3.4Lens mounting

The camera accepts CS-mount lenses. C-mount lenses can be mounted using a lens adapter ring. 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.

CAUTION!

To avoid damaging the CCD sensor when using a C-mount lens, make sure a lens adapter ring (not included) is mounted onto the camera before mounting the lens.

Lenses weighing more than 0.5 kg (1.1lbs) must be separately supported.
