Using the Zoom
Rotate the zoom control to activate the optical zoom.
• To zoom in so that the subject fills a larger area of
the frame, rotate toward
g (telephoto zoom
position).
• To zoom out so that the area visible increases in the
frame, rotate toward f (wide-angle position).
• Rotating the zoom control all the way in either
direction adjusts the zoom quickly, while rotating
the control partially adjusts the zoom slowly (except
during movie recording).
• A zoom indicator is displayed at the top of the
monitor when the zoom control is rotated.
Digital Zoom
When the camera is already at the maximum optical zoom position, rotating the
zoom control toward
g (telephoto zoom position) triggers the digital zoom.
Digital zoom can magnify the subject up to about 2× beyond the maximum
magnification of the optical zoom.
• The focus will be at the center of the frame and the focus area will not be
displayed when the digital zoom is in effect.

Digital Zoom and Interpolation
Unlike the optical zoom, the digital zoom uses a digital imaging process known as interpolation to
magnify images, resulting in slight deterioration of image quality depending on the image size
(
A73) and digital zoom magnification.
V indicates the zoom position where interpolation is applied when shooting still pictures. When the
zoom is increased beyond the V position, interpolation is initiated and the zoom indicator also turns
yellow.
V moves to the right as the image size becomes smaller, allowing you to confirm the zoom position
that can be used to capture still images without image degradation before shooting at the current
image size setting.
• Digital zoom can be disabled from the Digital zoom option in the setup menu ( A98).
