Using the Zoom Function
Your camera has a combination of optical and
digital zoom functions that allow you to zoom in
on far away subjects or zoom out for a wide
angle shot.
The optical zoom is achieved by mechanically
adjusting the lens of the camera. The digital
zoom enlarges or shrinks the image using a
software process.
When the zoom lever is pressed, the zoom bar
appears on the LCD monitor.
Press [W] to zoom out for a wide-angle shot.
Press [T] to zoom in for a telephoto shot.
When the optical zoom factor is at maximum, zooming stops temporarily. Press the [T] again,
the camera switches to the digital zoom automatically and zooming continues.
Digital zoom works by enlarging the center portion of an image through a software
interpolation process. The digital zoom is used to achieve magnification levels up to approx.
4 times.
NOTE:
Digital zoom is unavailable when recording movies.
