<p>An endoscope (10) includes a focusing mechanism (17) having a focus control element (80) at a proximal end (19) of the endoscope and a mechanical coupling connecting the focus control element (80) to an image transmitting device (e.g., an electro-optical sensor (24) or one or more optical fibres (26)) mounted at a distal end (14) of an elongated insertion section (12) of the endoscope (10). Rotation of the focus control element (80) moves the image transmitting device (24) with respect to a lens assembly (22) of the endoscope (10) to focus the image received by the lens assembly (22). <IMAGE> <IMAGE></p>
