Using the Zoom
Use the zoom buttons to activate optical zoom. Press
f (h) to zoom out, increasing the area visible in the
frame, or g (i) to zoom in so that the subject fills a
larger area of the frame.
When the camera is zoomed in to the maximum magnification (3×), holding down
g (i) triggers digital zoom. The subject is magnified up to 4×, for a total
magnification of 12×.
Focus will be on the center of the screen when digital zoom is in effect.
A monitor indicator shows the current zoom ratio.
B Digital Zoom and Image Quality
If possible, digital zoom will create a picture by cropping the area visible in the monitor to the
current image size (A82), increasing magnification without affecting quality.
If the crop would be smaller than the current image size, additional pixels are added through a
process known as interpolation, creating a slightly “grainy” image.
The amount of zoom available before interpolation is used depends on the option currently
selected for image size, as shown in the following table. The camera pauses temporarily in its
zooming operation when it reaches the maximum zoom ratio possible before interpolation is used.
V is displayed when interpolation is in effect.
