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.

Lens	Flange back (c)	Dimension (b)

C mount lens	17.526mm	10mm or less

CS mount lens	12.5mm	5.5mm or less

The F mark indicates a focal point.

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