5. Set "IRIS SET MODE" to "OFF". (Exiting from this
menu mode will automatically change the setting to
"OFF")
Notice
When this setting is set to "ON", the iris control from
the remote controllers is disabled. When the lens is
installed in the camera for the first time, or if the
hunting problems still exist or response is still slow
even after the settings are adjusted, adjust the
sensitivity of the auto iris lens.
For details, refer to "4.5.1 How to Use the B4 Mount
Lens", " AUTO IRIS Operation".
[B3 Mount Lens]
Sets the level of auto iris function. To always obtain the best
video level even if the amount of light changes, the iris must
be controlled. Set "IRIS SET MODE" to "ON" first. This will
enable the setting of the "IRIS LEVEL SET" and "PEAK
RATIO SET" described below.

PEAK RATIO SET
[B4 Mount Lens]
Adjusts the iris when contrast between light and dark, such as
spotlight and backlight, is high. Set the exposure for a bright
area with the "PEAK RATIO SET" settings in the "+"
direction, and for a dark area in the "-" direction.
The default value is "0" which indicates no exposure
compensation. Before setting "PEAK RATIO SET", turn ON
"IRIS SET MODE".
