A vehicular camera includes a lens holder accommodating a lens and an imager printed circuit board (imager PCB). The lens holder includes a plurality of posts protruding from an attaching portion of the lens holder. The imager PCB includes an imager disposed at a first side of the imager PCB, and includes a plurality of apertures therethrough. The attaching portion of the lens holder is positioned at the imager PCB such that the posts protrude through the apertures of the imager PCB. The posts are movable within the apertures while the lens is adjusted relative to the imager to align the lens relative to the imager. With the lens aligned relative to the imager, the posts are heated to deform within the apertures, whereby the deformed posts harden upon cooling to secure the lens holder relative to the imager PCB.
