Digital Zoom

When the camera is already at the maximum optical zoom magnification, rotating the zoom control in the gdirection will trigger digital zoom. The subject can be magnified up to 4× of the maximum optical zoom ratio.

Focus will be on the center of the frame and the focus area will not be displayed when digital zoom is in effect.

Optical zoom (up to 24×).

Digital zoom is in effect.

CDigital Zoom and Interpolation

Unlike optical zoom, digital zoom uses a digital imaging process known as interpolation to magnify images, resulting in slight deterioration of picture quality according to the image size (A108) and digital zoom magnification.

Interpolation is applied at zoom positions beyond V. When zoom is increased beyond the V position, interpolation is initiated and the zoom indicator turns yellow to indicate that interpolation is being applied.

The position of Vmoves to the right as image size decreases, allowing for confirmation of the zoom positions at which shooting without interpolation is possible at the current image size setting.

When the image size is small

By using Digital zoom (A145) in the setup menu (A135), it is possible to restrict the magnification of the digital zoom within a range where images may not deteriorate, or to set the digital zoom so that it will not operate.
