SHOOTING A SNAPSHOT
Zoom Values for Each Image Size
The image deterioration point depends on the image size
(page 62). 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 “6M (2816 × 2112 pixels)” 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.
The digital zoom range of the zoom indicator is shown on the
monitor screen only while “Digital Zoom” is turned on.
