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).
• 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 4× 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
(
A77) and digital zoom magnification.
Interpolation is applied at zoom positions beyond V. When the zoom is increased beyond the V
position, interpolation is initiated and the zoom indicator also turns yellow.
Additionally, V moves 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.
• Using Digital zoom in the setup menu ( A104), it is possible to restrict the magnification of the
digital zoom to a range where images do not deteriorate, or to set the digital zoom so that it does
not operate.
