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.

As regards the dimension (b) of the area to which the lens is to be installed as illustrated on the left diagram, use the one with less value than what’s shown in the table below.

For both the C-mount and CS-mount, never use whatever exceeds the dimen- sion (b), as such will not allow normal installation and damage the inner part of the camera, resulting in a malfunc- tion.

Lens	Flange back (c)	Dimension (b)
C mount lens	17.526mm	5.5mm or less
CS mount lens	12.5mm	5.5mm or less

The F mark indicates a focal point.
