Using the Zoom
Rotate the zoom control to activate optical zoom.
Rotate in the direction of
g to zoom in on the subject.
Or rotate in the direction of
f to have a wider view.
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 magnification, rotating
the zoom control in the
g direction will trigger digital zoom. The subject can be
magnified up to 4× of the maximum optical zoom ratio.
When using digital zoom, the camera will focus on the center of the frame and the
focus area will not be displayed.

Digital Zoom and Interpolation
Unlike optical zoom, digital zoom uses a digital imaging process known as interpolation to magnify
images, resulting in slight deterioration of picture quality according to the image mode (
A 96) and
digital zoom magnification.
Interpolation is applied at zoom positions beyond V. When zoom is increased beyond the V
position, interpolation is initiated and the zoom indicator turns yellow to indicate that interpolation
is being applied.
The position of V moves to the right as image size decreases, allowing for confirmation of the
zoom positions at which shooting without interpolation is possible at the current image mode
setting.
• Digital zoom can be disabled from the Digital zoom option (A 127) in the setup menu
( A 116).
