The subject is magnifiedup to 4× the maximum optical zoom ratio.Focus will be on the center of the screen (without active focus area display) whendigital 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.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 forconfirmation of the zoom positions at which shooting without interpolation is possible at thecurrent image mode setting.Digital zoom can be disabled from the Digital zoom option (A 135) in the setup menu (A 127).Zoom out Zoom inOpticalzoomDigitalzoomMaximumoptical zoomDigital zoom isin effect.When an image size is small
