Note
z Adjusting ISO Sensitivity (Recommended Exposure
Index)
ISO sensitivity is a speed rating for recording media that incorporates an image sensor that
receives light. Even when the exposure is the same, images differ depending on the ISO
sensitivity.
High ISO sensitivity
Records a bright image even in dark locations while increasing shutter
speed to reduce blur.
However, the image tends to become noisy.
Low ISO sensitivity
Records a smoother image.
However, when the exposure is insufficient, the image may become
darker.
z Hints for preventing blur
Even though the camera is steady, the subject moves during the exposure and is captured
blurred when the shutter button is pressed. Camera shake is reduced automatically,
however, the function does not effectively reduce subject blur. Subject blur occurs
frequently under low-light or slow shutter speed conditions.
In such a case, shoot with the below tips in mind.
• Select a higher ISO sensitivity so that the shutter
speed is faster.
• Select (High Sensitivity) mode in Scene
Selection.
