Summary:A video endoscope having a handgrip and shaft having a cladding tube, wherein a prism unit having at least two prisms is connected to the cladding tube, wherein at least one distally arranged prism is rotated to modify a viewing angle around a rotation axis, an inner positioning system that comprises at least one rotational body arranged on a rotation axis of the shaft, axially fastened, and rotatable around the longitudinal axis of the shaft, to the distal tip of which the at least one image sensor is fastened, and at least one axially movable translational body, wherein a drive device is configured such that upon actuating a first control element, only the rotational body is rotated, and upon actuating a second control element, the translational body is moved and the rotational body is rotated such that a horizon position of an image formed on the image sensor remains constant.
