Using the Zoom
Rotate the zoom control to activate the optical zoom.
Rotate in the
g direction to zoom in so that the
subject fills a larger area of the frame. Rotate in the f
direction to zoom out so that the area visible increases
in the frame.
• 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 (telephoto) direction triggers the digital zoom. The
subject can be magnified up to 4× the maximum optical zoom ratio.
The focus will be on the center of the frame and the focus area will not be displayed
when the digital zoom is in effect.
C
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 picture quality depending on the image size
(
A70) 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 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 still pictures without interpolation is possible at the current image size
setting.
• Using Digital zoom ( A178) in the setup menu (A167), 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.
