Lens usage
The lens is controlled via the lens control feature in the GenICam tree of the
camera. When activating the power supply or attaching a new lens, a lens init
should be performed automatically. You might use the init command any time,
be aware of initialization time.

Limitations
>
Zoom function is not supported
>
Focus and iris do not support feedback control. If focus or iris is altered by
external effects, the lens/camera will not correct this automatically. A lens
init is required to restore the synchronization of camera and lens
>
GenICam numbers for adjusting focus and iris do not show calibrated val-
ues (in units like m or f-stop numbers)

API-calls
The adapter can be accessed through the camera’s GenICam properties, the
adapter has no API on its own. The SVCam Kit provides software access to the
GenICam properties of the camera and thus to the properties of the adapter as
well (see
). Only SVCam cameras with matching firm-
ware support provide access to the lens in its GenICam tree.
The camera provides following lens properties:
