• 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 "5M (2560 × 1920 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.
