Adjusting Camera Lens Focus with Front Focus Ring
You can sharpen the camera lens focus by adjusting the focus ring at
the front of the lens. The procedure in this section applies to both
fixed-focus and zoom lenses.
You can see the results while you are focusing the camera by viewing
the markers in your Vicon application software. For example, in
Nexus, you can view the camera data in a Camera view pane. In
Vicon iQ, you can view the camera data in a Camera view pane or a
Fullscreen Preview view pane. In Workstation you can view the
camera data in a Live Monitor window, and optionally in Preview
mode.
The following procedure contains examples outlining how to view the
live camera data in Nexus, in Vicon iQ, and in Workstation. For full
details on the software steps, see the documentation for your Vicon
application software.
To adjust camera lens focus with the front focus ring:
1. Mount the camera on a tripod within r e a ch o f t h e ho s t P C on w h ich
the Vicon application software is installed.
2. Ensure that you can view the camera data from the Vicon
application software on the host PC. For details on doing this, see
the documentation for your Vicon application software.
3. Place a pair of 25 mm retroreflective markers with centers 50 mm
apart central to the camera Field of View and at a distance from
the camera representative of the capture distance.
4. If focusing a zoom lens, set the zoom to the desired level.
5. Ensure that the lens aperture is at its most open setting, that is,
it is set to the lowest numerical value on the aperture ring (shown
in Figure C-1). This lets more light into the camera and minimizes
