1. A device for actuator-driven adjustment of incremental magnification levels of a magnification changer, comprising:
at least one sensor coupled to the magnification changer that detects and transmits a currently selected incremental magnification level to a control unit;
the control unit including a stored assignment in memory of the incremental magnification levels that are available to be selected on the magnification changer in a sequence of the incremental magnification levels ordered according to numerical size;
at least one operating element that enables choosing a desired magnification level, wherein the at least one operating element that enables choosing the desired magnification level is presented to a user and is connected to the control unit; and
the magnification changer that sets the magnification level chosen by the user via the at least one operating element further comprises an actuator which is connected to and controlled by the control unit and which receives corresponding control signals from the control unit and that is operably mechanically coupled to the magnification changer to change the incremental magnification level thereof.
