Various Shooting Functions Changing the Sensitivity (ISO Setting) ISO sensitivity indicates how sensitive film is to light. A greater value means higher sensitivity. High sensitivity is suitable for shooting an object in a dark place or a fast-moving object while minimizing blurring. 1 You can select from the following ISO settings: Auto, Auto-Hi, ISO 80, ISO 100, ISO 200, ISO 400, ISO 800, and ISO 1600. When ISO setting is set to [Auto], the camera automatically changes the sensitivity according to the distance, brightness, zoom, macro settings, and picture quality/size. Usually, use the camera in the [Auto] mode. When the ISO setting is set to [Auto-Hi] (auto high sensitivity), the sensitivity is automatically set according to the shooting conditions but a higher upper limit than in [Auto] can be set. When shooting a dark subject, the shutter speed set in [Auto-Hi] is faster than in [Auto], which may reduce camera shake or blurring of the subject. The maximum ISO setting for [Auto-Hi] is specified in the setup menu. (GP.164) If you do not want to allow the camera to change the ISO sensitivity, select an ISO setting other than [Auto] or [Auto-Hi]. To change the setting, use the shooting menu or the ADJ./OK button. This section explains easy ways to change the setting with the ADJ./OK button. To use the shooting menu, see "Using the Menu" (GP.81). 1 Press the ADJ./OK button in shooting mode. 2 Press the ADJ./OK button #$ until the ISO setting menu appears. 3 Press the button !" to select the setting. 114
