
Zoom out
•Focusing may become unstable during the zooming-in operation. In this case , first zoom in in the Recording Standby mode
then, after pressing the FOCUS LOCK button to hold the focus fixed, zoom in or out in the Record mode .
•When shooting low-contrast subjects in the Zoom-in mode , the Videomovie automatically zooms out with the Focus lock mode
indicator blinking and focus being performed.
Focus lock
The GR-A30U's focus lock function is especially useful in the following situations:
•When things are passing between your subject and the VideoMovie, make sure to engage the focus lock function,
to lock your subject in focus before recording.
•If you want you r main subject to appear in a corner of the screen, you should first center it at the desired
distance,
then use the autofocus mode for focusing, engage the focus lock function, and turn the VideoMovie
till
the subject is where you want it.
•When the low-contrast warning blinks, it means that accurate focus cannot be achieved. Point the VideoMovie
at another subject, the same di stance from the camera as the one you want to record. Focus with the autofocus
function and engage the focus lock mode . Now turn back to your desired subject and record it.

mode is indicated on the viewfinder

Notes:
•The High-Speed Shutter mode requires slightly more
subject ilh.Jmination than the Standard Shutter
mode. Therefore, the low-light warning may blink
in the viewfinder. If so, switch to the Standard
Shutter mode.
•Picture color may be adversely affected in the high
speed shutter mode when the subject is lit by al-
ternating discharge-type light sources such as fluo-
rescent
or mercury-vapor lights.
