The subject canbe magnified up to 4× of the maximum optical zoomratio.Focus will be on the center of the frame and the focus area will not be displayedwhen 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 (A90) anddigital zoom magnification.Interpolation is applied at zoom positions beyond V. When zoom is increased beyond the Vposition, interpolation is initiated and the zoom indicator turns yellow to indicate that interpolationis 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.• Digital zoom can be disabled from the Digital zoom option (A121) in the setup menu (A110).Zoom out Zoom inOpticalzoomDigitalzoomOptical zoom (up to 4×).
