Zusammenfassung:	A lens assembly includes a lens group, a plurality of cover units, a lens frame, and a rotary cam. The cover units, operating in an operating space, can be spread to cover the lens group and overlapped to expose the lens group. The lens group and the cover units are supported by the lens frame. In rotation, the rotary cam drives the lens frame to move along the optical axis, thus spreading or overlapping the cover units. The rotary enters the operating space when the cover units are spread to cover the lens groups, and leaves the operating space when the cover units are overlapped.
