Check the mounting method of the lens to
be used before mounting
● The default method used for this camera is
CS mount. To use a C mount lens, loosen the
back focus fastening screw using a
screwdriver, followed by turning the back
focus adjustment ring using a finger or
pointed object (e.g., screwdriver, etc.) to
change the mount method.
● Make use of the values listed in the table
below for the dimensions of the lens mount
(a) indicated in the following diagram.
● Objects longer than the dimension (a) must
not be used as doing so may damage the
camera interior or prevent the lens from
being properly mounted, hence resulting in
malfunctions.
