Lens mounting procedure
1.
Check the mounting of your lens before attaching it to the cam-
era. The camera has been set for a C mount before shipment
(Figure 1-1). When mounting a CS-mount lens, loosen the BF
LOCK screw (
on page 4) by turning it counter-clockwise and
turn the backfocus adjustment ring ( on page 4) in the direc-
tion of the arrow in Figure 1-1 to switch the mounting method.
(Figure 1-2 shows the camera set for a CS mount lens.)
Lens
Caution
• The ring cannot be turned by more than a certain amount with
your finger. Use a thin object (screwdriver tip, etc.) to turn the
ring (Figure 1-3).
• Distance L of the lens mounting section shown in the follow-
ing illustration should comply with the condition shown in the
following table. Never use a lens with a flange back distance
L greater than, the one Specified in the chart below. As this
will damage the inside of the camera or may make normal
mounting impossible. Also, be careful not to attempt to mount
a C-mount lens while the camera is set for a CS mount.

2.
Mount the lens on the camera by turning the lens clockwise
and adjust its position.
3.
When an auto-iris lens is used, also connect the lens cable to
the camera.
If the lens does not incorporate an EE amp, connect the
cable to the DC IRIS connector on the side panel (Figure 2-1).
If the lens incorporates an EE amp, connect the cable to
the VIDEO IRIS connector on the rear panel (Max 50mA).
