A micro video imaging camera has a detachable distal module which is replaceable with one of different characteristics (e.g., angled), and sterilizable. Thus a non-replaceable CCD and video transmitter are connected to an inner body which comprises in effect a lens tube. The module comprises an outer body encasing the inner body which has a filter (optional) at its tip and a magnifying lens optically connected to an image conduit optical segment. The inner body receives the image conduit, the output of which is focused by the lens in the inner body on a CCD microprocessor. The model may be replaced with an angular distal end or lenses of different fields of view. Fiber optic light filaments may be used to illuminate the field of view of the tip of the module, either housed internally or externally of the inner body.
