Mount the lens according to the procedures described below.

1.
Before mounting a lens, check whether
it is a C-mount or CS-mount lens.
To change the mounting method, loosen
the back-focus locking screw (M 2.6)
using a Phillips head screwdriver, turn
the back-focus adjusting ring with your
fingers or the screwdriver and change
the mounting method.
Dimension (b) of the lens shown in the
illustration must be as shown in the table
below. If (b) exceeds the value in the
table, it may damage the inside of the
camera or correct mounting may be im-
possible; never use such lenses. Do not
attach the C-mount lens when using a
CS-mount.
The F mark indicates a focal point.
2.
Mount the lens on the camera by turning
the lens clockwise. Adjust its position.
3.
When using an auto-iris lens with an EE
amplifier, turn the switch to the “VIDEO”
side. When no EE amplifier is equipped,
turn the switch to the “DC” side.
4.
If the lens has an auto-iris mechanism,
connect the lens cable after checking the
pin arrangement.
If the lens cable has a different type of
plug, use the 4-P plug supplied.
