A vehicular camera system includes a vehicular camera including a camera housing and an imager printed circuit board (imager PCB). The camera housing includes a first portion and a second portion joined with the first portion. The first portion includes a lens barrel accommodating a lens that includes a plurality of lens optics. The imager PCB includes an imager and is attached at the first portion of the camera housing with the imager aligned with the lens. With the imager aligned with the lens, the lens focuses an image at the imager. After the imager PCB is attached at the first portion of the camera housing with the imager aligned with the lens, at least one lens optic of the lens is laser processed to adjust the focus of the lens at the imager.
