Setting the Sensitivity

Sensitivity (ISO sensitivity) is a value indicating how much the CCD senses light. Low value equals low sensitivity, and high value equals high sensitivity. Sensitivity can be adjusted according to the shooting situations.

Sensitivity

	The camera automatically selects the sensitivity from 64, 100, 200, 400
AUTO	and 800. (In Blur reduction mode, 1600 is also selectable.)
	You can also set ISO Correction in AUTO to 64 - 100, 64 - 200, 64 - 400,
	or 64 - 800. (In Blur reduction mode, 64 - 1600 is also selectable.)

		conditions, but noise will increase.
