Lens mounting
The camera accepts C-mount and CS-mount lenses. DC-iris
lenses are recommended for the best picture performance. The
camera automatically detects the type of lens used and
optimizes performance accordingly. A spare male lens
connector is provided.
Note
If a short circuit is detected on the lens connector, the on-
screen display (OSD) failure message LENS SHORT CIRCUIT is
shown. The lens circuit is automatically disabled to avoid
internal damage. Remove the lens connector and check the pin
connections.
CAUTION!
To avoid damaging the CCD sensor when using a C-mount lens,
turn the green back-focus ring counterclockwise until it stops
before mounting the lens.
Lenses weighing more than 0.5 kg (1.1lbs) must be separately
supported.
