3.1 Lens mounting
The camera accepts CS-mount lenses with a lens protrusion of
up to 5mm. C-mount lenses can be mounted using the lens
adapter ring. DC-iris lenses are recommended for the best pic-
ture performance. The camera automatically detects the type of
lens used and optimizes performance accordingly. A spare male
lens connector is provided.

To avoid damaging the CCD sensor when using a C-mount lens,
make sure the supplied lens adapter ring is mounted onto the
camera before mounting the lens.
Lenses weighing more than 0.5 kg (1.1lbs) must be separately
supported.
