Zoom
Your camera is equipped with zoom
functions that enlarge the image using
optical zoom and two types of digital
processing. Digital zoom can be selected
from smart zoom or precision digital zoom.
When digital zoom is set, the zoom method
switches from optical zoom to digital zoom
when the zoom scale exceeds 3×.
To use only the optical zoom, set [Digital
Zoom] to [Off] on the Setup screen
(page 106). In this case, the digital zoom
area does not appear in the zoom scale
display bar on the LCD screen, and the
maximum zoom is 3×. The enlargement
method and the zoom scale differ according
to the image size and the zoom type, so
select the zoom to match the shooting
purpose.
When digital zoom is set and you press the
zoom button, the zoom scaling indicator
appears on the LCD screen as follows.

set smart zoom, set [Digital Zoom] to
[Smart] on the Setup screen (page 106).

the image size is set to [5M]. Smart
zoom cannot be used when the
image size is set to [5M] or [3:2], so
set a different image size.
• When using the smart zoom, the image on the
LCD screen may look rough. However, this has
no effect on the recorded image.
• You cannot use the smart zoom in the Multi
Burst mode.
Precision digital zoom

All image sizes are enlarged up to a
maximum 6×. This function cuts out and
enlarges a certain portion of the image, so
the image quality deteriorates. To set

(page 106).
