The invention relates to a stage device (1) comprising a fastening element (2), a bearing element (3) and a functional element (4), in particular a camera or a spotlight, the functional element (4) being mounted pivotably about a tilt axis (14) on the bearing element (3), and the bearing element (3) being mounted rotatably about a pan axis (13) on the fastening element (2), wherein a position-determining assembly is provided which is designed such that a relative movement between the bearing element (3) and the fastening element (2) and between the bearing element (3) and the functional element (4) can be determined. The invention also relates to a method for determining the correlation function of predefined tilt and pan values of a functional element (4), in particular of a camera or spotlight, to absolute movement values of the functional element (4).
