31Step 2 Frame a PictureBasic Photography and Playback: A (Auto) ModeUsing the ZoomRotate the zoom control to activate the optical zoom.Rotate the zoom control toward g to zoom in,increasing the size of the subject. Rotate the zoomcontrol toward f to zoom out, increasing the areavisible in the frame.• When the camera is turned on, the zoom is at themaximum wide-angle position.• Rotating the zoom control all the way in eitherdirection adjusts the zoom quickly, while rotating thecontrol partially adjusts the zoom slowly.• A zoom indicator is displayed at the top of themonitor when the zoom control is rotated.• The zoom can also be operated by rotating the side zoom control (A5) towardg or f.The function of the side zoom control can be set in the Assign side zoomcontrol (A198) in the setup menu (A185).Digital ZoomWhen the camera is zoomed in to the maximum optical zoom position, rotatingand holding the zoom control at g triggers digital zoom.Digital zoom can magnify the subject up to about 4× beyond the maximummagnification of the optical zoom.• The camera focuses at the center of the frame and the focus area is not displayedwhen digital zoom is in effect.C Digital Zoom and InterpolationUnlike the optical zoom, the digital zoom uses a digital imaging process known as interpolation tomagnify images, resulting in slight deterioration of picture quality depending on the image size(A84) and digital zoom magnification.Interpolation is applied at zoom positions beyond V when taking still images.When zoom is increased beyond the V position, interpolation is initiated and the zoom indicatorturns yellow to indicate that interpolation is being applied.The position of V moves to the right as image size decreases, allowing for confirmation of the zoompositions at which shooting without interpolation is possible at the current image mode setting.• Using Digital zoom (A197) in the setup menu (A185), it is possible to restrict the magnificationof the digital zoom to a range where images do not deteriorate, or to set the digital zoom so thatit does not operate.Optical zoom Digital zoomZoom out Zoom inMaximum optical zoom Digital zoom enabledWhen the image size is small
