A motor vehicle camera module (12) having a lens assembly (20), a housing (22) forming a front end (50) surrounding an opening (28), an image sensor (24) carried by a back wall (32) within the housing (22) adjacent an image plane (A). The housing (22) having a lens holder (53) between the front end (50) and the back wall (32). The camera module (12) has a tube (26) fixed to the lens holder (53) at the front end (50). The tube (26) surrounds the opening (28) and extends from the opening (28) into the housing (22). The lens assembly (20) is connected to a tube bottom end section by threads (71, 72). The thermal expansion coefficient of the tube (26) is higher than that of the lens holder (53). The threads (71, 72) extends over less than half of the axial length (hL) of the lens assembly (20).
