1-1 Attaching a Lens
Attach a lens in the following procedure.
1.
Before attaching a lens, check the mount
method of the lens.
VN-C11 is set for CS-mount at the factory. For
attaching a C-mount lens, loosen the back-
focus locking screw using a screwdriver and
turn the back-focus adjustment ring to change
the mount method accordingly with a finger
or a pointed tool like a screwdriver.
To attach a lens, observe the length shown
as (a). Do not use a lens with a length longer
than (a) as it may cause damage to the inter-
nal parts of the camera and proper lens at-
tachment would not be possible.
2.
Attach the lens to the camera securely by turn-
ing it clockwise.
3.
In the case of a DC IRIS lens, connect the
lens cable to the socket while examining the
pin arrangement.
