A lens out of a Zeiss Ikon folding camera.
The Frontar is a single lens element with low speed. In the camera it has an aperture revolver but I gave the lens a diaphrame aperture of an Industar 50mm lens and a Helicoid of a very old Schneider Componar and a T2 screw mount socket.
The max. speed of the lens is now f/6.5 and for this sample I used f/11
