ABSTRACT:
An optical system of changeable magnification comprising a master lens arranged normally in axial alignment to an image receptor to be switchable to another light path which includes a rear converter, and a reflection mirror arranged so that when the master lens is switched from the first to the second light path, the light emerging from the converter is directed to the image receptor, while blocking the first light path off the image receptor, thereby the image magnification is changed from one value to another.
