An endoscope with an adjustable viewing direction includes a shaft, an image transmission device for transmitting an image from a distal end of the endoscope to a proximal end of the endoscope, a hermetically tight sheath around the image transmission device, with a light admission window at the distal end of the endoscope, a manipulating device at the proximal end of the endoscope, a swivel actuation device on the manipulating device for manual adjustment of an angle between the viewing direction and a longitudinal axis of the shaft, a magnetic coupling device for magnetically transmitting a force, parallel to the longitudinal axis of the shaft, between the swivel actuation device and a force transmission device inside the hermetically tight sheath, and a rotation actuation device on the manipulating device for manually rotating the viewing direction about the longitudinal axis of the shaft relative to the manipulating device.
