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.

Mount the lens on the camera by turning
the lens clockwise. Adjust its position.
