The article describes the design and application of a lens-converter specifically developed for intraoral photography: the Oral-Zoom-Converter. With a few simple manipulations this converter modifies an existing standard single-lens-reflex camera with an electronic flash unit into a compact intraoral setup which delivers excellent photographic results. A special optical mechanism allows for the continuous change of the magnification range between the overview range (lower half of the face) and the closeup range (2-4 crowns of teeth). The revolving friction-lock flash show positions the flash window on the appropriate side of the master lens for optimal illumination of the object. The cost of this converter will be moderate.
