A camera for a vehicular vision system includes a housing and a lens barrel including a lens. The camera is configured to be disposed at an exterior portion of a vehicle so as to have a field of view exterior of the vehicle. A heating device is disposed at an exterior of the lens barrel. The heating device includes a thin foil heating element that at least partially circumscribes the lens barrel. The heating device includes an electrical lead that is configured to electrically connect to an electrical connector of the vehicle when the camera is disposed at the exterior portion of the vehicle. Responsive to a determination of current drawn by the heating device, a control of the camera determines the temperature at the lens and controls operation of the heating device based at least in part on the determined temperature.
