Basic Photography and Playback: Auto Mode Step 2 Frame a Picture Digital Zoom and Image Quality When the camera is zoomed in to the maximum optical zoom magnification, rotating and holding the zoom control at g (i) triggers digital zoom. With digital zoom, you can magnify a subject up to 4× the maximum magnification of optical zoom (18×) for a total of up to 72× magnification. Focus will be on the center of the screen (without active focus area display) when digital zoom is in effect. Optical zoom (up to 18×). 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 (A 89) 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 hold the zoom control at g (i) and increase the zoom after this point, the images will start to get grainier.
