The Spyglass has to modes of automatic camera controls. It can automatically focus
Usually, the Spyglass focuses the camera only once. If you want to let your camera
follow a person, you could turn on "tracking." Open the menu, go to the "Camera"
menu, and then choose "Tracking." Clicking that button will turn tracking on/off.
(Note that it can't follow smoothly. If you want the camera to follow the
avatar smoothly, use the feature built into the Second Life viewer:
Hold down the
Alt key and click the avatar you want to follow.)
To stop autofocusing and/or tracking you could turn the modes off in the menu or just click the "Reset" button on the HUD.
