Zusammenfassung:An endoscope has an eyepiece with an optical system (16) comprising a series of lenses (18) housed in a sleeve (20) which is movable longitudinally in the endoscope casing for focusing an image. An adjusting ring (26) is rotated to adjust the position of the sleeve (20), to focus the image for viewing by the eye. For viewing of the image by a camera, an adaptor (38) is fitted on the end of the endoscope eyepiece. The adaptor (38) has a slot (44) which receives a fixed projection (36) and a movable projection (30) on the adjusting ring (26). Rotation of the adaptor (38) rotates the ring (26) and thereby shifts the sleeve to a predetermined longitudinal position suitable for viewing of the image by a camera.
