Chapter 2: Taking pictures and recording video clips 33
Using zoom
NOTE Zoom does not work while recording video clips.
Optical zoom
NOTE Frequent or extended use of optical zoom consumes a
lot of battery power and can drain your batteries quickly.
Optical zoom works like the zoom on a traditional film camera,
with physical lens elements moving inside the camera to make
the subject of your picture appear closer.
NOTE Press the Zoom Out
and Zoom In controls on
the Zoom lever to move the
lens between wide angle
and telephoto positions (1x
to 3x).
Digital zoom
Unlike optical zoom, digital zoom uses no moving lens parts.
The camera essentially crops the image, then uses interpolation
to enlarge the image to give the appearance of the subject in
the picture being from 1.25x to 4x closer.
1 Press the Live View button to turn on Live View .
2 Press the Zoom In control to optically zoom in to the
maximum level, then release the control.
