Prominent was the lowest-priced of the top German cameras and the most intelligent system. It had a very special and unique reflex-housing part and turnit finder as accessories. Though producing the same picture quality, and although a lot less expensive than its counterparts, the Prominent never became popular with experts: it neither offered a great range of lenses nor did it have that special 'feeling' of a Leica or a Contax. It was the first range finder camera with leaf shutter and interchangeable lenses. The Prominent was introduced as a counterpart to the famous Leica and Contax cameras, and featured astonishing new technical details.

Prominent II is one of the best mechanically and optically designed rangefinder with interchangable lens system camera, the first of this type and has a unique appearance. Prominent I is certainly the first of this type.
