A camera frame assembly has an extendable lens module having a lens base, a traveler, a front lens element, and a barrel cap. The lens base defines an optical axis. The traveler moves along the optical axis between first and second positions, relative to the lens base. The traveler has a front lens seat. A front lens element is disposed in the front lens seat. A barrel cap is snapped on the traveler. The barrel cap retains the front lens element in the traveler in alignment with the optical axis. The barrel cap can be snapped off for replacement by a new or renewed barrel cap. When the barrel cap is off, the front lens element is released and can be replaced or can be held in place for reuse.
