An endoscope with a coupling device for the connection of a video camera, wherein the endoscope has, at its needle-shaped tube, a distal end which is provided for insertion into the body and a lens system and has a proximal end provided for looking into the endoscope and having a field diaphragm, the coupling device being attached to the proximal end, and wherein a lens system is arranged following the field diaphragm and, like the lens system at the distal end, is sealed off from the outside completely and tightly and is constructed so as to be non-adjustable and non-focusable. The coupling device has no lenses and is adjustable with respect to its axial length in the manner of a telescope.
