SHOOTING A SNAPSHOT
■
Optical Zoom and Digital Zoom Switch Point
If you hold down the [ ] side of the zoom button in step 2 of
the above procedure, the zoom operation will stop when the
optical zoom factor reaches its maximum. Momentarily releasing
the zoom button and then holding down its [ ] side will switch
to digital zoom, which you can use to set an even higher zoom
factor.
• When the zoom pointer moves past the maximum limit of
optical zoom. Also, the zoom bar indicates the approximate
zoom factor.
• The image deterioration point depends on the image size
(page 68). 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.
