Zusammenfassung:	A system for determining a distance to a region of interest. The system may be used to adjust focus of a motion picture camera. The system may include a first camera configured to have a first field of view, and a second camera configured to have a second field of view that overlaps at least a portion of the first field of view. The system may include a processor configured to calculate a distance of the selected region of interest relative to a location by comparing a position of the selected region of interest in the first field of view with a position of the selected region of interest in the second field of view.
