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 d istance 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.

speed shutter mode when the subject is lit by
al-
ternating discharge-type light sources such as fluo-
rescent or mercury-vapor lights.
