25Step 2 Frame a PictureBasic Photography and Playback: A (Auto) ModeUsing the ZoomUse the zoom control to activate optical zoom. Rotatethe zoom control to g to zoom in so that the subject fillsa larger area of the frame, or f to zoom out, thusincreasing the area visible in the frame.A zoom indicator is displayed at the top of the monitorwhen the zoom control is rotated.Digital ZoomWhen the camera is zoomed in to the maximum optical zoom position, rotatingand holding the zoom control at g triggers digital zoom. The subject is magnifiedup to 2× the maximum optical zoom ratio. The camera focuses at the center of theframe and the focus area is not displayed when digital zoom is in effect.C Digital Zoom and InterpolationUnlike optical zoom, digital zoom uses a digital imaging process known as interpolation to magnifyimages, resulting in slight deterioration of picture quality according to the image mode (A 37) anddigital zoom magnification.Interpolation is applied at zoom positions beyond V when taking still pictures. When zoom isincreased beyond the V position, interpolation is initiated and the zoom indicator turns yellow toindicate that interpolation is being applied. The position of V moves to the right as image sizedecreases, allowing for confirmation of the zoom positions at which shooting without interpolationis possible at the current image mode setting.Digital zoom can be disabled from the Digital zoom option (A 131) in the setup menu (A 120).Zoom out Zoom inOpticalzoomDigitalzoomMaximum optical zoom Digital zoom enabledSmall image size
