Calibration of the lens aperture

To be completed soon...

 

1) Inner barrel with the aperture block mounted.
2) The bronze ring rotates and actuates the cam, pushing the metal lever outwards. This lever opens and closes the aperture
3) Approximate position of minimum aperture. This aperture has to be calibrated to the maximum f-stop of the lens (f/16).
4) The metal stop should be calibrated for maximum aperture (f/1.4).
5) Cam actuating on the maximum aperture position.
6) ???
7) Aperture scale ring engages with the aperture mechanism trhough this coupling. This can be calibrated too.
8) Aperture actuated to the maximum aperture.
