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.|
