At last the «lens mount» is in place on the Giant Mobile Camera, and now it is possible to change between different holes, and even lenses, too.

This is the lens mount. It has an old lock system from a Graflex Crown Graphic to hold the «lens plates»

«Lens mount» from inside. The «lens plates» are mounted from inside the Cameravan. In case of a lens, it can also be mounted and handled inside the camera.

An old Compur shutter with all the shutter mechanics removed functions as a variable aperture. Quite nice, I think 🙂
Next is to make different shaped holes for demonstration purposes, for this I will be using slide frames with black tape inside. I have a «lens plate» ready for this. I will also make a holder for a 600 mm Apo-Ronar lens.
