When introduced the Primarflex was of unusual shape for a single-lens reflex which commonly adopted the 'T' shape of the Exakta or the box shape of the KW and Mentor. The shape was later to become popular with the Hasselblad. A very wide range of lenses up to 40 cm was available.

Minor differences in finish exist and after World War II the camera was re-styled.
