Basic Photography and Playback: Easy Auto Mode Step 3 Focus and Shoot B Autofocus Autofocus may not perform as expected in the following situations. In some rare cases, the subject may not be in focus despite the fact that the active focus area and the focus indicator glow green: • Subject is very dark • Objects of sharply differing brightness are included in the scene (e.g. the sun is behind the subject and is in deep shadow) • No contrast between the subject and surroundings (e.g. when the subject is standing in front of a white wall, wearing a white shirt) • Several objects are at different distances from the camera (e.g. the subject is inside a cage) • Subject is moving rapidly In the situations noted above, try pressing the shutter-release button halfway to refocus several times, or focus on another subject and use focus lock. When using focus lock, be sure that the distance between the camera and the subject with which focus was locked is the same as that for the actual subject. D Focus Lock To focus on off-center subject, use focus lock as described blow. • Be sure that the distance between the camera and the subject does not change while focus is locked. 10 Position the subject in the center of the frame. Press the shutterrelease button halfway. 10 Confirm that the focus indicator (Q) is green. 10 Continue holding down the shutterrelease button halfway and recompose the picture. Press the shutterrelease button the rest of the way down. D AF-assist Illuminator and Flash If the subject is poorly lit, the AF-assist illuminator may light by pressing the shutter-release button halfway, or the flash may fire by pressing the shutter-release button all the way down. The illuminator has a range of about 2.4 m (7 ft. 10.5 in.) at the maximum wide-angle position and 1.7 m (5 ft. 6.9 in.) at the maximum telescopic position. The AF-assist illuminator can be set to [Off] manually (A 87), although in this case the camera may not focus when lighting is poor. 23
