An imaging apparatus for influencing impinging light comprising an optical element and an actuator for deforming the optical element is proposed. The optical element has a surface facing the impinging light and the actuator (3) has at least one piezoelectric element. In this case, the piezoelectric element is able to be driven by means of a control device. Moreover, the piezoelectric element is fitted to a rear surface and/or to that surface of the optical element which faces the impinging light. The optical element is borne by means of at least one such bearing element that has direction-dependent compliances for in each case at least one degree of freedom of rotation and/or degree of freedom of displacement, such that it is possible to achieve a substantially longitudinal-force-free bending with a substantially fixed overall position of the optical element.
