Shooting Range and Focusing • Focusing may not be possible in some shooting conditions. • In low-light conditions, Servo AF may not be activated (AF frames may not turn blue) when you press the shutter button halfway. In this case, the focus and exposure are set according to the specified AF frame mode. • If adequate exposure cannot be obtained, shutter speeds and aperture values are displayed in orange. Release the shutter button, and then press it halfway again. • AF lock shooting is not available. • [AF-Point Zoom] on the 4 tab is not available. • Not available when using the self-timer (p. 54). Still Images Changing the Focus Setting You can change default camera operation of constantly focusing on subjects it is aimed at, even when the shutter button is not pressed. Instead, you can limit camera focusing to the moment you press the shutter button halfway. z Press the n button, choose [Continuous AF] on the 4 tab, and then choose [Off] (p. 40). Helps avoid missing sudden photo On opportunities, because the camera constantly focuses on subjects until you press the shutter button halfway. Off Conserves battery power, because the camera does not focus constantly. 119
