If you hold the zoom controller towards (Telephoto), the zoom operation will stop
when the optical zoom factor reaches its maximum. Momentarily releasing the zoom
controller and then holding it again towards
(Telephoto) will switch to digital zoom,
which you can use to set an even higher zoom factor.
• During zoom, a zoom bar on the monitor screen shows the current zoom setting.
• The image deterioration point
depends on the image size (page
32). The smaller the image size,
the higher the zoom factor you
can use before reaching the
image deterioration point.
• Though digital zoom generally
causes a deterioration of image
quality, some digital zoom
without image deterioration is
possible with image sizes of
“10M” and smaller. The range in
which you can use digital zoom
without image deterioration is
indicated on the display. The
deterioration point depends on
the image size.
