ABSTRACT:
A unidirectional focus control system for a variable focus lens moves said lens outside of its normal focusing range in order to establish a reliable reference point to which or from which said lens is moved for variable focus lens focusing. In addition, lens movement outside of its normal focusing range provides the means for actuating switch means whose actuation initiates or inhibits the initiation of an event or a series of events.
