An optical system affords wide-angle imaging with a width in azimuth and a height in elevation respectively greater than and less than those of the field of view of an imaging device to which it is fitted. A median optical axis images a central format view on the optical axis of the imaging device, and two lateral optical paths image two lateral format views on a bearing axis at a bearing angle to the optical axis equal to the width in azimuth of the field of view of the imaging device. The three paths juxtaposed in the wide-angle field of view are superposed into a resultant format image.
