1. A method of operating a surgical microscope, the surgical microscope including at least one camera having a zoom lens, a support for the at least one camera, the support including at least one actuator for positioning the at least one camera relative to an object; and a display configured to display images obtained by processing the images recorded by the at least one camera, the method comprising:
positioning the at least one camera to have an initial position relative to the object and displaying the images obtained by processing the images recorded by the at least one camera such that centers of displayed images correspond to a first position within recorded images and such that a magnification of the object displayed in the images is a given magnification;
receiving an instruction at a first time to move the at least one camera relative to the object to a target position; and
in response to the instruction to move the at least one camera:
zooming out by operating the zoom lens until a field of view of the at least one camera at the target position comes into a field of view of the images recorded by the at least one camera;
cropping the images recorded by the at least one camera such that the field of view of the displayed images corresponds to the field of view of the at least one camera at the target position;
displaying the images obtained by processing the images recorded by the at least one camera;
moving the at least one camera to the target position by operating the at least one actuator; and
