Abstract: An optical system comprises a lens system having at least one movable lens; a lens housing having an opening, the lens housing attachable to an image sensor so that the lens, the opening, and the image sensor are arrangeable along an axis with the opening between the lens and the image sensor; a probe extending towards the opening and that is fixed in relation to the lens; an actuation system for moving the lens along the axis and the probe parallel with the axis, so that the probe reaches out to a location where the image sensor is arrangeable; and a control system for controlling the actuation system to move the lens and the probe and to detect that a motion of the lens and the probe is prevented by the probe hitting a surface fixed in relation to the image sensor.
