A vehicular camera includes a circuit board having an imager disposed at a first side of the circuit board. A lens barrel includes a lens assembly having a plurality of lens elements spaced apart along the lens barrel by respective lens spacers, each lens spacer formed of a material having a coefficient of thermal expansion (CTE) of 10 ppm/° C. or less. The circuit board is positioned at the lens holder, and the lens barrel is positioned at a lens holder so as to optically align the lens and the imager. The lens barrel is formed of a material having a CTE that matches within ten percent of the CTE of the material that forms the lens holder, with the CTEs of the lens barrel and lens holder materials being greater than the CTE of the material of the lens spacers.

A follow focus enabling a user to move quickly move into and out of a hard stop operation. A soft stop orientation provides haptic feedback at manually calibrated focusing settings.

A vehicular camera includes a lens barrel, a lens holder and an imager PCB. The lens barrel accommodates a lens and has a threaded inner end. The lens holder has a threaded passageway for threadedly receiving the threaded inner end of the lens barrel. The lens barrel is threadedly attached to the lens holder with a biasing element applying a biasing force at the lens barrel to urge the lens barrel in a direction outward away from the lens holder. The imager PCB is attached to the lens holder with an imager of the imager PCB facing the lens, and the imager PCB is adjusted relative to the lens holder and lens barrel construction to optically align the lens at the imager. After the imager PCB is secured relative to the lens holder, the lens barrel is rotated to adjust focus of the lens at the imager.
