MAGNIFICATION BUTTON AND ELECTRONIC MAGNIFICATION

The magnification button can be used to activate the digital zoom (p. 46) or enlarge the center of the image by 4X to aid manual focusing. The function of the magnification button is selected in the advanced 1 section of the recording-mode menu (p. 80).

When electronic magnification is selected on the menu, the digital zoom is canceled. Electronic mag- nification can only be used during manual focus. The magnified display cannot be used to set the exposure.

Press the magnification button on the back of the camera. The magnifi- er icon is displayed on the monitors when electronic magnification is in effect.

Pressing the magnification button a second time cancels the function. When the shutter-release button is pressed partway down, the magni- fied display is canceled showing the entire image area.
