Snapshot Tutorial
• The image deterioration point
depends on the image size (page
24). 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 “7M”
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.
