2 ■Zoom position (Flash coverage angle) setting Next, set the zoom (flash coverage angle) to match the focal length of the lens you are using. ■Auto Zoom (A.Zoom) If both the camera and lens are autofocus, you can automatically set the flash coverage angle according to the focal length of the lens by pressing the shutter release button of the camera halfway down. The auto zoom function operates while the exposure metering timer is operating (while information is being displayed in the viewfinder). If you are setting the format manually, return the setting switch to the upper (white dot) position. When (M.Zoom) is displayed on the LCD panel, press the zoom button (ZOOM) repeatedly until (A.Zoom) is displayed. ● When the flash mode is set to auto flash, the auto zoom function does not operate even if the camera and lens are both autofocus. Set the zoom manually to match the lens angle of view. ■Manual Zoom (M.Zoom) If one or both of the camera and lens are manual focus, you must set the flash coverage angle manually. If you are setting the format manually, return the setting switch to the upper (white dot) position. Press the zoom button (ZOOM) until the focal length of the lens being used is displayed on the LCD panel or if it can not be displayed exactly one wider than the lens focal length. The zoom position is switched in the order shown in the diagram on page 23. 21
