Basic Operation Shutter Button The shutter button has two steps. You can press the shutter button halfway. Then you can further press the shutter button completely. Pressing halfway This activates autofocusing and the automatic exposure system that sets the shutter speed and aperture. The exposure setting (shutter speed and aperture) is displayed in the viewfinder and on the top LCD panel (9). Pressing completely This releases the shutter and takes the picture. Preventing Camera Shake Hand-held camera movement during the moment of exposure is called camera shake. It can cause blurred pictures. To prevent camera shake, note the following: • Hold and steady the camera as shown on the preceding page. • Press the shutter button halfway to autofocus, then slowly press the shutter button completely. Pressing the button will execute the same operation as pressing the shutter button halfway. If you press the shutter button completely without pressing it halfway first or if you press the shutter button halfway and then press it completely immediately, the camera will take a moment before it takes the picture. Even during menu display, image playback, or image recording, you can instantly go back to shooting-ready by pressing the shutter button halfway. 46
