Abstract
Zoom lens assembly formed of a number of lens groups on a track. The lens groups can be moved on the track to form different lens effects such as zoom. The devices sense an end of travel in one direction using a hardware device. All the positions are relative to that end of travel, based on values stored in a memory, and by using the memory to drive the lens groups on the track.
