EI (Electronic Iris) Switch Settings 4, 3, and 1
The EI (Electronic Iris) feature compensates for an excessive light level by
automatically adjusting shutter speed. Selecting Electronic Iris disables
manual shutter speed selection. The Electronic Iris setting must not be used
when the camera is set to Flickerless mode. Following are the EI switch
settings:
ON (Default setting) - Enables the Electronic Iris mode.
OFF - Disables the Electric Iris mode.
BLC (Backlight Compensation) Switch Settings 2 and 4
The BLC (Backlight Compensation) feature compensates for backlit scenes
by enhancing objects in the center of the scene that would previously have
been in silhouette. BLC will only function with a manual iris lens when the
Electronic Iris feature is switched on. For direct drive and auto iris lenses,
BLC will still function even though the Electronic Iris feature is switched off.
Following are the EI switch settings:
ON - Enables the BLC mode.
OFF (Default setting) - Disables the BLC mode.
Flickerless Switch Settings 4, 3, and 1
The Flickerless setting can reduce the flicker caused by certain lighting condi-
tions. The Electronic Iris setting must be off for correct operation of the
Flickerless function. Choose between the following settings:
ON - Enables the Flickerless mode.
OFF (Default setting) - Disables the Flickerless mode.
