Abstract
A lens assembly for a camera including a first lens mounted to a base portion, and a second lens mounted to a lens frame, where the first lens and the second lens are positioned co-axially along a central axis. The lens assembly includes a linear guide system for maintaining alignment of the first and second lenses. An embodiment of the linear guide system includes a first elongated element elongated along a longitudinal axis extending therethrough, parallel to and offset from the central axis. The elongated element may support and guide the lens frame for linear movement along a linear path parallel to the central axis. Some embodiments of the lens assembly include a second elongated element or rotation restriction element.
