MEMO

•When the shutter speed is slower than 1/4 s (1/15 s in the VGA DRAFT mode), the screen update rate becomes longer in correspondence with the shutter speed, and time will be required for the following operations.

Auto white, auto iris, ALC

If the shutter speed is set at 1.4 s or slower, these opera- tions behave as follows.

Auto white : Auto white balance function cannot be started. (
page 30 White balance adjustment)

Auto iris : Stops at the iris value at that time.

ALC : Stops at the sensitivity at that time.

To use a shutter speed of 1.4 s or slower, use with the following settings selected:

IRIS MODE :	MANUAL
SENSITIVITY :	STEP or V.SENS

•There may be shortage of light when increasing the shut- ter speed. In this case, adjust the iris or sensitivity. Spe- cial attention is required for the picture quality when rais- ing the sensitivity since images may show artefacts.

SENSITIVITY		Used to set the sensitivity mode.		STEP
		STEP:	the sensitivity can be changed by means of the
			LEVEL submenu item.
		ALC:	the sensitivity si automatically changed by the
			ambient brightness. Maximum sensitivity is set
			in the next ALC MAX menu item.
		V.SENS: the sensitivity can be set in detail using the
			LEVEL submenu item.
	LEVEL	The sensitivity can be changed when the sensitivity mode		STEP:
		is set to STEP or V.SENS.		ISO100
		[STEP variable range: ISO100, ISO200, ISO400]		V. SENS:
		[V.SENS variable range: ISO100 ~ ISO400]		ISO100
ALC MAX		This can be set when the sensitivity mode is set to ALC.		ISO400
		Used to set the maximum sensitivity of ALC, which automati-
		cally switches the sensitivity depending on the brightness.
		[Variable range: ISO200, ISO400]
