DIGITAL ZOOM
NOTES:
• To return to the original zoom position, press "INST. ZOOM" so that "I.ZOOM" disappears
from the viewfinder or LCD monitor.
• When the instant zoom is used, the more the image is magnified, the rougher the picture
becomes. Also even slight shaking of the camcorder is conspicuous.
