Camera Recording
Using the Zoom Feature
Zooming is a recording technique that lets you change the size of the subject in the scene.
For more professional-looking recordings, use the zoom function sparingly.
"T" side: for telephoto (subject appears closer)
"W" side; for wide-angle (subject appears farther away)
Zooming Speed (Dual speed zooming)
Press the power zoom button firmly for a high-speed zoom, press it softly for a relatively slow zoom.
When you shoot a subject using a telephoto zoom
If you cannot get a sharp focus while in extreme telephoto zoom, press the "W" side of the power
zoom button until the focus is sharp. You can shoot a subject that is at least about 3 1/4 feet (100 cm)
away from the lens surface in the telephoto position, or about 1/2 inches (1 cm) in the wide-angle
position.
Notes on Digital Zoom (CCD-TR83/TR93 only)
• More than 12x zoom is performed digitally, and the picture quality deteriorates as you go toward the
T side. If you do not want to use the digital zoom, set the D ZOOM function to OFF in the menu
system (p. 29).
■ The horizontal bar in the power zoom indicator separates the digital zooming zone (above the bar [a])
and the optical zooming zone (under the bar [b]). If you set the D ZOOM function to OFF, the part
above the bar disappears.
