Step 2 Frame a Picture
Digital ZoomWhen the camera is zoomed in to the maximum magnification (5×), holding down g(i) triggers digital zoom. The subject is magnified up to an additional 4×, for a total magnification of 20×.
When digital zoom is in effect, the focus area will not be displayed and the camera will focus on the subject in the center focus area.

If possible, digital zoom will create a picture by cropping the area visible in the monitor to the current image size (A77), 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.
Vis displayed, below the zoom indicator, at the maximum zoom ratio possible before interpolation is applied. When zoom is increased beyond this point, the zoom indicator turns yellow and interpolation is applied.
CMaximum zoom ratio without interpolation
As smaller image size settings (A77) are applied, Vshifts closer to the g(i) position. The degree 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. Interpolation will begin if you continue pressing g(i) to further increase the zoom ratio.

Digital zoom can be limited to the range at which interpolation is not in effect, or it can be turned off (A106).
