This adjusts the vertical synchronization to those of other cameras when a selector switch for the synchronizing system on the side is at LL. (50Hz power region only.) When it is not set to LL, “---” will appear, disabling change the set value. [Set value: –156 to 0 to 156]

This adjusts the horizontal synchronization to those of other cameras and systems when a selector switch for the synchronizing system on the side is at INT/GL. When external signals are not input, “---” will appear, disabling change the set value. [Set values: –16 to 0 to 16]

Coarse adjustment of the SC phase in gen-lock operation. The SC phase can be varied by up to 90° in each direction. Adjust with reference to another camera (or system) and together with the SC FINE adjustment. Adjust SC COARSE and SC FINE only after adjusting H PHASE. When it is not set to GL, “---” will appear, disabling change the set value. [Set values: 0°, 90°, 180°, 270°]

Fine adjustment of the SC phase in gen-lock operation. When it is not set to GL, “---” will appear, disabling change the set value. [Set values: 0 to 255]

The use of an electronic shutter function enables shooting with
proper brightness, as more brightness results in higher shutter
speed.
The ExDR function allows even the shooting of a subject having
different luminous flux density by composing a picture shot at 1/
100 sec. shutter speed with a picture shot by a high-speed
shutter.
NORMAL: This fixes the shutter speed to 1/50.
	The ExDR does not function.
MANUAL: This sets the shutter speed by the item SHUTTER
	SPEED on the SHUTTER screen.
	The ExDR does not function.
	When SENSE UP is functioning, MANUAL cannot be
AUTO:	selected. (Not displayed on MENU)
	This automatically switches the shutter speed
	according to brightness.
	The ExDR does not function.
	The item FAST LIMIT on the SHUTTER (ExDR) screen
M.ExDR:	sets a maximum shutter speed value.
	This is used when shooting a subject with difference
	in a luminous flux density in the screen under a fixed
	illumination condition, and so on. During ExDR mode,
	the item M.ExDR.SPEED on the SHUTTER (ExDR)
	screen sets the composing high shutter speed. It is
	possible to set only when the items BLC and SENSE
	UP are OFF. What’s more, the ExDR LEVEL sets
A.ExDR:	the signal level of the composing high-speed shutter.
	This is used when the subjects having different
	luminous flux densities are continuously used night
	and day in the situation where both indoor and
	outdoor subjects are mixed in existence, and so forth.
	During ExDR mode, the composing shutter speed
	automatically varies according to the contrast of a
	subject. This is set when shooting the subject with
	changing brightness.

ALC SETTINGS Screen
This makes automatic adjustments according to brightness.
Item	Functions and set values	Initial value
IRIS LEVEL	Adjusts the brightness level of the video signal.	NORMAL

•To lower the brightness level ... Decrease the value

•To raise the brightness level .... Increase the value [Set values: –5 to NORMAL to 5]

AVERAGE:	Sets the exposure detection as a ratio of the average value	8 : 2
PEAK	and the peak value.
	• AVERAGE value large: Increase the AVERAGE value
	when portions other than the highlighted areas of the
	screen are dark and look corrupted. (Ex. 10:0)
	• PEAK value large: Increase the PEAK value when
	halation occurs in the highlighted areas of the screen.
	(Ex. 5:5)
	[Set values: 10:0, 9:1, 8:2, 7:3, 6:4, 5:5]

This can be set only when the item BLC is OFF.

What’s more, the ExDR LEVEL sets the signal level

of the composing high-speed shutter.

MEMO

•Do not set to A.ExDR when using a manual lens.

•When M.ExDR mode or A.ExDr mode is used, the border between a bright part and a dark part can be coloured (cyan, orange, etc.), but this is not a malfunction.

•When the SHUTTER/ExDR item is set to M.ExDR or A.ExDR, a flicker can occur under a fluorescent lamp, mercury lamp, etc. However, this occurs by principle of the ExDR function, and therefore this is not a malfunction.

*When the SHUTTER (ExDR) item is set to NORMAL, the following items (SHUTTER SPEED, FAST LIMIT, ExDR LEVEL, and M.ExDR SPEED) cannot be changed.

SHUTTER	This sets a shutter speed when MANUAL is set.	1/120
SPEED	The AUTO, M. ExDR, A. ExDR set value is displayed as
	“- - -” and cannot be changed
	[Set values: 1/120, 1/250, 1/500, 1/1000, 1/2000, 1/4000, and
	1/10000]
