Step 3 Frame a Picture
Basic Steps for Shooting and Playback
Using the Zoom
Use the zoom control to activate optical zoom.
• Rotate the zoom control to g to zoom in so that the
subject fills a larger area of the frame.
• Rotate the zoom control to f to zoom out, thus
increasing the area visible in the frame.
• The zoom position is set at the maximum wide-angle
position when the camera is turned on.
• A zoom indicator is displayed at the top of the
monitor when the zoom control is rotated.
Digital Zoom
When the camera is zoomed in to the maximum optical zoom position, rotating
and holding the zoom control at g triggers digital zoom. The subject is magnified
up to 4× the maximum optical zoom ratio.
• The camera focuses at the center of the frame and the focus area is not
displayed when digital zoom is in effect.
C Digital Zoom and Interpolation
Unlike optical zoom, digital zoom uses a digital imaging process known as interpolation to magnify
images, resulting in slight deterioration of image quality according to the image mode (A57) 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 indicator turns yellow to
indicate that interpolation is being applied. V moves to the right as the image size becomes
smaller, allowing you to confirm the zoom position that can be used to capture still images without
image degradation before shooting at the current image size setting.
• Digital zoom can be disabled from the Digital zoom option (A83) in the setup menu (A82).
