Camera assembly for a vehicle. A sensor subassembly includes a rear housing and a circuit board fixed to the rear housing. The circuit board includes an imager. An optical subassembly includes a lens and a lens holder for holding the lens. The lens holder forms a front housing mated to the rear housing. The optical subassembly is fixed to the sensor subassembly by a cured adhesive applied at a mating interface between the lens holder and the rear housing to align the optical subassembly to the sensor subassembly for focusing the lens on the imager.
