Digital Zoom and Image Quality
When the camera is zoomed in to the maximum optical zoom magnification,
holding down g (i) triggers digital zoom. With digital zoom, you can magnify a
subject up to 4× the maximum magnification of optical zoom (3×) for a total of up
to 12× magnification.
Focus will be on the center of the screen (without active focus area display) when
digital zoom is in effect.
Unlike optical zoom, digital zoom uses a digital imaging process known as
interpolation to magnify images, resulting in slight deterioration of picture quality.
The V icon appears under the zoom indicator at the top of the monitor to mark
the maximum zoom ratio possible before deterioration from digital zoom occurs.
When the zoom ratio exceeds V towards the telephoto side, the zoom indicator
will turn yellow and picture quality will begin to deteriorate.
C Maximum zoom ratio without interpolation
The position of V under the zoom indicator moves closer to the telephoto side as the image size
selected for image mode (A 82) gets smaller. Deterioration from digital zoom will not occur until
the zoom ratio reaches the following levels for each mode.
When the zoom ratio reaches the following levels, zoom operations pause temporarily. If you
continue to press g (i) and increase the zoom after this point, the images will start to get grainier.
Digital zoom can be turned off (A108).
